10 h 00 - 12 h 00Morning Workshop #3 (2 hours): Automated Bathymetry Updates with ArcGIS for Maritime Presented by Esri
Speaker: Kevin Ingram, Senior Technical Manager - Maritime, Esri
Speaker: Rafael Ponce, Executive Consultant - Maritime Services, Esri
Some of the most time-consuming work in hydrography is analyzing new bathymetry, comparing it in context with prior surveys and other data, and updating navigation products at various scales and formats with the new survey. Technical staff from Esri will show how the scripting capabilities within the ArcGIS platform automate this work. During the workshop, participants will see how ArcGIS for Maritime ingests a final bathymetry survey, automatically identifies the affected vector and raster charts, uses best-in-class tools to generate shoal-biased soundings and depth curves at appropriate scales, and updates all the affected products.
Morning Workshop #4 (2 hours): Combining Wide Swath bathymetry with 3D Sidescan Sonar Imaging – An Introduction to and Demonstration of the 3DSS Sonar Presented by Ping Inc.
13 h 00 - 16 h 30Afternoon Workshop #1 (half day): Implementation of an Unmanned Surface Vehicle and Echosounder into the Land Surveyors Workflow Presented by Seafloor Systems, Inc.
When conducting typical topographic survey operations, Land Surveyors frequently come across water features such as rivers, lakes, ponds, and streams in their area of operation. The common practice in this case is to utilize a rod extension from a small boat to conduct observations. This can be expensive, time consuming, and tedious. By integrating a small, portable USV equipped with an echosounder device, the topographic surveyor can quickly and easily collect continuous topographic survey data utilizing their existing survey gear and workflow process.
Afternoon Workshop #2 (half day): Maximizing Survey Efficiency and Data Quality with Sound Velocity Profiling Presented by AML Oceanographic
Whether you are surveying shallow, coastal waters in a small boat or deep waters on a large research vessel, sound velocity profiling affects your survey operations and results.

Lecture Hall - Victoria Convention Centre
Eric Peterson, Founder & President, Tula Foundation / Hakai Institute
At the Hakai Institute (hakai.org) we study British Columbia’s coastal margin, and in particular the complex 300-kilometer stretch between our two ecological observatories that are located respectively on Quadra Island at the north end of the Salish Sea, and on Calvert Island halfway to Alaska. This stretch of coastline is critically important; for example it is the route taken by Fraser River salmon as they transit to and from the Gulf of Alaska. Fjords extend inland from this waterway to the mountain glaciers deep in the Coast Range. Topography and hydrology are critical determinants of ecosystem function, which is particularly sensitive quantity and temperature of flow through the watersheds and into the ocean. Climate change—in particular the rapid retreat of the coastal glaciers—is already causing profound changes to this landscape, and these changes will likely accelerate over the coming decades. As part of our research into these changing dynamics, we use geospatial tools and analysis, including satellite imagery, airborne LiDAR, UAVs (drones) and multi-beam SONAR.

