Marine CO2 system and inorganic nutrients in the water column along the Fugløya-Bjørnøya section in the Barents Sea in 2020
Marine CO2 system data (total alkalinity, and total dissolved inorganic carbon) and nutrients were collected from full water column on the IMR repeat section between Fugløya-Bjørnøya in the Barents Sea Opening onboard the RV Johan Hjort on cruise number 2020202. The seawater samples were collected i...
