- Аннотация: Abstract—This work summarizes the archived data of geocryological and hydrogeological conditions in thewest of Nordenskiold Land on the Spitsbergen Archipelago. The historical data obtained in the Soviet periodduring coal exploration are reviewed together with the results of our own studies performed as part of the RussianScientific Arctic Expedition on Spitsbergen (RAE-S) in 2016–2020. With respect to geocryology, theregion is assigned to the zone of continuous permafrost. The thickness of rocks and sediments with temperaturesbelow zero is about 100 m near the coast and increases to 540 m on watersheds. The mean annual groundtemperature near the zero-amplitude depth varies from –3.6 to –2.2°C. Below this layer, the temperaturecurve in the top part of the section tends to deviate toward positive temperatures, reflecting the modern cycleof climate warming. From the hydrogeological point of view, the area belongs to the marginal zone of theWest Spitsbergen cryoadartesian basin. Seawater intrusions near the coast form saline subpermafrost aquifers,including those with temperatures below zero, reflecting the seawater (sodium chloride) compositionand hydraulic heads close to sea level. Fresh and slightly saline (sodium bicarbonate on the east coast ofGrønfjorden and magnesium–calcium sulfate in gypsum-bearing deposits on the west coast) subpermafrostwater with hydraulic heads reaching 100 m above sea level is fed by water-saturated ice in the deep layers oflarge glaciers.