The goal with the Kognifai open platform ecosystem is to level the playing field and let everyone participate: customers, partners, vendors, ISVs, industry clusters, and entrepreneurs alike. Whether you work for a small company with limited resources or a large multinational organization, whether you own industry assets or is a vendor delivering services to it, Kognifai is open to everyone who wants to participate and help transform the industry through digitalization. KognifAI allows sonar data from multibeam echosounders and other sensors to be stored in a cloud environment. The data can then be processed in near real time and made available for distribution immediately. The Seafloor Information System is the logging system for Kongsberg Multibeams and together with the post-processing software SIS Plus it allows operators to store data in the KognifAI ecosystem. From there various products can be made by combining sonar data with data from other sources to provide the end-user with a complete understanding of the environment. These products can be available to everyone with access to KognifAI, from anywhere in the world, enabling both true remote control of an ongoing operation and access to results from previous operations.
10 h 00 - 12 h 00CHC Technical Session: PLANNING, FRONTIER-AREA SURVEYS, RESURVEY, HYDROGRAPHIC RISK AND UNCERTAINTY
Lecture Hall - Victoria Convention Centre
Moderator: Shelly Leighton, Marine Institute
10 h 00 - 10 h 20Hydrographic Risk Assessment - Antarctica
Lecture Hall - Victoria Convention Centre
John Riding, Marico Marine NZ Ltd
The updating of Nautical Charting, based on risk is a relatively new science and a published methodology has only recently been endorsed by the IHO. A number of Hydrographic Risk Assessments have been undertaken, most recently for the whole of New Zealand EEZ waters and an approach to cost benefit for charting upgrades has been developed. Another large risk Assessment is progressing, this time covering the Antarctic waters of the Ross Sea together with the waters surrounding the remote Sub-Antarctic Islands. The development of appropriate risk criteria for risk calculations for this area is challenging, as the environment is key. Ship traffic is low, making risk definition between locations difficult to quantify, but the level of cruise interest is rising year on year. This paper explains the approach used to develop a Hydrographic Risk profile for these remote waters and with the permission of Land Information New Zealand (LINZ), will share some preliminary results.
10 h 20 - 10 h 40Yukon River Delta Investigations to Support Satellite Derived Bathymetry Validation
Lecture Hall - Victoria Convention Centre
Damian Manda, NOAA
The Yukon River delta presents challenges for maintaining updated navigation charts. Every year, the channel can significantly shift due to the influence of ice and high currents during spring runoff. Yearly resurvey is impractical due to the large size of the river delta and remoteness of the area, but the channel provides a critical pathway for goods delivery to over 100 villages upriver so supply boats navigate blindly each spring, often repeatedly running aground on initial attempts. In order to provide a more adequate chart product, NOAA has investigated alternative methods of updating hazards and defining the safe channel. While the channel is shallow, sediment in the water prevents airborne lidar survey. Additionally, traditional satellite derived bathymetry (SDB) methods are not possible, but a specialized type defining shoals and channels by color relating to the density of the sediment was developed and has been previously detailed in multiple papers. In 2017, NOAA Ship Fairweather was tasked with collecting the first actively sensed bathymetric data in the Yukon river delta since 1899. The survey methodology targeted defining a navigable channel through the delta and investigating the efficacy of the specialized SDB approach in this area. Acquisition planning was guided by AIS data and a color coded SDB rendition. Survey launches with multibeam echosounders were primarily used for depth measurement, supplemented by a shallow draft jet boat mounted water single beam. The bathymetric survey results are presented, along with supplementary data about the delta including CTD profiles and currents. An analysis of calibration and comparison between the SDB and measured depths examines its applicability to charting. The results of Fairweather’s work in the Yukon River delta will place the first updated soundings on the chart for over 100 years and facilitate an understanding of methodology for more rapid updates in the future.
10 h 40 - 11 h 00A crowdsource approach for capacity building in North Canada
Lecture Hall - Victoria Convention Centre
Julien Desrochers
A crowd-sourced bathymetry (CSB) scenario has been designed for the Northern Canada area as a response to situations where the lack of hydrographic infrastructure makes soundings reduction from basic depth measurements very challenging and where the data redundancy is not sufficient to use solely statistical tools as a mean of sounding estimation. The CSB scenario consist to train Innuit communities to the use of pre-qualified and integrated single beam systems. The pre-qualified system used are Hydroballs, developed by CIDCO. The first pilot project occurred during the summer 2017, and involve two communities located in the Quebec province (Kuujjuarapik and Quaqtaq). The presentation will detail the systems used, how the have been deployed in these two communities, how we trained local people to used them and what are the benefitsof this project for the local communities. In particular, we will detail the lesson learned throught these two deployments, and how the CSB scenario we used could be generalized to contribute to the IHO capacity building programmes. This work has been conducted in the framework of the project “Crowd-Sourced Bathymetry in the Northern Canada area”, a project gathering the following partners from the COMREN network: - UNB (NB) - York University (ON) - Marine Institute (Memorial University) (NL)
11 h 00 - 11 h 20Morphological Evolution of Nearshore Sandbank System Using Repeat Multibeam Sonar Surveys: Examples from the East Coast of the United Kingdom
Lecture Hall - Victoria Convention Centre
Majed Salama Almehmadi, University of Southampton/King Abdulaziz University
The Inner Great Yarmouth sand banks (IGYSB) are a group of mobile nearshore banks in the southern North Sea, off the East Anglian coast in the United Kingdom. IGYSB movement can be hazardous for navigation, as access to two ports in the region is controlled. Therefore, a better understanding of the banks’ short-term trends and patterns can be employed to influence hydrographic surveying programme development strategies by focusing on the most highly dynamic areas. Time series data for 50 multibeam swath bathymetry surveys for the IGYSB system were undertaken from 2004 to 2015. The results of the trend analysis indicate that the IGYSBS are highly dynamic and have undergone significant morphological changes, with short-term variations from one bank to another due to hydrodynamic variations at their geographical location. The gross movement of the banks illustrates complex patterns demonstrating northern migration, as well as an increase in the banks’ physical extent in the alongshore direction. The results further illustrate that this migration is due to the shoaling and breaking of waves. The forward-backward motion of the flood and ebb provides additional erosional action of the sediments by means of traction, saltation, and suspension. The dominant factor of the banks’ migration is primarily controlled by large-scale, competing, and seasonal weather changes. The average maximum migration rates of the IGYSB system over the 11-year period were approximately 60.9 m yr-1; the average minimum migration rates were approximately 2.3 m yr-1. Furthermore, a strong relationship was found between the size of the banks and the migration rates. The smaller the banks, the more rapid their migration. During the 11-year period, most banks decreased in size. As of 2014, as a manifestation of the increased distance of migration, these banks have significantly decreased in volume. In addition, they may have reached their minimum possible or allowable size.
11 h 20 - 11 h 40Uncertainty Estimates in Satellite Derived Bathymetry
Lecture Hall - Victoria Convention Centre
Richard Flemmings, TCarta Marine
By avoiding the logistical issues of conventional survey methods, Satellite Derived Bathymetry (SDB) offers great potential to map clear shallow waters quickly and efficiently. Unfortunately the remote sensing methods used for SDB generation do not lend themselves to the creation of uncertainty estimates – a vital and accepted part of conventional surveys. Without trustworthy uncertainty estimates, especially in regions devoid of any conventional ground truth bathymetry, SDB is unlikely to get much acceptance as a data source for an industry used to the results that can be obtained using conventional survey methods. TCarta Marine has considerable experience in generating SDB around the world and has recently used this experience to develop meaningful uncertainty estimates for the SDB depths produced. This paper describes the methods used by TCarta Marine to create the uncertainty estimates and explores how these may be enhanced in the future to bring SDB generation alongside conventional survey methods in terms of data trustworthiness.
11 h 40 - 11 h 45Assessing Sounding Density for a Seabed 2030 Initiative
Lecture Hall - Victoria Convention Centre
Meredith Westington, NOAA/Office of Coast Survey
In preparation for a U.S. Seabed 2030 initiative, a team from NOAA's Office of Coast Survey, the University of New Hampshire Center for Coastal and Ocean Mapping/Joint Hydrographic Center, and NOAA's National Centers for Environmental Information (NCEI) embarked on a bathymetric coverage and gap analysis. The project was designed to serve two purposes: (1) determine and compute the “mapped” and “not mapped” areas of the US EEZ and continental shelf, and (2) provide a quantitative and visual representation to support the planning of integrated coastal and ocean mapping campaign. All modern depth soundings (1960 or later) in the U.S. EEZ and adjacent continental shelf were extracted from NCEI databases and associated with a 100-m grid of the area. To perform accurate area computations in regional partitions across the US’ full EEZ and effectively manage server resources, the work was divided into approximately 170 UTM tiles, each spanning 6 degrees in longitude and 4 degrees in latitude. The results were analyzed for sounding density, and divided into categories of coverage for display in a GIS environment. This presentation will show the methods and results of this project and present some possible next steps.

11 h 45 - 11 h 50Topographic-Bathymetric Lidar Total Propagated Uncertainty Modeling
Lecture Hall - Victoria Convention Centre
Christopher Parrish, Oregon State University
Topographic-bathymetric lidar data sets collected by NOAA’s National Geodetic Survey (NGS) have been found to be highly effective for updating the National Shoreline depicted on NOAA nautical charts. Using short pulse widths, high pulse repetition rates and narrow receiver fields of view, novel topo-bathy lidar systems provide the capability to generate high-resolution data across the land-water interface. If the nearshore bathymetry from these systems can also be routinely assimilated into NOAA hydrographic processing pipelines for application to NOAA nautical charts, this will assist in addressing the current lack of data in many shallow, nearshore areas, including those shoreward of the Navigable Area Limit Line (NALL), typically defined as the 4-m depth contour. Additionally, expanding the utility of the topo-bathy lidar data within NOAA’s Office of Coast Survey (OCS) will directly support the “map once, use many times” paradigm of the Integrated Ocean and Coastal Mapping (IOCM) Program. However, a hindrance to integration of topo-bathy lidar data into OCS’s hydrographic processing workflows is the current lack of tools and procedures for quantitative analysis and reporting of the uncertainty associated with the lidar bathymetry, in accordance with the International Hydrographic Organization (IHO) S-44 Standards for Hydrographic Surveys (5th Edition). This project seeks to address this challenge by developing operational software for topo-bathy lidar total propagated uncertainty (TPU) modeling to be used in NGS. The TPU model is broken into two components: one focused on the sub-aerial (i.e., above water) portion using analytical uncertainty modeling techniques, and the second on the sub-aqueous portion, utilizing Monte Carlo ray tracing. The results of the initial tests of the TPU software on Riegl VQ-880-G topo-bathy lidar data collected by NGS in a southwest Florida project site demonstrate the utility of the tool, which is anticipated to enter operational use in NGS within the next year.
11 h 50 - 12 h 00The Future of Crowdsourced Bathymetry: Fishfinder vs Leadline
Lecture Hall - Victoria Convention Centre
Adam Reed, NOAA
Crowdsourced bathymetry data is a valuable asset for hydrographic. Crowdsourcing is capable of providing frequent data in areas susceptible to change, and in areas where traditional hydrographic survey is cost prohibitive to perform as often as needed. Yet where does crowdsourced bathymetry data fit in with the discipline of hydrographic survey and nautical charting? What are the best ways to utilize crowdsourced bathymetry data? How can we be participating in the campaign to increase contributor participation and available pathways of harvesting data? This presentation will address the current public and private sources, and upcoming initiatives to expand and improve crowdsourced bathymetry data. We will discuss outreach strategies for hydrographic organizations to increase crowdsourced participation. Finally we will explore the potential hydrographic uses of crowdsourced bathymetry, and what questions and barriers exist.

