Canadian Hydrographic Service Grows Its USV Fleet

The Canadian Hydrographic Service (CHS) has taken delivery of two additional autonomous unmanned surface vehicles (USVs), bringing its fleet to four systems.The 2.5-meter USVs, built and delivered by Florida based SeaRobotics Corporation, are complete hydrographic systems including multibeam echo sounders, support sensors, cast winches, deployment carts and road trailers.The SeaRobotics USVs are being deployed across Canada supported by regional training performed by SeaRobotics. CHS, part of Fisheries and Oceans Canada, has completed the first year of operation and the analysis of the efficiency and

"It is a privilege to watch traditional means and modern technologies come together to create a deeper understanding of the Arctic and our Canadian identity.”   The models were printed from the multibeam sonar data collected by Fisheries and Oceans Canada’s Canadian Hydrographic Service. The bathymetric measurements were processed in seafloor mapping software created by the New Brunswick-based company CARIS and subsequently exported for use in a 3D printer provided by the Calgary-based non-profit TECTERRA.   The high precision models are scaled representations

systems,” he said. He explained that multi-beam systems occurred in the very late 70s and early 80s and in 90s became more mainstream. “Pioneering work was done through a few key research institutes. Bedford Institute of Oceanography (BIO in Halifax) being one of them. The Canadian Hydrographic Service did a lot of work with early multi-beam systems plus there were groups in the U.S. and France as well,” he said. In the late 90s multi-beam systems became more sophisticated in the detail they reflected with the use of a number of echo sounders measuring the returns from multiple

CHS Contracts Fugro for Hydrographic Services

Fugro has been awarded a Supply Arrangement by the Canadian Hydrographic Service (CHS) to provide vessel based hydrographic survey services. Under this contract CHS will procure hydrographic surveys as needed, anywhere in Canada, to enhance its capacity for data acquisition and processing in support of its nautical charting program.   Hydrographic survey data from ports, harbors, nearshore and offshore regions will be acquired and processed using Fugro’s vessels, equipment and personnel. The resulting data will be used by CHS ultimately to update its nautical charts.   This Supply

Canada to Build 7 New Survey Vessels

;s government to build seven new hydrographic survey vessels   Canadian Minister of Fisheries, Oceans and the Canadian Coast Guard, Hunter Tootoo, announced that Kanter Marine Inc. of St. Thomas, Ontario is the winning bidder for the procurement of seven new survey vessels for the Canadian Hydrographic Service to support the seabed surveying and charting of Canada’s navigable waters.   The $5.3 million investment will go toward customized hydrographic survey vessels that will be outfitted with permanent state-of-the-art multibeam sonar systems to help the Canadian Hydrographic

This year, the Royal Canadian Navy (RCN) and Defence Research & Development Canada (DRDC) will lend their expertise and enthusiasm to the project, which also includes the Arctic Research Foundation, the Government of Nunavut, Canadian Hydrographic Service, Canadian Coast Guard, the Canadian Ice Service, and Canadian Space Agency. The Parks Canada-led survey team will conduct the underwater search from aboard the Arctic Research Foundation's Research Vessel Martin Bergmann for the full 6 weeks or so, and will be further supported during

. “With rapidCAST, we have stripped away the compromises to offer advanced automated profiling, while still offering the convenience, mobilization benefits, and great efficiency savings afforded by a compact system.”    After testing the rapidCAST prototype, the Canadian Hydrographic Service was the first to install a rapidCAST system on a survey vessel, the CCGS Frederick G. Creed, for surveys in the Gulf of St-Lawrence and off the east coast of Canada. A CTD profiler option is expected later in 2015

NOAA’s Lake Level Viewer Aids Great Lakes Community Planning

Lakes water levels are continuously monitored by U.S. and Canadian agencies in the region through a binational partnership. NOAA’s Great Lakes Environmental Research Laboratory, the National Ocean Service’s Center for Operational Oceanographic Products and Services and the Canadian Hydrographic Service have been tracking Great Lakes water levels over a number of years. The annual rise and fall cycle of the Lakes’ water levels can be seen online for particular time periods beginning in 1917 via the Great Lakes Water Level Dashboard. Over the past decade there has been a steady

The data to produce these highly accurate, 3D-representations of the wreck as it stands on the seabed were collected in September by the Canadian Hydrographic Service (Department of Fisheries and Ocean) concurrently to Parks Canada's dive operations. There have been six major Parks Canada-led searches for the lost Franklin Expedition ships since 2008, covering many hundreds of square kilometers of the Arctic seabed. The initial discovery of a

Fugro to Conduct Airborne Lidar Bathymetry Suveys in Canada

Fugro has been awarded new task orders by the Canadian Hydrographic Service (CHS) to conduct airborne LiDAR bathymetry (ALB) surveys in Eastern and Central Canada. The task orders, which have been issued under a supply arrangement Fugro holds with the CHS, are in support of their nautical charting programmes and involve the survey of multiple sites along the coasts of Quebec, Newfoundland and Labrador, Prince Edward Island, Nova Scotia and Central Canada.   Fugro’s ALB systems will be used to acquire hydrographic survey data and seabed imagery in shallow coastal waters, where the acquisitio
