Vertical particle fluxes in the coastal areas of the Barents and White Seas

The studies of vertical particle fluxes were performed in 2006–2007 in Dalnezelenetskaya Inlet (the Barents Sea) and Chupa Inlet (the White Sea). The average annual particle flux in Dalnezelenetskaya Inlet was 20–21 cm³/(m² day), or 1350–1400 mg/(m² day), while, in Chupa Inlet, it was 17–18 cm³/(m² day), or 500–550 mg/(m² day). The sedimentary matter is mostly represented by flocculent detritus less than 100 μm in size. Currently, the estimated sedimentation rate constitutes 0.9–1.1 mm per annum in the DI and 0.3–1.0 mm per annum in the Chupa Inlet.