13 h 00 - 13 h 20Best Practices for Shallow Water Topo-Bathymetric Lidar Surveys
Lecture Hall - Victoria Convention Centre
Tim Webster, Applied Geomatics Research Group, Nova Scotia Community College
Topo-bathymetric lidar sensors offer a unique ability to capture the white ribbon, the zone between the land and the deeper water, where data can be challenging to acquire. The Chiroptera II system is equipped with two lasers: a 1064 nm topographic & water surface laser capable of a pulse repetition of 500 kHz and a 515 nm laser capable of a pulse repetition of 35 kHz and a RCD30 multispectral camera. This sensor is ideal for surveying the “white ribbon”, however water clarity can limit the amount of depth penetration. Additional constraints effecting the lidar sea floor returns include the reflectively of the bottom and the occurrence of submerged aquatic vegetation (SAV). We deploy real-time turbidity buoys that are connected to the internet to inform the lidar operations team on water clarity conditions. Extensive ground truthing is carried out near synchronously with the aerial survey to understand the water and seabed conditions and to map the height of SAV. In addition to updating the bathymetry of coastal areas and harbours, the intensity data from the green laser can be combined with elevation metrics (e.g. roughness) and the photography to generate benthic cover maps. The seamless elevation model are used to generate coastal hydrodynamic models. These circulation models that exploit the high resolution seamless DEM, benthic maps and height SAV as input parameters for roughness and can be used in variety of applications including: tracking the trajectory of contaminants (e.g. oil, bacteria), suitability analysis for siting new aquaculture farms, and storm surge and wave models.
13 h 20 - 13 h 40Spatial Resolution of Airborne Bathymetric Lidar: Point Density vs Light Scattering
Lecture Hall - Victoria Convention Centre
Viktor Feygels, Teledyne Optech, Inc.
To improve the resolution of airborne lidar systems at an adequate seabed mapping performance, lidar designers make efforts to increase the density of the sensed points on the sea surface. To date, the pulse repetition frequency (PRF) for topographic lidars approaches the value of 1 MHz to provide 15-20 points/m2 for typical altitudes and scan angles. The same trend is observed in bathymetric lidar development: the market offers systems with the PRF of 550kHz and the distance between the footprints of the sounding laser pulses on the water surface of the order of 15-25 cm. Specific feature of laser bathymetry is a strong scattering of the laser beam in the range of small scattering angles, which leads to widening of the sensed spots on the bottom and overlapping of neighboring footprints from the independent impulses. The effect increases with depth and seawater turbidity, and depends on the shape of the medium volume scattering function close to forward direction. Contribution of the light scattering in the water into the sensed spot size on the bottom cannot be compensated by the reduction of the sounding laser beam divergence and the receiver field-of-view angle. The Report considers quantitative estimates for the size of sensed bottom footprints for airborne bathymetric lidar for various water types depending on carrier altitude, sounding pulse divergence, and lidar receiver field-of-view. The analysis is based on “diffuse” small-angle-scattering approximation for the radiative transfer equation in the frames of “multiple forward – single backscattering” model of oceanographic lidar response signal. Application of the results to optimize the PRF for a given airborne bathymetry task and environment characteristics should account for the fact that lidar source PRF is increased at the cost of a decrease in separate emitted pulse energy and inevitable reduction of the lidar operation depth.
13 h 40 - 14 h 00Shoreline Verification Using Unmanned Aerial Systems (UAS)
Lecture Hall - Victoria Convention Centre
Andrew Orthmann, TerraSond Limited
TerraSond, a hydrographic services company based in Palmer, Alaska (USA), used several Unmanned Aerial Vehicles (UAV) to verify shoreline locations operating from a 105’ (32 m) research vessel from July through August, 2017 on a major hydrographic survey in the Gulf of Alaska. The UAV provided a rapid method for verifying historic shoreline location and features while providing greater safety for hydrographers by reducing small boat operations near shore. This paper explores the challenges and potential of this approach to shoreline mapping. Authors: Andrew Orthmann Grant Cain Thomas Newman
14 h 00 - 14 h 20Autonomous Unmanned Surface Vessel Bathymetric Survey
Lecture Hall - Victoria Convention Centre
Paul L. Donaldson, Survey Operations Coordinator/Chief Hydrographer, Leidos
In 2017, Leidos participated in both the Gulf of Mexico Unmanned Systems Operational Demonstration (GOMOD) and the Advanced Naval Technology Exercise 2017 (ANTX 2017). Leidos used the R/V Pathfinder vessel, which is the surrogate testing platform to the Sea Hunter medium displacement unmanned surface vessel (MDUSV), and performed multibeam sonar hydrographic surveys in autonomous mode. The vessel maintained COLREGs (International Regulations for Preventing Collisions at Sea) compliance reacting to both real-world and injected “interferers” to test the ability of the system to divert from the planned survey line during a COLREGS maneuver and the re-acquire the survey line once safe to do so. This paper will present the R/V Pathfinder systems, the results from the surveys, and next steps.
14 h 20 - 14 h 30Autonomous Navigation of US Nautical Charts
Lecture Hall - Victoria Convention Centre
Val Schmidt, Center for Coastal and Ocean Mapping, University of New Hampshire
Sam Reed, Center for Coastal and Ocean Mapping / University of New Hampshire
Although much interest has been given to the use of autonomous surface vehicles (ASVs) for hydrographic data collection, little thought has been given to the utility of currently available chart products for safe navigation of the ASV itself. In the United States, chart products are currently available in digital form, as both cartographic raster images of traditional paper charts and as vector representations of cartographic data, (“BSB” files and electronic nautical charts (ENCs), respectively). Here we evaluate these chart products with an eye to common methods by which artificial intelligence (AI) algorithms would likely use them. We find that the raster cartographic nature of BSB nautical charts leaves a complex interpretation problem for computers to recognize and understand their nuance. However, the BSB cartographic representation holds useful information that can be difficult to infer from electrical nautical charts, particularly when size of objects are implicitly tied to the scale of the chart. Further we find that while ENCs provide near instantaneous interpretation, the data must be reorganized for fast search. Additionally, some features, notably docks and breakwaters, are represented in the ENC in a single dimension (a line) even though they subtend a finite second dimension, forcing the AI algorithm to buffer objects to ensure safe navigation. When objects fail to have explicit measurements (for example a measured depth) encoded in the ENC, one is left to interpret their relative hazard from qualitative descriptions. This interpretation can be particularly challenging when the qualitative descriptions are referenced to the local vertical datum. Finally, the ENC’s compilation scale, when encoded, is particularly useful as it provides an implicit measure of uncertainty about the chart information, determining the granularity with which navigation choices can be made.

