Results of the Barents Sea waters isotopic studies. R/V "Dalnie Zelentsy" March-April 2021

To determine the values of isotopic parameters δ18O and δ2H, samples were collected in March and April 2021 on the Dalnie Zelentsy research vessel (property of the Murmansk Marine Biological Institute of the Russian Academy of Sciences). A total of 107 samples was collected and analyzed at 27 stations . Also, 6 pairs of ice and subglacial water samples were collected to estimate the fractionation of the stable isotopes during ice formation in a real setting.
