    • Dissolved inorganic carbon (DIC), total alkalinity (TA), pH, pCO2, methane, dissolved oxygen, nutrients, temperature, salinity, and other measurements collected from discrete samples and profile observations during the R/V Neil Armstrong Davis Strait Observing System (DSOS) cruise "AR69-04" (EXPOCODE 33VB20221001) in Davis Strait, Baffin Bay, northern Labrador Sea, North Pacific Ocean from 2022-10-01 to 2022-10-22 (NCEI Accession 0291292)

    Metadata Updated: November 1, 2025

    Oceanographic sampling of physical, chemical, and biological parameters was conducted along selected fixed sections in Davis Strait, Baffin Bay, northern Labrador Sea, North Atlantic Ocean at full water depths during the R/V Neil Armstrong Davis Strait Observing System (DSOS) cruise "AR69-04" (EXPOCODE 33VB20221001) from 2022-10-01 to 2022-10-22. The cruise is part of DSOS's long-term, high-frequency repeat program. CTD casts were performed at all stations, and discrete water samples were collected in Niskin bottles using the CTD/Rosette system. The cruise was designed to investigate Arctic-North Atlantic interactions, including the variability and trend of freshwater, heat, carbon, oxygen, and nutrient fluxes, as well as ecosystem responses to climate change. This effort was conducted in support of the NSF (OPP1902595) and Fisheries and Oceans, Canada (OFSI).