15 h 00 - 15 h 20Evaluating Externally Sourced Bathymetric Data for Nautical Charting Purposes
Lecture Hall - Victoria Convention Centre
Adam Reed, NOAA
International Hydrographic Standards drive the requirements for any bathymetric data utilized by hydrographic offices in their nautical chart products. However, what should hydrographic organizations do with readily available, modern survey data acquired by a non-hydrographic source? In many cases, these data may be the best available for nautical chart updates but may meet a lesser IHO accuracy standard. Failure to incorporate the best available data to nautical charts causes discrepancies with other mapping sources, and represents a dangerous choice given to the mariner. The quantity of available bathymetric data from non-hydrographic sources and sources not contracted for hydrographic survey will only continue to grow. This presentation will explore NOAA Office of Coast Survey’s initiatives and progress over the past year in expanding the breadth and capacity for utilizing externally sourced data to improve nautical charts. The primary topics will include the methods of data discovery, documentation and tracking, challenges in making the data discoverable, use cases and chartablity of data received, the results experienced by Office of Coast Survey, and the lessons learned.
15 h 20 - 15 h 40Linking Hydrographic Data Acquisition and Processing to Ocean Model Simulations
Lecture Hall - Victoria Convention Centre
Ian Church, University of New Brunswick
Numerical hydrodynamic ocean models and the hydrographic sciences are closely linked. Ocean models are capable of outputting physical oceanographic conditions, such as tides, currents and the distribution of temperature and salinity at a variety of spatial and temporal scales. To assist with model development, hydrographic survey bathymetry defines the bottom boundary of the model domain, and often nautical charts are used as a source of model coastlines and intertidal elevations. The potential exists for the development of a symbiotic relationship between the two sciences. Ocean modelling simulations require a detailed understanding of the shape and roughness of the seafloor to constrain the movement of water throughout an area but also output the physical oceanographic variables needed to process underwater acoustic data and help predict tidal elevations and current fluctuations. This paper investigates the interaction of ocean modelling and hydrographic surveying from several perspectives and examines the interdependence of both in terms of model construction and hydrographic data acquisition and processing. Three case studies are investigated in diverse oceanographic conditions, including a west coast fjord, a highly stratified estuary in the Bay of Fundy, and the Arctic. Past, present and future hydrographic survey integrations with ocean modelling are presented, ranging from estimating seafloor roughness to processing crowdsourced bathymetry data.
15 h 40 - 16 h 00Lidar Data Integration for Nautical Publication and Spatial Data Infrastructure (SDI) Workflows-Common Issues and Experiences at NOAA and CHS.
Lecture Hall - Victoria Convention Centre
Stephen Parsons, Canadian Hydrographic Service
Gretchen Imahori
Authors: Stephen Parsons, Mike Aslaksen, Gretchen Imahori, Graham Bondt, Clare McCarthy, Stephen White Over the last 10 years, enhancements to lidar sensors have encouraged the increased use of bathymetric lidar for a variety of applications. As a result, the quantity of bathymetric lidar data has increased substantially. Today, there remains an overwhelming struggle to fully integrate this data within a wide variety of data products requiring standard accuracy and attribution requirements. In the case of hydrographic office workflows, lidar data must suit current software applications used to produce Nautical Publications and is highly tied to the need to produce standard results that follow IHO standards (S-57). When lidar data enters the SDI data workflow the needs are somewhat different and are oriented around more general uses of the data, however, elements such as detailed attribution are more important. There are also many common issues that both workflows share. This paper describes the common issues and experiences that have been identified between NOAA and the CHS over the last several years and describes an overall, current approach to data integration to help better understand the needs and improvements required for an efficient and beneficial application of bathymetric lidar to a wider range of end users.
16 h 00 - 16 h 20Charlene and Automated Hydrographic Data Processing
Lecture Hall - Victoria Convention Centre
Eric Younkin, NOAA
Hydrographic data processing can be a tedious and time-consuming task, especially over large areas. NOAA field units execute a standard routine each night to generate products used for creating the next day’s plan and basic data quality control, and thus rapid and accurate processing is vital. Recognizing this need in the industry, both Teledyne CARIS and Applanix have recently released a set of tools that provide access to their core processing algorithms, providing any users with basic scripting or programming skills the ability to automate most, or all, of their data processing. NOAA has developed an open-source Python application we call Charlene, that integrates Caris Batch and Applanix POSPac Batch utilities as well as NOAA developed tools for quality control and data transfer. Charlene has been in testing and production for most of 2017, allowing NOAA field units to fully automate daily processing, thus ensuring an efficient, timely workflow. The Charlene workflow is around 10% faster than manual operations, but more importantly, requires no operator time after the initial setup and run. As a result, the hydrographer has more time to analyze data quality issues, work on existing projects, and make timely operational decisions based on the previous day’s data.

Lecture Hall - Victoria Convention Centre
Jeff Lower, IIC Technologies
From the fall of 2016 to the summer of 2017, IIC collected and processed over 10,000 sq. km of bathymetric LiDAR data and multispectral/hyperspectral imagery for the Canadian Hydrographic Service (CHS). The project included four areas (Quebec, Ontario, Nova Scotia, and Prince Edward Island). The team utilized the Optech CZMIL sensor mounted in a Piper Navajo. The project contained many challenges, including remote areas with no gasoline, nor'easter storms, snow, frigid temperatures and highly variable water conditions. This presentation will highlight the project and results, innovative technologies, as well as the many lessons learned in the process.

Lecture Hall - Victoria Convention Centre
Alison Proctor, Ocean Floor Geophysics, Inc.
Shell Ocean Discovery XPRIZE competition is aiming to push the boundaries of ocean technologies by soliciting solutions to the grand challenge of mapping our oceans. The Round One challenge in 2017 for the Shell Ocean Discovery XPRIZE was to develop a complete system that could map 100 km2 at 5 m horizontal resolution in 16 hours and produce images the elicited excitement in the general public. The designated survey area for the XPRIZE challenge could be up to 50 nautical miles offshore and operations had to be remotely coordinated from a land-based operation center. The entire mapping system must fit into a standard 40-foot shipping container. The GEBCO-NF Alumni Team is an international team working on solution towards autonomous Ocean Mapping operations. The team was initiated and led by alumni of the Nippon Foundation / GEBCO training program at the University of New Hampshire. The alumni worked closely with international partners and suppliers to develop and advance their concept created for the Shell Ocean Discovery XPRIZE. The aim of the GEBCO-NF Alumni Team was to leverage existing technology, wherever possible, and to integrate them to achieve the competition requirements. Their strategic approach was to develop strong partnerships with technology and services providers to augment the hardware, integration and software needs of the team. The GEBCO-NF Alumni team conceived a two-system, Autonomous Underwater Vehicle (AUV) and Uncrewed Surface Vehicle (USV), concept to autonomously map the seafloor in a wide variety of ocean environments. The AUV-USV idea will lead to more efficient, safer and cost-effective seafloor mapping operations. The Team chose the industry leading HUGIN AUV developed by Kongsberg Maritime for this project, specifically Ocean Floor Geophysics’ HUGIN AUV Chercheur. This vehicle is equipped with a Kongsberg EM2040 Multibeam and a Kongsberg HISAS 1032, a deep-water interferometric synthetic aperture sonar, that can collect bathymetric and imagery data

10 h 30 - 11 h 00Why Did the Clipper Clip It? – The Clipper Adventurer Grounding
Lecture Hall - Victoria Convention Centre
Bruce Calderbank, Hydrographic Survey Consultants Intl.
There seems to be a general perception that the increasingly ice-free Arctic waterways are safe for passage, when significant areas have not been adequately surveyed. However, as of 2011, less than 10% of Arctic waters had been surveyed to modern standards. On 27 August 2010, the expedition cruise ship Clipper Adventurer went aground at 13.9 knots on a rock shoal whilst travelling in a poorly charted area of Coronation Gulf, Nunavut. The presentation reviews the background and the geomatics issues related to the grounding. There were a variety of geomatics facts that do not appear to have been addressed in either the 2012 Transport Safety Board marine investigation report nor in the 2016 Federal Court case, which are covered in the presentation. = > This case is currently under appeal and the presentation will be updated to allow for that new information. The associated paper is 33 pages long at this time.

