Characteristics of wave-built sedimentary archives in Buor Khaya Bay (71°N/130°E), Siberian Arctic, Russia.
Prograded sequences of beach deposits preserve valuable paleoenvironmental information on the long-term variability of sea level, climate forcing and sediment supply driving centennial to millennial coastal evolution. Buor Khaya Bay, NE Siberian Arctic, is located at the transition between the Verkhoyansk mountain range and the southern Laptev Sea and is one of the few places along the Russian arctic coast, where wide beach-ridge systems exist. The area was visited during an expedition in August 2017 in order to obtain baseline information on the potential of five different coastal sedimentary systems (barriers, spits, lagoons, beach-ridge systems), for the reconstruction of Holocene sea level and past sea-ice extent. The project is at an early stage of investigation and we present first insights into a new and promising area of investigation. Work will be continued in summer 2018.
