We, the science party of Leg 189 of the Ocean Drilling Program, express our thanks to those who provided the invaluable help that made the drilling expedition to the Tasmanian Gateway an outstanding success. Leg 189 could not have succeeded without the site survey data and other support provided by the Australian Geological Survey Organisation. Surveys by the German research vessel Sonne and the IFREMER research vessel L’Atalante added critical site survey data. We especially thank those who helped write the various versions of the proposal, some of whom did not participate in the leg. We greatly appreciated the dedicated support of the captain, the crew, the drilling team, and the ODP technicians aboard the JOIDES Resolution. The sometimes heavy weather during our leg placed the drill crew and the ODP technical staff under considerable pressure. Finally, the hard work and competence of the ODP Publication Services staff have ensured the timely publication of this volume.
