Dissolved inorganic carbon (DIC), total alkalinity (TA), water temperature, salinity and dissolved oxygen collected from discrete samples and profile observations during the Canadian Beaufort Sea Marine Ecosystem Assessment (CBS-MEA) F/V Frosti expedition (EXPOCODE 18DN20180803) in the Arctic Ocean, Beaufort Sea from 2018-08-03 to 2018-09-08 (NCEI Accession 0238161)

This dataset includes discrete sample and profile data collected during the Canadian Beaufort Sea Marine Ecosystem Assessment (CBS-MEA) F/V Frosti expedition (EXPOCODE 18DN20180803) in the Arctic Ocean, Beaufort Sea from 2018-08-03 to 2018-09-08. These data include water temperature, salinity, dissolved oxygen, dissolved inorganic carbon (DIC) and total alkalinity. Starting in 2017, Fisheries and Oceans Canada (DFO) conducted a survey of marine fishes and their habitats on the Canadian Beaufort Shelf and slope in August and early September each year. Sampling was conducted from the F/V Frosti at 144 stations along nine multi-year transects; and 32 non-transect stations. Standardized sampling was conducted at pre-determined depth stations using a variety of sampling equipment including benthic fishing trawls; plankton nets; sediment cores; and CTD and water sample profiles. The ocean acidification program was implemented in DFO’s Central and Arctic Region (Freshwater Institute) in 2017, funded by the Aquatic Climate Change Adaption Services Program (ACCASP). This submission covers measurements conducted in the Canadian Beaufort Sea in 2018.