11 h 20 - 11 h 40Canada's Marine Spatial Data Infrastructure and Marine Cadastre application
Lecture Hall - Victoria Convention Centre
Jose M'Bala, Natural Resources Canada
The Canadian Hydrographic Service (DFO) and the Surveyor General branch (NRCan) have lately worked together in the development of a Marine Spatial Data Infrastructure (MSDI) pilot project prototype, with a Marine Cadastre application. The primary focus was on three areas of interests: - The Bay of Fundy (East), - The Dickson entrance (West), and - The Beaufort Sea (North). The vision of the CHS Marine Spatial Data Infrastructure (MSDI) is to design and implement a framework of geographic data, metadata, users and tools that are interactively connected in order to use spatial data in an efficient and flexible way. The intent for the Surveyor General Branch for a marine cadastre is to develop an integrated system of registries, fundamental for a systematic public recording of all recognised legal rights, restrictions, and responsibilities; and aiming at providing a legal foundation for the management of Canada’s oceans and more certainty for industry and capital investment. The MSDI and its applications, is developed to show case and validate an all-inclusive Spatial Data Infrastructure (SDI) solution which focuses on marine geospatial domain and activities.
11 h 40 - 12 h 00Offshore Infrastructure Surveys – Preliminary Findings
Lecture Hall - Victoria Convention Centre
Bruce Calderbank, Hydrographic Survey Consultants Intl.
The research was carried out to support the Association of Canada Lands Surveyors (ACLS) Offshore Committee’s interests in offshore infrastructure surveys (OIS) within and without Canada’s twelve (12) nautical mile limit. The research focused particularly on the practices with regard to offshore pipelines, flowlines, umbilicals, subsea structures, and communication and power cables. In addition, the report examined how such spatial information is gathered, managed and shared. Currently, this information is generally held by the offshore infrastructure owners and only shared if required. In addition, the standard of the surveys carried out were not uniform, as they are mostly driven by client specific issues. The presentation will cover OIS in Nova Scotia and Prince Edward Island with some references to practices in British Columbia and the UK.

While GPS is considered a mature technology to most people, a great deal of research continues in the fields of GNSS-based positioning, navigation and timing (PNT).  GNSS constellations are growing and evolving, bringing benefits from new signals and more measurements, and challenges from a host of measurements biases that must be managed.  GNSS measurement processing has advanced to provide new and improved solutions, such as Precise Point Positioning (PPP) and more recent advances of this approach.  The development of more capable low-cost hardware is being driven by commercial applications to provide greater accuracy and precision.  The result will be near-term opportunities for smaller, cheaper, autonomous solutions in hydrographic applications.

Lecture Hall - Victoria Convention Centre
Harold Elliot Orlinsky, General Manager, Hypack
Bridge scour is the removal of sand or material around bridge piles, caused by moving water. Over the past 40 years, there have been more than 1500 bridge failures in the US, with nearly 60% caused by bridge scouring, with costs in the millions of dollars. Early detection of this problem allow for remediation and the prevention of potential bridge failure. It is estimated that the costs of a bridge failure is over 5 times the cost for remediation. This paper will show how susceptible bridge pilings are to swift moving water, and a case study of using HYPACK for the monitoring of a bridge in North Carolina.
15 h 20 - 15 h 40Autonomous vehicles: The Canadian Hydrographic Service Journey…
Lecture Hall - Victoria Convention Centre
Roger Cote, Canadian Hydrographic Service
Authors: Roger Côté, Annie Biron, Ghislain Bouillon and Éric Lebel The Canadian Hydrographic Service (CHS) has entered in a positive and productive era with a significant increase of resources. This is an outstanding opportunity for CHS to review its operational model, especially in the acquisition and management of source data. The use of new technologies, crowd source information and new methodologies is a trend in the international hydrographic community and, as always, the CHS is willing to play a major role in the development and implementation of these new assets. Hydrographic Organizations (HO’s) traditionally use acoustic sonar systems mounted on various platforms and manoeuvered by experienced coxswains and/or officers to collect and disseminate source data internally in order to produce nautical products. This has proven to be very efficient but it implies that hydrographers must operate systems and sometimes put themselves at risk in harsh environments. New technologies and techniques like LiDAR, autonomous vehicles and Satellite Derived Bathymetry (SDB) will enable HO’s to choose in a broader range of technologies to obtain data without putting their staffs at risk and do more with less. CHS recently bought 2 AHSV’s (Autonomous Hydrographic Surface Vehicles) and converted one survey launch to make it autonomous (named: Autonomous Hydrographic Survey Launch (AHSL)). They are equipped with complete multibeam and INS systems. CHS is planning to use them this summer and define an operational model and the limitation, and define how they will be included in CHS current operations. This paper will give you an overview of the procurement process, the trials, the processing, the results and the quality of the data obtained with those systems. You’ll discover that being first is not always an easy process, but the results worth the efforts.

Ted Cain, Lead Hydrogropher, Public Services & Procurement Canada
Law of the Sea is much in the news over that last number of months/years as a result of legal and political controversies in the South China Sea and to a lesser extent in the Arctic. In the South China Sea, the geographic/legal issue involve first, tiny island/rock features in the South China Sea and the second, claims by China to ocean space based on history. The first thing about the rock/island features is that numerous of the local States claim ownership of the features and then there is the legal question as to whether a particular feature is a rock [entitled to a 12- nm territorial sea] or an island [entitled to a 200 nm resource jurisdictional zone.] Some though not all of this was “resolved” by a Tribunal in 2015-2016. Not directly related to the South China Sea is the Arctic. With the exception of Hans Island there are no territorial disputes. There are, however, overlapping 200 nm zone claims between Canada and both Denmark and the United States. And there is the pesky navigational rights “legal” matter between the US and Canada regarding the Northwest Passage. A State’s offshore jurisdiction is not necessarily restricted to 200 NM … where the physical facts allow a State has jurisdiction over the continental shelf adjacent to its coast. Hence, Canada has exclusive jurisdiction over the potential oil and gas located well beyond 200 nm due east of St John’s. And in the Arctic … we do not know yet just how far Canada’s shelf beyond 200 nm extends, but we have an excellent idea of where Russia and Denmark think the their continental shelves are in the Arctic.

