Coastal lakes of Southern Far East: climatic impact and natural hazards records

Abstract

The study of sediments of coastal lakes and palaeo-lakes in the southern Far East allowed us to identify several short-term paleoclimatic events in the transition “continent-ocean” zone. In the southern Kurils, palaeo-lakes that existed since the Late Glacial were found. Most of the lagoonal lakes were formed when sea level stabilized or declined slightly during the Holocene transgression. The most detailed data on hydroclimatic changes were obtained for the Middle-Late Holocene. The intensity of the summer monsoon and cyclogenesis activity associated with ocean and atmospheric anomalies in the Asia-Pacific region played a major role in the lake evolution. Sea water input to reservoirs occurred during extreme storms and tsunamis.
