Shifts in North Atlantic surface water regimes during the last interglacial-glacial cycle (late Quaternary) investigated by coccolithophore-based ecological and chemical proxies
Coccolith-based palaeoenvironmental proxies were tested and applied for the reconstruction of environmental conditions and likely influences in the North Atlantic during the last c. 150 000 years (MIS 6-1), combining palaeoenvironmental tools such as coccolith assemblages, coccoliths carbonate contr...
