    Abstract : Various sediment sampling and incubation techniques were used to characterize benthic biogeochemical processes important for an improved understanding of the oceanic carbon cycle. Recent flux data from the Arctic Siberian shelf are revealing differences (often by a factor of ten) between areas affected by the big Russian river outlets (high fluxes) and areas with low influence from land (low fluxes).

  4. 2. Influence of resuspension on sediment-water solute exchange and particle transport in marine environments

    Author : Elin Almroth Rosell; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; resuspension; benthic fluxes; oxygen; dissolved inorganic carbon; nutrients; dissolved iron and manganese; in situ chambers; benthic lander; organic matter transport; ecological modeling; Gothenburg Archipelago; Gulf of Finland; Baltic Sea; Loch Creran; Scotland;

    Abstract : Marine sediments contain a large pool of nutrients, which if released would contribute to increased eutrophication, in spite of decreased nutrient loads from land and atmosphere. Resuspension is a process, which might influence the release of nutrients from the sediment to the overlying water. READ MORE