Kelvin Kopeck, Terra Remote Sensing Inc.
ROV’s serve an important role in marine construction surveying....to relay important information that is unattainable otherwise. For marine power cable or pipe projects the ROV is generally just one tool of a larger spread of remote sensing devices. If the project is planned correctly these can be used to meet project goals in a safe, timely, and cost affective manner. This discussion will focus on how these tools are utilized to address primary cable-project concerns, objectives, and solutions to typical (and atypical) project requirements, including responding to faulted cables, route assessment and mapping, installation monitoring, post lay inspection, and drawing production.

Parcels of Land can be defined by both rectilinear and/or natural boundaries. Natural boundaries can be of any natural feature, but generally describe water boundaries. These boundaries can be mapped using "on the ground" survey methods (conventional ties, GNSS ties, etc.) or using remote methodology using aerial photography. The use of photography obtained by drones is becoming more widespread in topographic surveys and can be similarly used to determine natural boundaries with checks using conventional methods.

Lecture Hall - Victoria Convention Centre
Matthew Wilson, QPS
The Quality Positioning Services (QPS) Nautical Charting Workflow is the only one in the industry that fully encompasses the journey of a ping from the surveyor to the pilot. There is tremendous advantage in the fully-integrated solution, as it allows for the preservation of data formats throughout the entire workflow, and eliminates errors associated with data conversion and metadata loss. The QPS Nautical Charting Workflow is built on streamlining processes and efficiency: • Actual pings are captured in the integrated navigation software QINSy, built on a philosophy of real-time corrections and quality assurance to ensure high data quality capture. • Acquisition projects open directly in Qimera, a processing software with intuitive, guided workflows, and designed to automate mundane tasks, thus common, human errors are eliminated. • Survey data migrates seamlessly into Fledermaus, a visualization software specializing in 4D geo-spatial analysis, and it promotes above all clear communication and presentation of data. • Soundings and contours are extracted automatically from gridded bathymetry in Qarto, the ENC production software, built for a rapid turnaround—some survey-to-ENC workflows have been measured in hours. • Updated charts go live in Qastor, a precise navigation software for piloting with Under Keel Clearance (UKC) and vessel docking capability, which can be further interfaced with AIS and meteorological data for real-time updates. Further process efficiency is gained by real-time processing in QINSy, which allows for unprecedented decision-making capabilities for surveyors while they are still in the field. While there are great benefits to the fully-integrated solution, the workflow components are also perfectly modular for the utmost client flexibility. The Port of Rotterdam, an early-adopter of the QPS Nautical Charting Workflow components, is a prime example, and is presented as a case study. The advantages of the solution are shown in terms of timeliness in the ping-to-pilot workflow and rapid product turnaround.
08 h 30 - 08 h 50eTrac's Evaluation of Qimera: Accomplishing the NOAA Workflow
Lecture Hall - Victoria Convention Centre
David Neff, eTrac Inc.
eTrac’s 2017 NOAA task orders in the state of Florida cover over 100 miles, from Sarasota to Naples, with area coverage requirements prioritized per NOAA’s hydrographic health model. These include inlets, ferry routes, and over 100 feature investigations, which are particularly important after the passage of Hurricane Irma. eTrac, with their considerable resources and skilled personnel, is well-suited to handle such a project, and at the same time prides itself in their ability to be on the leading edge of new tools and capabilities. QPS Qimera emphasizes above all a clean and streamlined workflow, one that minimizes the error-prone human tasks that traditionally have been required in hydrographic data processing. With eTrac operating three survey vessels daily, each with dual-head multibeam echo sounders, plus with the considerable feature requirements, there is excellent opportunity to evaluate Qimera’s data throughput capabilities, dynamic workflows, and finally, its latest functionality—S-57 feature management. Additionally, eTrac showcases the benefit of QPS QINSy for acquisition—with real-time integration capabilities and seamless project migration to Qimera, there is potential for significant gains in efficiency. Qimera will be evaluated during this project, with particular attention paid to the rapid data processing turnaround that is required by eTrac to ensure quality standards per NOAA specifications. Furthermore, the benefits of Qimera’s processing state management and guided workflows for the eTrac personnel on-scene with varying experience levels will be assessed. Lastly, Qimera’s S-57 capabilities—built with new, innovative methodology, in-spirit with the Qimera philosophy of removing human error from what is traditionally a quite tedious process—will be introduced. Both advantages and lessons learned will be included, and the benefits measurably delivered by Qimera—for eTrac and NOAA alike—will be presented.
08 h 50 - 09 h 10Benefits and Impacts to Nautical Charting by Adopting a New Reference Frame
Lecture Hall - Victoria Convention Centre
Neil Weston, NOAA
NOAA’s Office of Coast Survey (OCS) is responsible for maintaining the nautical charts for the nation and most of the publications for the coasts and Great Lakes. Currently there are over 1000 nautical charts in vector and raster format and roughly 95,000 miles of shoreline that OCS is responsible for. Providing accurate metadata and geospatial information on man-made features, depths, rocks, aids and dangers to navigation, and vessel traffic separation schemes, are paramount for the agency and require several strategic approaches for being successful. As NOAA and OCS continue the migration from paper to electronic charts, building seamless databases that distribute accurate navigational products and services requires proper identification of geospatial information and adoption of the most accurate reference frame and datum. In 2022 the National Geodetic Survey, NOAA will be replacing the current North American Datum of 1983 (NAD 83) with a more accurate one that is geocentric and derived using Global Navigation Satellite Systems (GNSS) technology. One significant difference between the two frames is the origin of NAD 83 is offset from the origin of the new frame by approximately 2.2 m. Adoption of the new frame will therefore change the horizontal and vertical components of all NAD 83 positions in the United States and Canada and the magnitude of change to each component is dependent on the geographic location on the Earth. This paper will explore the steps necessary to adopt a new reference frame and datum as well as highlighting the possible impacts that may affect the geospatial foundation of all nautical charts.

Bathymetric Surfaces to Charted Features: Defining a Smooth Path to Safety Stuart A. MacGillivray (Senior Software Developer) Teledyne CARIS, Fredericton stuart.macgillivray@teledyne.com Karen Cove (Product Manager) Presenter Teledyne CARIS, Fredericton karen.cove@teledyne.com Efficiently generating smooth contours for navigation from bathymetric surfaces remains a challenge. While the definition of new and innovative products like the S-102 Bathymetric Surface implies that the future may provide new ways to deliver safe, high-quality data to mariners, the current paradigm relies on contours. In addition to the traditional and highly generalized ENC delivery of this information, we also have the opportunity to produce complementary high-resolution overlays in sensitive and high-traffic areas. While these bathymetric data overlays (bENCs) provide an opportunity to provide denser, more accurate, and timely information to the mariner, the problems in constructing smooth contours are compounded by the volume of data to analyze and the number of geometries to construct. In order to meet these requirements there is a need for tools that address the hydrographic constraints of safety, legibility, topology and waterbody morphology. Other drivers are the need to quickly and automatically produce results on high volume datasets and to reduce the time spent by hydrographers on manual validation. Scalability, performance and automation are key drivers for success. Two distinct approaches have been considered and will be presented. Both strategies make use of established research combined with original revisions. The first is based on the idea of using a consistent smoothed surface model. This model can then be used to generate contours that will be smoother, self-consistent, topologically correct, and safe with respect to the original data. The second approach is direct contour smoothing using a method referred to as energy-minimizing snakes. This is paired with resolving conflicts in contour sets and new approaches to curvature gradients to optimize results.

