These data include dissolved inorganic carbon (DIC), total alkalinity (TA), partial pressure of CO2 (pCO2), methane, dissolved oxygen, water temperature, salinity and other measurements. As a part of the ArcticNet program; the "HiBio" project investigated the distribution of benthic organisms; particularly cold water corals and sponges. State of the ocean acidification was studied to understand the environment for these habitats in Davis Strait and Baffin Bay region.

This dataset includes discrete sample and profile data collected during the Canadian Beaufort Sea Marine Ecosystem Assessment (CBS-MEA) F/V Frosti cruise 18DN190802 (EXPOCODE 18DN20190802) in the Arctic Ocean, Beaufort Sea from 2019-08-02 to 2019-09-09. 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 2019.

This dataset includes discrete profile measurements of Dissolved inorganic carbon (DIC), total alkalinity, water temperature, salinity, dissolved oxygen, nutrients and other hydrographic and chemical data collected from discrete samples and profile observations during the CCGS Louis S. St-Laurent Joint Ocean Ice Study (JOIS-10) cruise (EXPOCODE 18SN20100915) in the Arctic Ocean from 2010-09-15 to 2010-10-15. The Joint Ocean Ice Study (JOIS) in 2010 involved the collaboration of Fisheries and Oceans Canada researchers with colleagues primarily from the U.S.A and Japan. This program forms an important Canadian contribution to international climate research programs and is comprised of two ongoing programs: the Beaufort Gyre Exploration Project (BGEP), a collaboration with Woods Hole Oceanographic Institution scientists and the Pan-Arctic Climate Investigation (PACI), a collaboration with Japan Agency for Marine-Earth Science and Technology (JAMSTEC) scientists. In 2010 JOIS also included ancillary programs carried out by researchers from: the International Arctic Research Center (IARC) in Fairbanks Alaska; Tokyo University of Marine Science and Technology (TUMSAT), Japan; Kitami Institute of Technology (KIT), Japan.

This dataset includes discrete profile measurements of dissolved inorganic carbon (DIC), total alkalinity, pH on total scale, water temperature, salinity, dissolved oxygen, nutrients and other hydrographic and chemical data collected from discrete samples and profile observations during the CCGS Louis S.
