Sedimentary deposits from terrestrial environments (lakes, moraines, dunes, loess, and permafrost) and the polar oceans represent unique palaeoclimate archives used for the reconstruction of the late Pleistocene to Holocene environmental history of the periglacial and offshore realm. The inference of palaeoenvironmental scenarios is based on sedimentological, geochemical, and micropaleontological data (diatoms, chironomids, ostracods, pollen). The above picture gives an impression of a field campaign to Lake Bolshoi Toko in the Stanovoy Mountains (Yakutia) that took place in spring 2013. The ice-based tripod, equipped with a piston corer, was used for the recovery of up to 6 metre long lacustrine sediment cores from the lake bottom. Other study areas are:
