Oxygen, hydrogen, and carbon isotope data with the [DIC] concentrations were analyzed in water samples collected in the East Siberian Sea along the Kolyma and Indigirka sub-meridian profile in route 69 of R/V "Akademik Mstislav Keldysh" in 2017. Sampling was done using the Rosette SBE 32. Isotope analysis was performed in the laboratory of Isotope Geochemistry and Geochronology of IGEM RAS (Moscow) in 2017. Oxygen isotope composition of water samples determined by CF IRMS using the Delta V+ with the GasbenchII option (Thermo, Germany). Hydrogen isotope composition of water samples determined by DI IRMS using the DeltaPlus with H/Device option (Thermo, Germany). The δD and δ¹⁸O values were determined with an accuracy of 0.3 and 0.05 per mill correspondently. The δ¹³C(DIC) and DIC concentrations were analyzed using the Delta V+ with the GasbenchII option (Thermo, Germany). The δ¹³C(DIC) and [DIC] values were determined with an accuracy of 0.05 per mill and 5 rel. % correspondently.
