Late Younger Dryas and early Holocene palaeoenvironments in the Skagerrak, eastern North Atlantic: A multiproxy study
A high-resolution study of palaeoenvironmental changes through the late Younger Dryas and early Holocene in the Skagerrak, the eastern North Atlantic, is based on multiproxy analyses of core MD99-2286 combined with palaeowater depth modelling for the area. The late Younger Dryas was characterized by...
