8.2 ka event and others cold climate oscillations in middle Holocene – evidence from Suchar Wielki Lake, NE Poland

Abstract

The best-known climate change in the middle part of the Holocene is an abrupt cooling around 8200 cal. yrs BP (e.g. O’Brien et al., 1995; Bond et al., 1997). This oscillation, known as the 8.2 ka event, was recognised in all most important past climate records, i.e. in the Greenland ice cores (GRIP and GRIP2) and in North Atlantic deep sea cores (O’Brien et al., 1995; Bond et al., 1997), and then it was demonstrated in many records in the world
