Objectif(s): Areas of the Arctic have large rivers that send freshwater, nutrients, and particles onto the continental shelf. The largest example in Canada is the Mackenzie River which empties into the Beaufort Sea shelf. This shelf is very shallow and the river may have a large influence on its productivity, especially in spring when melting snow and ice make the river flow high. If climate change affects snow and ice cover, the river flow and seasonality may also be impacted. The main aim of this project is to determine the change in flocculation, particle size, and organic composition in the shelf water column as the shelf waters evolve from winter to spring conditions, documenting aggregation, deposition, and resuspension in this highly coupled river-shallow shelf system.
