Ion concentration, salinity and total dissolved solids (TDS) in Holocene multistage massive ice near the Sabettayakha River mouth, Yamal Peninsula, northwest Siberia

Holocene massive ground ice near the Sabettayakha River mouth, on the coast of the Gulf of Ob, Yamal Peninsula, northwest Siberia is studied. Three boreholes (Nr 12, 17 and 42) were drilled within the Holocene lagoon-marine floodplain of the Ob Bay and the first lagoon-marine terrace near the Sabettayakha River mouth in winter 2014 using a light portable drill. The drilling retrieved a 12 cm diameter core in an almost undisturbed condition. Massive ice was sampled from these boreholes for isotope, chemical and palynologic analyses. The ion concentration (%-equivalent - %-eq), salinity (S) and total dissolved solids (TDS) concentration was determined in newly melted snow, lake ice, sea ice and sea water. A single series of geochemical analysis of massive ice with other cryospheric objects was carried out for more reliable comparison and correct interpretation of geochemical data
