We thank the organizers and crew of the Ocean Drilling Program for invitation to Leg 177 and for the receipt of data and samples. The present data set is based on samples provided by the Ocean Drilling Program (ODP). ODP is sponsored by the U.S. National Science Foundation and participating countries under the management of Joint Oceanographic Institutions. The Deutsche Forschungsgemeinschaft has funded sample processing through grant Ku-623/6 and Di-655/2. For sample preparation we are indebted to the Alfred-Wegener-Institut (AWI) team of technicians and student trainees. We acknowledge the review and constructive recommendations of Steven A. Hovan.