10 h 30 - 10 h 50A Design for a Trusted Community Bathymetry System
Lecture Hall - Victoria Convention Centre
Brian Calder, CCOM/JHC University of New Hampshire
Crowd-sourced bathymetry (CSB) has received a significant amount of attention in recent years. Although increasing amounts of data are being collected, attributed, and archived, finding a route to the nautical chart has been problematic. Partially, this is due to a lack of formal means to represent data quality on the chart, but is mostly due to lack of qualifying information for the data. CSB efforts generally suffer from a lack of calibration, leading to time-varying and uncontrolled vertical offsets. Assumptions that these issues can be resolved by having a sufficient number of independent observations (the "wisdom of crowds'" argument) are often frustrated by basic physical limitations: the ocean is big, and ships are (relatively) small. Except in limited circumstances, or specific areas, the chances of having any repeated measurements are vanishingly small. As an alternative to the collection of unqualified (CSB) data, we propose a data collection system which, by construction, provides sufficient guarantees of data quality to allow the measurements to be considered for hydrographic use. We call this method Trusted Community Bathymetry (TCB). A TCB system resolves many CSB issues through significantly improved vertical positioning. High-accuracy, high-precision post-processed 3D GNSS solutions allow for the estimation of vertical offsets so that autonomous calibration is possible; ellipsoid-referenced depths obviate the need to apply tidal corrections to the data. Given a known offset, similar techniques can be used to autonomously establish calibration sites. TCB systems can also cross-calibrate CSB data. We demonstrate these ideas using a prototype TCB system developed by SeaID Ltd., which combines a NMEA data logger with a GNSS system. By comparison with survey-grade GNSS and INS systems, we demonstrate how to establish the vertical offset calibration in a system, and the construction of a calibration site. We also qualify the fundamental performance of the prototype system.
10 h 50 - 11 h 10Radiometric Complications in Multibeam Multispectral Backscatter Data Due to Different Transmission Approaches, Solution and Results
Lecture Hall - Victoria Convention Centre
Anand Hiroji, Center for Coastal and Ocean Mapping/Joint Hydrographic Center, University of New Hampshire
As an essential prerequisite for utilizing multibeam backscatter data for seafloor classification, proper adjustment to account for the radiation pattern of the transmitter is required. The radiation pattern is a sonar specific property and any method that extract the radiation pattern should not be influenced by the seafloor or ocean conditions. To satisfy this need the Geometric method to extract radiation pattern was previously developed and presented (CHC2016) by the authors. The method was then applied to the multispectral analysis (US Hydro 2017) for the systems (EM710 and EM2040) whose transmit sectors were not compensated for vessel roll. An additional complication, however, exists for those sonars that do have roll stabilized transmit sectors (EM302 and EM122). In this case, the Geometric method can only utilize the grazing angle variations. In this paper, an approach to extract radiation pattern using Geometric method is demonstrated. Practical examples of the different radiation pattern over-print are presented from recent RV Celtic Explorer cruise in South Celtic Sea during which a low-frequency EM302 was simultaneously operating along with high frequency EM2040. The radiation patterns for both EM2040 and EM302 are successfully extracted and then properly corrected from the backscatter data. The corrected backscatter data was then used for multispectral data analysis. The multispectral angular response curves and backscatter mosaics are presented. Collected bottom samples are used to interpret the multispectral backscatter results.
11 h 10 - 11 h 30Quantifying the Impact of Internal Wave Activity on Multibeam Bathymetry
Lecture Hall - Victoria Convention Centre
John Hughes Clarke, UNH
Imperfect compensation for the refracted ray path has long been recognized as a major source of error for oblique multibeam soundings. Given the discrete nature of sound speed profiling methods, the scale of the refraction-related error can be attributed to a combination of both the vertical shifting of the veloclines as well as their local slope. To quantify the relative scale of these two contributors, a 3D ray trace model output is compared to field results from a broad range of velocline oscillation (internal wave) scales. The example data is from two weeks of multibeam operations in the summertime Celtic Sea. The region is characterized by a very strong thermocline (~20 m/s step) which is routinely perturbed through baroclinic shear resulting from tidal flow over upstanding seabed relief (banks). The net result is a wide spectrum of internal wave activity, with amplitudes ranging from 1-30 m and wavelengths ranging from 100 m to 10 km. As the seafloor morphology is generally so smooth, the signature of refraction related artefacts can clearly be distinguished and measured. The data are corrected using an underway profiling instrument (MVP-200) operated at ~ 30 minute intervals, corresponding to about 7 km spacing. Underway multi-frequency acoustic imaging from both single beams (EK-60, 18, 38, 120 kHz) and multibeams (EM2040 and EM302) are used to define the wavelengths, amplitudes and azimuths of the internal wave activity. The observed scale of undulations are run through the 3D model at various azimuths relative to the survey vessel track. The scale of the vertical depth anomalies are calculated with respect to the perturbation geometry. The impact of the higher density sound speed profiling is assessed.
11 h 30 - 11 h 50Improved Sound Speed Control Through Remotely Detecting Thermocline Undulations
Lecture Hall - Victoria Convention Centre
Jose Cordero, Center for Coastal and Ocean Mapping / UNH
Internal waves are a common phenomena associated with stratification developed in summer-time shallow tidal seas. They result in very rapid undulations in the main velocline which, if not accounted for, will result in significant refraction errors in multibeam data. Mechanical sound speed profiling, both static and mobile, cannot sample this structure adequately. Thus an alternate means of detecting and accounting for that variability is needed. Within the oceanographic community, it has long been recognized that a distinct volume scattering layer is often associated with major oceanographic boundaries. This reflects a combination of temperature/salinity microstructure or zooplankton around the pycnocline depth. Taking advantage of that, several weeks of multibeam survey on the Irish continental shelf were undertaken during which multispectral acoustic scattering data from an EK60 echo sounder was acquired together with an MVP profiler deployed every ~ ½ hour. A directional filter algorithm has been developed to try and extract the location and undulations of the scattering layer(s) from the EK60 echograms. The extracted layer depth was then compared to the velocline found in each of the discrete MVP profiles. Variability in the correlation between the extracted layer and the actual peak velocline is used to assess the accuracy of the method. Where it is deemed successful, the observed sound speed structure can then be shifted on a ping by ping basis to try and emulate the internal wave activity.This way, ray tracing would be possible using a unique profile for every ping. The results of this approach are presented, particularly focusing on periods when the correlation was poorer. This was noted to occur at dawn and dusk due to the diurnal plankton migration. The Celtic Sea is recognized as an area of a relatively strong thermocline, and thus this method may be less useful in more complex stratification conditions.

