Acknowledgments
Our investigations were financially supported by the German Federal Ministry of Education,
Science, Research and Technology (BMBF). We thank Bettina Beeskow (AWl Potsdam) who
prepared most of the samples for radiocarbon dating. We also thank Dr. Mackensen and Prof.
K. Friedrichsen (stable isotope analyses), as well as Prof. P. M. Grootes (AMS dating) and the
staff of their laboratories for their efforts. A. Sher is thanked for the very constructive review.
This is contribution No. 1356 of the Alfred Wegener Institute for Polar and Marine Research,
