“…However, in the Arctic seas conditions for photosynthesis are different from the lower latitudes since they are constrained by the ice cover and the lighting regime ( Boetius et al, 2013 ; Flint et al, 2019 ). By generalised characteristics of photosynthesis, the shelf of the Siberian seas resembles the so called «mesophotic ecosystems».…”

The bathymetric distribution of species of Annelida, Crustacea and Echinodermata from the region including the Kara, Laptev and East Siberian seas and the adjacent region of the deep-sea Central Arctic was analysed. We focused on vertical species ranges revealing zones of crowding of upper and lower species range limits. Using published data and in part the material obtained during the expeditions of the P.P. Shirshov Institute of Oceanology, we evaluated species vertical distribution from 0 m to the maximum depth of the Central Arctic (~4,400 m). The entire depth range was divided into smaller intervals; number of upper and lower limits of species depth ranges was counted and plotted to visualize the range limits crowding. Several zones of crowding of vertical species range limits were found for all analysed macrotaxa. The most significant zones occurred at depths of 450–800 m and 1,800–2,000 m. The first depth zone corresponds to the boundary between the sublittoral and bathyal faunas. The last one marks the boundary between the bathyal and abyssal faunas. Depths of these boundaries differ from those reported from other Ocean regions; possible explanations of these differences are discussed.

“…The Siberian shelf is one of the widest in the world, up to 800 km ( Weber, 1989 ). In addition, it is characterized by a strong fresh water outflow ( Flint et al, 2019 ). As an example, the annual freshwater discharge from all major Arctic rivers is approximately 3,300 km 3 , equivalent to 10% of the global river-off.…”

The absorbance and fluorescence of chromophoric fraction of dissolved organic matter (CDOM) have proved to be optical markers to study estuarine and coastal mixing, dynamics of quantitative and qualitative changes in DOM, and also necessary as preconditions for remote sensing techniques. Optical properties and distribution of CDOM of the Kara and Laptev seas were investigated during the 72nd cruise of the R/V Akademik Mstislav Keldysh in August-September 2018. Autochthonous material was found to be most abundant. The predominance of terrestrial-derived humic substances was observed for the Ob and Yenisei river-influenced regions. The transport of allochthonous DOM to the Laptev Sea occurred through the Vilkitsky Strait mainly along the coast of the Taimyr Peninsula, and the content of humic-like CDOM decreases about twofold at 50 m depth.
