Giant aufeis fields are the indicators of water exchange processes in the permafrost zone. The study of aufeis dynamics is relevant to assessing the state of the cryosphere in a changing climate. The Anmangynda aufeis which forms upstream of the Kolyma River basin, was as large as 6.8 km ² in the last century and is considered representative of the...

A review of the isotopic composition of precipitation collected from October 2020 to January 2022 at four locations in the Magadan oblast at a distance of 300 km from the shore of the Sea of Okhotsk is presented. It is shown that the isotopic composition of precipitation on the coast (the city of Magadan) differs significantly from the inland one b...

The transfer of water and energy fluxes between the ground and the atmosphere is influenced by soil moisture (SM), which is an important factor in land surface dynamics. Accurate representation of SM over permafrost-affected regions remains challenging. Leveraging blended SM from microwave satellites, this study examines the potential for satellite...

The huge Anmangynda aufeis is located in the valley of the river of the same name in the Magadan region in North-East of Russia. This is the only in the world aufeis site with a 30-years period of ground-based observations (1962–1991). The materials of these observations were supplemented with data obtained from the analysis of Landsat and Sentinel...

The potential contribution of the aufeis flow to the formation of the water balance of rivers during various phases of hydrological regime was calculated. Duri...

With permafrost warming, the observed discharge of the Kolyma River in northeastern Siberia decreased between 1930s and 2000; however, the underlying mechanism is not well understood. To understand the hydrological changes in the Kolyma River, it is important to analyze the long-term hydrometeorological features, along with the changes in the activ...

The hydrological implications of discontinuous permafrost thaw in peatland-dominated basins are not well understood. While there is evidence suggesting that permafrost-thaw-driven land cover change increases annual runoff and the runoff ratio in the Taiga Plains of northwestern Canada, few studies have evaluated the impact on small to medium sized...

Recent decades have seen a change in the runoff characteristics of the Suntar River basin in the mountainous, permafrost, hard-to-reach region of Eastern Siberia.

The subject of this research is the historical data on the origin, geographical distribution, seasonal and long-term variability of giant aufeis ice sills in the Russian Far East. Ice sills are the ice fields, the thickness and area of which reach up to 10-12 m and several tens of sq. km respectively. They are formed in severe climatic conditions a...

Climate warming and anthropogenic impact causes transformation of geocryological conditions in the river basins of the North-East of Russia. Changes in the thickness of the active layer, configuration of taliks, types of landscapes and other factors lead to transformation of water exchange processes between surface and groundwater runoff.
