- Аннотация: In August 2017, comprehensive studies of ground ice were performed at central Yamal (Vaskiny Dachi research station). Research activities were undertaken on two sites with active thermodenudation processes and comprised the following: 1) sampling of ground ice (tabular ground ice, ice wedge ice) and enclosing ice deposits from exposures for various analyses (stable water isotope δD and δ18O, gaseous inclusions using headspace sampling method, gravimetric water content, major ions, radiocarbon dating, water extraction chemistry); 2) water sampling from the adjacent lake in order to understand the impact of thermocirque on the geochemistry of the lake water, 3) UAV overflights and tacheometric survey of thermocirques in order to assess the rate of edge retreat. https://hal.archives-ouvertes.fr/hal-01816115/
