Centennial-scale vegetation dynamics and climate variability in SE Europe during Marine Isotope Stage 11 based on a pollen record from Lake Ohrid
To better understand climate variability during Marine Isotope Stage (MIS) 11, we here present a new, centennial-scale-resolution pollen record from Lake Ohrid (Balkan Peninsula) derived from sediment cores retrieved during an International Continental Scientific Drilling Program (ICDP) campaign.

Interestingly, the first forest contraction occurred during full interglacial conditions of MIS 11c; this event lasted for similar to 1.7 kyrs (406.2 -404.5 ka) and was characterized by substantial reductions in winter temperature and annual precipitation. Most notably, it occurred similar to 7 ka before the end of MIS 11c and similar to 15 ka before the first strong ice-rafted debris event in the North Atlantic.
