Sedimentary archives of long-term coastal evolution in the Siberian Arctic
Modern coastlines have over millennial time-scales developed by the interaction of geomorphological processes that continuously erode, deposit and remobilize sediment. Important parameters are the initial paleogeography, relative sea level and the local (wave) climate. Insight into the variability of these parameters can be obtained by investigating into the preserved deposits in the coastal zone. The aim of this project is to reconstruct the Holocene evolution of Buor Khaya Bay (71°N/130°E) by means of beach ridges, coastal lagoons and spit systems, and to quantify the role of key parameters such as relative sea level, extreme water levels and wave energy. The understanding of coastal change over longer timescales helps to interpret modern trends.
