Astronomical forcing of mediterranean climate during the last 5.3 million years

Abstract

The prime target of this investigation was to provide a better understanding of the processes underlying the onset of major south- and northern hemisphere glaciations around 2.8 Ma BP. Two issues had to be considered before we started our investigation. Firstly, are there sufficiently long and uninterrupted (marine) sequences available and, secondly, what climatic proxies are suitable for paleoclimatic reconstructions.
