Recent changes in sediment accumulation rates in Adventfjorden, Svalbard

Recent sediment accumulation rates in Adventfjorden (Svalbard), a small subpolar fjord, were determined by 210 Pb and 137 Cs dating. Modern rates in the central basin decrease downfjord from 1.87 to 0.87 cm y −1 (2.6 to 1.19 g cm −2 y −1 ). Comparison of the modern values (1986–2001) with older ones (1963–86) reveals a marked increase in sediment accumulation rates in the last ten years. This correlates well with recent climate changes (warming and increase in precipitation).
