An estimation of the sediment budget in the Laptev Sea during the last 5,000 years
This article presents a mass balance calculation of the sediment sources and sinks ofthc Laptev Sea. Sediment input into three regional sectors calculated on the basis offluvial sediment discharge and coastal erosion sediment supply is compared with sediment output as estimated from sedimentation ra...
