CACHE-DRAM: DRivers and AMplifiers of late Quaternary climate change

Based on these new datasets, the phasing between different regions during the transition from the last glacial period into the Holocene will be investigated and used to test hypotheses about the mechanisms involved. In collaboration with the University of Bristol (Prof. P. Valdes), the datasets will be used to validate palaeoclimate model output.

The 10Be record from the Berkner Island core will allow a detailed reconstruction of the solar forcing over the past 10 000 years and offer the opportunity to estimate the impact of solar variation on climate variability of the Holocene. The connection between the dust, sea ice, temperature and CO2 records that are derived from ice cores will be used as input for carbon cycle modelling, contributing to a more detailed understanding of the feedback mechanisms governing past changes in CO2.
