Abstract
Particulate matter of lithogenic and biogenic origin is often highly enriched in Arctic sea ice. Entrainment of particles is most effective during fall freeze-up over shallow Arctic shelves.
Particle entrainment into newly forming sea ice was investigated during the Transdrift III expedition in October 1995, conducted in the Laptev Sea, Siberian Arctic. Considering the prevailing calm meteorological conditions, processes related to propagating wave fields are identified as possible mechanisms for particle entrainment into the forming sea ice, where particles were significantly enriched as compared to the underlying water column.
Due to high drift velocities and a loose ice cover during the observed freeze-up, sediment export by sea ice from near-shore areas towards the deep basins of the Arctic Ocean was likely.
