摘要：

As a first step to explore the effects of water, sediment, chemical and heat fluxes of the Yukon River on the ecosystem and sea ice formation in the Bering Sea, discharge, water turbidity and water temperature were monitored at a downstream site in June 2006-September 2007. The monitoring revealed that suspended sediment concentration fluctuates in the ice-covered season by rainfall sediment runoff in the upstream in late fall and probably by the movement of covered ice mass in early spring. During the high river sediment load in summer, the sediment plume was formed around the Yukon river delta. In order to clarify the dynamic behaviors of river water, the sediment plume was simulated by using a CFD program with a three-dimensional topographic model. The simulations were agreeable to observations off the Yukon delta and to the dispersal pattern of sediment plume by a MODIS image.
