Vertical particle fluxes of sediment matter in the White Sea and western Arctic seas

Studies of vertical particle fluxes were carried out in 2006-2007 in the Dalnezelenetskaya Inlet of the Barents Sea and in the Chupa Inlet of the White Sea. Average annual particle flux volume in the Dalnezelenetskaya Inlet was 20-21 cm**3/m**2/day, or 1350-1400 mg/m**2/day, while in the Chupa Inlet it was 17-18 cm**3/m**2/day, or 500-550 mg/m**2/day. Sediment matter is mostly represented by flocculent detritus less than 100 µm in size. Currently estimated sedimentation rate is 0.9-1.1 mm/a in the Dalnezelenetskaya Inlet and 0.3-1.0 mm/a in the Chupa Inlet.
