Macrobenthos of Yenisei Bay and the adjacent Kara Sea shelf

  title={Macrobenthos of Yenisei Bay and the adjacent Kara Sea shelf},
  author={Sergey Galkin and Andrey Vedenin},
Trawl samples were collected in the northern region of Yenisei Bay and adjacent parts of the Kara Sea shelf. A total of eight stations were taken. We found more than 200 species of benthic organisms. A consecutive replacement of benthic communities is observed when going to the north from the Ob and Yenisei estuaries to the open parts of the sea. We could distinguish four different species complexes in the investigated area: a brackish-water complex where Saduria entomon is dominant; an… 
Meiobenthos and nematode community in Yenisei Bay and adjacent parts of the Kara Sea shelf
The trophic structure of the taxocene of nematodes in Yenisei Bay is dominated by nematode with well-defined stoma and are differently armed, and the estuary and shelf are dominated by selective and nonselective deposit feeders.
Benthic fauna of Tsivolki Bay (Novaya Zemlya Archipelago, Kara Sea)
Benthic fauna in Tsivolki Bay (Novaya Zemlya Archipelago, Kara Sea) has been studied during the voyage of the R/V Professor Shtokman in 2013 and 2014. A peculiar feature of the bay is the presence of
Vertical zonation of the Siberian Arctic benthos: bathymetric boundaries from coastal shoals to deep-sea Central Arctic
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, revealing zones of crowding of upper and lower species range limits.
Fauna associated with shallow-water methane seeps in the Laptev Sea
The development of the described communities at the shallow-water methane seep macrofauna can be related to pronounced oligotrophic environment on the northern Siberian shelf.
The history of study, the taxonomic composition and the origin of the sea anemone fauna of the Kara Sea (Actiniaria, Anthozoa, Cnidaria)
Based on the study of new collection material and literature data, the composition of the sea anemone fauna of the Kara Sea is described. It includes 13 species of 7 families. Among them are 10
Unraveling the effects of environmental drivers and spatial structure on benthic species distribution patterns in Eurasian-Arctic seas (Barents, Kara and Laptev Seas)
The results suggest that different environmental factors determine the variation of Eurasian-Arctic benthic community composition within the spatial scales considered and highlight the importance of considering the diverse spatial structure of species communities in marine ecosystems.
Uniform bathymetric zonation of marine benthos on a Pan-Arctic scale


Macrobenthos of the Ob River estuarine zone and of the adjacent regions of the Kara Sea
The composition and distribution of the macrobenthic communities in the Ob estuary and the adjacent Kara Sea shelf were studied during the 54th cruise of the R/V Akademik Mstislav Keldysh. With the
Current state of zoobenthos in two estuarine bays of the Barents and Kara Seas
Benthic studies in two seasonally ice-covered Arctic estuaries include description of the faunal composition, biodiversity, quantitative distribution, and biogeographic structure of theFauna and Species diversity increases from the inner parts to the open sea, while the homogeneity of the community reflects the opposite tendency.
The Kara Sea ecosystem: phytoplankton, zooplankton and benthos communities influenced by river run-off
Phytoplankton, zooplankton and macrozoobenthos in the estuaries of Ob and Yenisei and the adjacent southern Kara Sea were investigated during three expeditions with RV "Akademik Boris Petrov" in
Brittle star fauna (Echinodermata: Ophiuroidea) of the arctic northwestern Barents sea: composition, abundance, biomass and spatial distribution
It is found that brittle stars dominate epibenthic communities on Arctic shelves and locally reach very high abundances, and dense beds of Ophiocten sericeum seem to be a general phenomenon on high-Arctic shallow shelf banks.

Manganese nodules and other ferromanganese oxide deposits from the Atlantic Ocean
Atlantic manganese nodules and encrustations are most abundant in areas of slow sedimentation beneath the carbonate compensation depth or where currents inhibit sediment accumulation. They
