Characterizing the Eemian-Weichselian transition in northwestern Europe with three multiproxy speleothem archives from the Belgian Han-sur-Lesse and Remouchamps cave systems
peer reviewed Interglacial to glacial transitions represent the most drastic turnovers in the Quaternary climate system. Yet, millennial-scaled climate variability and stochastic internal variability that result in these transitions remain still poorly understood. Here, three speleothem archives fro...

peer reviewed Interglacial to glacial transitions represent the most drastic turnovers in the Quaternary climate system. Yet, millennial-scaled climate variability and stochastic internal variability that result in these transitions remain still poorly understood. Here, three speleothem archives from two different cave systems in Belgium (Han-sur-Lesse and Remouchamps) are investigated using a multiproxy approach in order to characterize the last interglacial to glacial transition. The studied samples roughly span the period between 125 ka and 100 ka, covering a large part of the Eemian and early Weichselian.
