Abstract. Variability of surface water masses the Laptev and East Siberian seas in August–September 2018 is studied using situ satellite data. In data were collected during ARKTIKA-2018 expedition then complemented with satellite-derived sea temperature (SST), salinity (SSS), height, wind speed, ice concentration. The estimation SSS fields challenging high-latitude regions, precision soil moisture ocean (SMOS) retrieval improved by applying a threshold on weekly error. For first time this...
Arctic summer and winter sea-ice extent is continuously declining as a result of climate change, affecting the hydrography biogeochemical cycles on seasonally ice-free Eurasian Shelves. The prolongation open-water season causes higher sediment resuspension coastal erosion due to larger wind fetch wave heights. This impacts optical properties water column hence biological productivity in this region. During “Transarktika-2019” leg 1 late 2019, comprehensive dataset data was collected...

We discuss the experience of conducting special oceanographic observations in ice camp experimental drifting station. In a changing climate Barents Sea is exposed to an important change heat and salt balance system ocean currents. These changes are related distribution Atlantic waters, surface waters sea ice, so station appears be best-adapted platform for complex simultaneous measurements water properties phenomena. The was organized as “vessel — ice” during first leg “Transarktika-2019”...
<p>The last 10 years of Arctic Ocean observations showed the dramatic changes and new records sea ice minimum. The largest variations were observed in Eastern Arctic: Kara, Laptev, East-Siberian seas. This region is a key area important freshwater input from great Siberian rivers (Ob’, Yenisei, Lena). remote remains one less studied Ocean, although several regular expeditions (such as NABOS or Transdrift) together with special following Northern Route, such...
