A huge biocatalytic filter in the centre of Barents Sea shelf?
A primary production model for the Barents Sea shows a hot spot of organic carbon settlement to the sea bed over100 km long, a shallow pile of highly permeable sediments (mainly large Balanus , Mya and Pecten shell fragments over1 cm in size) of glacial origin. Hydrodynamic flow models suggest an in...