Comparing the Automatic Boresight Calibration against the Patch Test Eli Leblanc (Geomatics Software Developer, Eli.Leblanc@Teledyne.com )1 Burns Foster (Product Manager, Burns.Foster@Teledyne.com )1 1Teledyne CARIS, 115 Waggoners Lane, Fredericton, NB, CANADA, E3B 2L4 Abstract Although it has been used for almost 2 decades, the traditional patch-test to estimate the boresight angles between IMU and sonar has several drawbacks related, among others, to its subjectivity, cost, and the inability to deal with the correlation between roll, pitch and yaw. The motivation behind the new Multibeam-IMU Boresight Automatic Calibration (MIBAC, CIDCO) algorithm was to design a new boresight calibration method that addresses these concerns through a systematic approach to boresight determination. This presentation will introduce a practical integration of the MIBAC tool, and discuss the results and performance in comparison with the traditional patch-test approach.

Lecture Hall - Victoria Convention Centre
Neil Dangerfield, Physical Scientist, Canadian Hydrographic Service
A comparison of the bathymetry reduced using the vessel’s satellite-derived vertical position and the Hydrographic Vertical Separation model (HyVSEPs) to traditionally derived water level values indicates the model’s performance to accurately predict separation values. During the 2016/2017 Pacific region field seasons, statistics were generated for multiple sites in a variety of tidal regimes throughout the British Columbia coast. In this study, we investigate the data to evaluate model accuracy and suggest improvements that will adjust the model accuracy in future iterations.
13 h 20 - 13 h 40Utilization of U.S. Geodetic Service coastal water level gauges in Mississippi to check VDatum tidal datum to NAD83 vertical separations
Lecture Hall - Victoria Convention Centre
Dr. David Wells, President, HydroMetrica Limited
The US National Oceanic and Atmospheric Administration has a Vertical Datum Transformation tool (VDatum) that allows for conversions between tidal, ellipsoid and orthometric vertical datums. One important application is allowing for hydrographic surveying to the ellipsoid and using the VDatum tool to reduce the soundings to Mean Lower Low Water (MLLW). However, in southeastern Louisiana and western Mississippi, VDatum errors have been found by NOAA to be 20-50 cm. These errors cannot be absorbed by the IHO vertical uncertainty budget for special order through order 1b. USGS water level gauges provide an additional source of water level information in the region, which can be utilized to check VDatum results. These gauges report water levels with respect to gauge zero or NGVD88. In order to utilize these gauges for tidal datum to ellipsoid separation, static GNSS surveys have to be conducted for the USGS gauges and tidal datum transfers (using Modified Range Ratio method) from a NOAA tide gauge have to be performed. We report on the results from performing these analyses on a USGS gauge at the mouth of the Pearl River in Mississippi, using the NOAA tide gauge at Bay Waveland, Mississippi as the control gauge, and compare the results to those from VDatum.

Lecture Hall - Victoria Convention Centre
Patrick McNeill, UNB
The Ocean Mapping Group has been involved with collecting multibeam bathymetry and oceanography data in the Lower Saint John River and Port of Saint John since the late 1990s. This area is characterized by a complex estuary where the Saint John River meets the large tides from the Bay of Fundy in the Port of Saint John. The bathymetry was collected using multiple vessels in small projects, by different groups, and is referenced to multiple different vertical datums. The goal of the project was to create a seamless bathymetric surface with a common datum and resolution for use in a local high-resolution ocean modelling simulation. To achieve this goal, issues relating the age of the datasets, collection with multiple vessels and sensors, and combining datasets referenced to both river and chart datum had to be overcome. This project involved combining, processing, and cleaning these datasets while reducing them to a common vertical datum to create bathymetric surface products. These surface products and related oceanography data were then integrated into an online web mapping application for viewing and dissemination.
14 h 00 - 14 h 20MS-PAC: Multibeam System Automatic Parameter Calibration
Lecture Hall - Victoria Convention Centre
Nicolas Seube, CIDCO
The aim of this paper is to present some recent results from a research project conducted by the CIDCO aiming to design new procedures and associated adjustment methods for automated calibration of MBES parameters. This research is done in collaboration with ENSTA Bretagne (France) and with the support of the SHOM (France). Three classes of methods have been designed: The first one, called MIBAC (MultiBeam IMU Automatic Boresight Calibration) is a fully automated method for calibrating the boresight between an IMU (or an INS) and a MBES. In addition to the calculation of boresight angles, the system provides boresight precision through a statistical analysis of error residuals. The second one, called MILAC (MultiBeam IMU Latency Automatic Calibration) is able to determine the IMU-MBES residual latency from a MBES data set with high accuracy and precision. This method can also detect the presence of time-stamping issues in quasi real-time. The third one, called LAAC (Lever Arm Automatic Calibration) is a tool devoted to the calibration of lever arms between the survey vessel position reference point and the acoustic center of a MBES. Like MILAC, this algorithm is capable of detecting lever-arm variations in quasi real-time. The three classes of methods will be illustrated by numerical results from a series of data sets from CHS, NOAA, SHOM, CIDCO and BSH.

Lecture Hall - Victoria Convention Centre
Yun-ta Teng, CDR, Chief of Underwater Environment Section, Naval Meteorological and Oceanographic Office
February 1st, 2016, one Taiwan Coast Guard patrol vehicle with 2 officers dropped in Taipei Harbor. Taiwan government deployed 5 different groups with hundreds people but spent a week to find the bodies. Even though the searching area just located in the harbor, the weather condition and instruments affected the schedule of search and rescue(SAR). Therefore, Naval Meteorological and Oceanographic Office, R.O.C.(NMOO) started to design a Vessel-Based with a pole mount Tritech Starfish 452F Sidescan(op. freq. 450 kHz), Blueview BV5000(op. freq. 2.25MHz), and VideoRay Scout(ROV) as a Rapidly Estimated SAR mode of shallow water. In a very limited underwater visibility of the harbor, the survey mode provides not only rapidly map in high resolution and wide range images but also detect the detailed 3D shape point clouds. By rapidly surveying a shallow water or harbor area, this combination of vessel-based acoustic instruments makes SAR and mapping more feasible, efficient, and desirable.
14 h 30 - 15 h 30Closing Keynote - FROM JUAN DE FUCA TO THE SALISH SEA: VOYAGING THE WATERWAY OF FORGOTTEN DREAMS PAST AND PRESENT
Lecture Hall - Victoria Convention Centre
Barry Gough
From the vantage point of any one of the communities, settler or indigenous, that are situated by this fabled waterway, bays and estuaries we can imagine the passage of the millennia and of the centuries, particularly the last five hundred years. These are waters of legend, bounded by islands and continent, and they are seas of international rivalry now defined by international boundaries and safe shipping lanes. Beginning with Juan de Fuca in 1592 a parade of ships form -- one after another -- a bright spectacle of memory, right down to warships transiting Arctic waters. So many great ships have plowed furrows in these waters, forming in a way a microcosm of world maritime history. In late years the Salish Sea had become a new designation, embracing other names and giving a new identity to these waters, one that represents the resilient revival of First Nations and Indian nations on both sides of the border. Barry Gough will tell the larger tale, the inclusive one, that brings together and touches on the diversity of this environment, at the same time commenting on how international rivalries and present-day security problems have made a potentially unitary sea -- the Salish Sea -- a dream rather than a reality. Then again, this is just another chapter in the always incomplete book Voyages in the Waterway of Forgotten Dreams.
