Project description

This project uses the spatial distribution and geochemistry of the planktonic chitinozoans and graptolites to reconstruct and evaluate the climatic impact of the deflection of water masses during the onset of the end-Ordovician glaciation. It provides a test for the "closure of ocean gateway hypothesis", which is a recently postulated cause of Late Pliocene-Pleistocene glaciation.
