Abstract

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
rates of well-dated marine sediment cores and data onsediment export to
the central Arctic Ocean byseaice and through bottom currents.
Within the uncertainties of the calculations, input and output arevery weil balanced.
The calculation reveals that the sediment budget of the Laptev Sea is
mainly controlled byfluvial and coastal sediment input. The major fraction of
the material is simply deposited on the Laptev Sea shelf. However, for the
western Laptev Sea, where sedimentation rates are low due to the absence of
large rivers, export byseaice is the main output factor.
