Vertical particle flux on the shelf off northern Spitsbergen, Norway
Suspended and sedimented particulate matter was examined alongtransects on the continental shelf off northern Spitsbergen, Norway, during summer1991. The transects were situated in non-ice-covered areas dominated by Atlanticwater, areas with multi-year ice and the marginal ice zone. The variability...
