Abstract:

The primary objective of this research was to determine whether sediment is transported by sea ice from the various Russian rivers and arctic shelf areas to the western Arctic Ocean and, in particular, the Beaufort Sea. Knowledge of the precise sources of sediment entrainment by sea ice is important if the potential for contaminated sediment known to occur in parts of the Russian shelves to move into the Alaskan waters is to be assessed. Equally important is the quantification of the amounts of sediment in the Beaufort Sea pack ice and bottom sediment that was derived from various parts of the Russian Arctic.
