5th Trans-Atlantic seabed mapping survey


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 chronical the mission. Follow along here 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.

The CCGS Louis S. ST-Laurent took a small break from transiting across the Atlantic Ocean yesterday. On July 27th at approximately 21:00 UTC we had arrived at the location of several underwater volcanoes discovered during the Galway 2015 transit.

The Louis St Laurent is now more than half way through its 11 day journey. Since the vessel left the dock at the Bedford Institute of Oceanography (BIO) in Dartmouth, Nova Scotia it has travelled over 1600 nautical miles.

Today, members of the Galway team had the opportunity to leave the CCGS Louis S. St-Laurent for 15 minutes, but we weren’t going ashore. Instead we took to the sky in one of the two helicopters onboard.

As a rookie aka “Greenhorn”of the Galway 2016 Expedition team, one of the first things that I wondered about before our departure was what life on board the CCGS Louis S. St-Laurent would be like.
