Nova Scotia innovation put to work ‑ Locally‑made ingenuity goes to sea

Posted by Media Centre on April 20, 2017 in News

(Halifax, NS) – Three made-in-Nova Scotia approaches to ocean science will be used during an upcoming voyage to study the impacts of climate change on the Northwest Atlantic, sailing from St. John’s, NL to Galway, Ireland onboard the Irish research vessel the Celtic Explorer.

The research is a GO-SHIP (Global Ocean Ship-based Hydrographic Investigations Program) expedition being led by the Marine Institute of Galway, a partner of the Dalhousie University-hosted Ocean Frontier Institute which was established in the fall of 2016 through a $220 million, multi-year program funded by the Government of Canada and various private and public sector organizations.

OFI partners from Dalhousie University, the GEOMAR Helmholtz Centre for Ocean Research, Fisheries and Oceans Canada and Woods Hole Oceanographic Institution are also participating in the research voyage. Five of the scientists that will work onboard the Celtic Explorer are from Dalhousie University.

The locally-developed equipment being used during the research voyage is:

A mobile laboratory constructed by CTS Container Ltd. of Dartmouth, NS

The Celtic Explorer cruise marks the maiden voyage for this oceanography laboratory, a 20-foot long container designed to withstand the extremely rough weather and wave conditions of the Northwest Atlantic. The mobile lab will be attached to the Celtic Explorer’s electricity and water and its sturdy design mean scientists — and their sensitive and valuable equipment — are protected while working during inclement weather. The mobile lab allows research equipment to be more easily and efficiently transported to sea. Previously, the equipment would be dismantled, shipped in crates and then re-installed, increasing costs, set-up time and risk of equipment damage. This mobile laboratory creates new possibilities to use non-specialized vessels such as offshore supply vessels, for sophisticated chemical, biological and geological research at sea.

The Northwest Atlantic Ocean removes vast amounts of carbon dioxide (CO2) from the atmosphere. While this “carbon sink” mitigates climate change, the CO2 offset must be measured to assess whether global efforts to reduce greenhouse gas emissions are effective. During the Celtic Explorer cruise, researchers will compare three different CO2 measurement systems including a high-accuracy sensor developed by Pro-Oceanus Systems Ltd. If the test on Celtic Explorer is successful, this made in Nova Scotia sensor can be installed on research and commercial vessels worldwide, increasing the data coverage from which to measure the ocean’s carbon sink.

During the Celtic Explorer expedition, the vessel will stop every 30 nautical miles and sample water from at least 24 different depths. At each depth, samples for a dozen different measurements will be collected, resulting in thousands of individual water samples that must be recorded and tracked. A unique, sample-tracking system initially developed at Fisheries and Oceans Canada’s Bedford Institute of Oceanography, enables data collection to occur efficiently while the labelling — known as “Bedford Stickers” — creates a cohesive collection process. The “Bedford Stickers,” which use adhesive that withstand wet and dry conditions and variable temperatures, are distributed by Cabot Shipping Supplies of Dartmouth, NS.

“OFI is an international hub for ocean science, bringing together researchers from both sides of the Atlantic to create safe, sustainable solutions for ocean development,” said Doug Wallace, Canada Excellence Research Chair in Ocean Science and Technology and an OFI researcher. “This research voyage illustrates the benefits of OFI, using made-in-Atlantic-Canada ingenuity to help assess climate change.”

The research vessel which departed Galway, Ireland on April 18, is scheduled to arrive in St. John’s, NL on April 26. The ship departs St. John’s April 27, returning to Galway on May 23. The scientific studies being conducted will help evaluate the impact of climate change on the ocean and identify how nutrients and oxygen move within the sea’s currents. Data collected will also allow detection of the ongoing acidification of deep ocean waters, including those which impact the ocean’s ecosystem.

About OFI

The Ocean Frontier Institute (OFI) is a collaborative research initiative to harness the vast potential of the world’s ocean and meet the ecological, economic and societal challenges of the future. OFI is a partnership between Dalhousie University, Memorial University of Newfoundland and the University of Prince Edward Island. Other partners include scientists from three of the Government of Canada’s federal laboratories, the Royal Canadian Navy, National Film Board of Canada, Nova Scotia Community College, provincial governments of Nova Scotia and Newfoundland and Labrador and various private sector businesses and industry. International research institutes involved in OFI are: Alfred Wegener Institute (Germany), Christian-Albrechts-Universitat zu Kiel (Germany), GEOMAR Helmholtz Centre for Ocean Research (Germany), Institute of Marine Research (Norway), LabexMer (France), Lamont-Doherty Earth Observatory of Columbia University (New York), Marine Institute, Galway (Ireland) and the Woods Hole Oceanographic Institution (Massachusetts).

About GO-SHIP

GO-SHIP (Global Ocean Ship-based Hydrographic Investigations Program) provides international coordination aiming at sustained decadal reference hydrographic section repeats (39 world-wide), collecting data related to physical oceanography, the carbon cycle, marine biogeochemistry and ecosystems. GO-SHIP feeds into the Ocean Observations Panel for Climate (OOPC), and the International Ocean Carbon Coordination Project (IOCCP) as part of the Global Ocean Observing System (GOOS), Global Climate Observing System (GCOS), and the World Climate Research Program (WCRP). By coordinating approximately decadal observations for the inventories of heat, freshwater, carbon, oxygen, nutrients and transient tracers, covering the ocean basins from coast to coast and full depth (top to bottom), with water column and surface water measurements of the highest accuracy, GO-SHIP is contributing greatly to detection of physical and biogeochemical changes in our ocean.
