Last interglacial (MIS 5e) surface circulation in the North Atlantic and Nordic seas, based on dinoflagellate cysts
Sediments from the last interglacial (MIS 5e) were studied for their dinoflagellate cyst (dinocyst) content from cores across the North Atlantic and Nordic seas, in order to trace changes in the interaction between the warm water masses of the northward flowing Gulf Stream/North Atlantic Drift curre...
