The retreat of the multi-year sea ice over the last decades, and the changes in ice and ocean circulation are tightly linked to changes in the heat and fresh water distribution with consequences for the gas exchange between ocean and atmosphere, for biogeochemical cycling and for organisms and ecosystems in the sea ice, in the water column and on the sea floor. This dataset includes discrete bottle measurements of Dissolved Inorganic Carbon (DIC), Total Alkalinity, pH on total scale, water temperature and salinity, oxygen, nutrients, CFCs, Dissolved organic carbon and other parameters measured onboard the R/V Polarstern in the central Arctic Ocean during the PS-94, ARK-XXIX/3, TransArc-II cruise (EXPOCODE 06AQ20150817) from 2015-08-17 to 2015-10-15. fr: The expedition PS94 Trans-Arctic survey of the Arctic Ocean in transition ("TransArc II") aimed at capturing the physical, biological, and chemical changes of the Arctic Ocean.
