5th Trans-Atlantic Seabed Mapping Survey

On July 22, 2016, the Atlantic Ocean Research Alliance is launching the 5th Trans-Atlantic seabed mapping survey. These surveys support the Galway Statement on Atlantic Ocean Cooperation, the goals of which are to join resources of its three signatories to better understand the North Atlantic Ocean, to promote sustainable management of its resources, and to promote citizens’ understanding of the Atlantic through ocean literacy.

The expedition, which will take place from July 22 to August 2 on board the Canadian Coast Guard Ship Louis S. St-Laurent, will map the seafloor between Halifax, Nova Scotia, Canada and Tromso, Norway. The Science Team will be led by Paola Travaglini of Fisheries and Oceans Canada’s Hydrographic Service. The team will use state-of-the-art deep-water multibeam sonar technology to survey the seabed, and study the physical characteristics of the seafloor as well as other oceanographic data such as temperature, and salinity to better characterize little known areas of the North Atlantic Ocean and build on the work done in July 2015.


Participation will include Fisheries and Oceans Canada's Hydrographic Service, the University of New Hampshire’s Center for Coastal and Ocean Mapping Joint Hydrographic Center and the Fisheries and Marine Institute of Memorial University of Newfoundland. Students and early career scientists representing Canada and the United States sailing on board on board CCGS Louis S. St-Laurent are writing daily web logs to chronicle the mission which will be available on the blog section of the AORA website. Follow along to read about updates and reflections on their experiences, the science, technology, and other elements of the expedition as we continue to celebrate our shared Atlantic resource.
