We gratefully acknowledge the hard work and persistence of our shipboard and shore-based scientific colleagues who produced the body of publications describing Leg 202's scientific results that are synthesized here. We are also most grateful to the Leg 202 ship's crew and the marine technicians as well as to our Staff Scientist Peter Blum, who endured stormy seas and extremely trying drilling conditions to accomplish a successful leg. This manuscript has benefited from thoughtful and constructive reviews by Bill Ruddiman, Christina Ravelo, and Chris Poulsen. We also thank Frank Lamy, Heather Benway, Silke Steph, Arne Sturm, and Aysel Sorensen for critical comments, preparation of figures, and editorial help. This research used samples and/or data provided by the Ocean Drilling Program (ODP). ODP is sponsored by the U.S. National Science Foundation (NSF) and participating countries under management of Joint Oceanographic Institutions (JOI, Inc.). Preparation of this synthesis chapter was supported by JOI U.S Science Support Panel (USSSP) and NSF Grants 0319016 and 0426410 (Alan Mix) and through funding from the Deutsche Forschungsgemeinschaft, DFG Grants Ti 240/12 and 13 (Ralf Tiedemann).
