Oxygen and hydrogen isotope data were obtained in water samples collected in the Laptev Sea along the 130.5E meridian in route 63 of R/V "Akademik Mstislav Keldysh" in 2015 and 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 2015-2016 (for route 63) and in 2017 (for route 69). 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.
