“…Drilling penetrated two major lithologic units; an upper unit (Unit I) consisting of a deglacial package which is underlain by a lower unit (Unit II), identifiable by visible diagenetic properties of the sediments caused by subaerial exposure and meteoric diagenesis during sea-level lowstand (Camoin et al, 2007b;Thomas et al, 2009;Fujita et al, 2010). All cores investigated herein intersected the contact between Unit I and Unit II, but only detailed logging of Unit I was carried out for this study.…”

“…(Oppo et al, 2001;Cheng et al, 2006;Thomas et al, 2009). In this sense, the early sea level rise and the cold snap, defined by the AC transition at 130,000 years ago (Esat et al, 1999;Beets and Beets, 2003;Gallup et al, 2002;Siddall et al, 2008;Thomas et al, 2009;Fujita et al, 2010) could be due to changes in ocean circulation precipitated by iceberg discharges. The subsequent rapid warming and rapid sea level rise also fit in as part of a Heinrich-type sequence.…”

The timing and courses of deglaciations are key components in understanding the global climate system. Cyclic changes in global climate have occurred, with growth and decay of high latitude ice sheets, for the last two million years. It is believed that these fluctuations are mainly controlled by periodic changes to incoming solar radiation due to the changes in Earth's orbit around the sun. However, not all climate variations can be explained by this process, and there is the growing awareness of the important role of internal climate feedback mechanisms. Understanding the nature of these feedbacks with regard to the timing of abrupt global sea-level and climate changes is of prime importance. The tropical ocean is one of the major components of the feedback system, and hence reconstructions of temporal variations in sea-surface conditions will greatly improve our understanding of the climate system. The Integrated Ocean Drilling Program (IODP) Expedition 325 drilled 34 holes across 17 sites in the Great Barrier Reef, Australia to recover fossil coral reef deposits. The main aim of the expedition was to understand the environmental changes that occurred during the last ice age and subsequent deglaciation, and more specifically (1) establish the course of sea-level change, (2) reconstruct the oceanographic conditions, and (3) determine the response of the reef to these changes. We recovered coral reef deposits from water depths down to 126 m that ranged in age from 9,000 years to older than 30,000 years ago. Given that the interval of the dated materials covers several paleoclimatologically important events, including the Last Glacial Maximum, we expect that ongoing scientific analyses will fulfill the objectives of the expedition.
