The objectives of Expedition 325 are to establish the course of sea level change, to define sea-surface temperature variations, and to analyze the impact of these environmental changes on reef growth and geometry for the region over the period of 20-10 ka. To meet these objectives, a succession of fossil reef structures preserved on the shelf edge seaward of the modern barrier reef were cored from a dynamically positioned vessel in February-April 2010. A total of 34 boreholes across 17 sites were cored in depths ranging from 42.27 to 167.14 meters below sea level (lowest astronomical tide [LAT] taken from corrected EM300 multibeam bathymetry data). Borehole logging operations in four boreholes provided continuous geophysical information about the drilled strata. The cores were described during the Onshore Science Party (OSP) at the IODP Bremen Core Repository (Germany) in July 2010, where minimum and some standard measurements were made. Preliminary shipboard dating of core catcher samples and initial observations of the cores made during the OSP confirm that coral reef material ranging in age from >30 to 9 ka was recovered during Expedition 325. Further postcruise research on samples taken during the OSP is expected to fulfill the objectives of the expedition.completedQuaternary geologyAnthozoaAustralasiaAustraliabiostratigraphybody wavesboreholesboundstonecarbonate rocksCenozoicchronostratigraphyCnidariacontinental shelfCoral Seacoresdeglaciationdensitydrillingelastic waveselectrical conductivityExpedition 325Great Barrier ReefHoloceneIntegrated Ocean Drilling ProgramInvertebratalimestonelithostratigraphymagnetic propertiesmagnetic susceptibilitymarine drillingmarine sedimentsmicrobialiteP-wavesPacific Oceanpaleoclimatologypaleomagnetismphysical propertiesPleistoceneporosityQuaternaryQueensland Australiareefsresistivitysea-level changessedimentary rockssedimentsseismic wavesSouth PacificSouthwest Pacificupper Pleistocenevelocitywell logsWest PacificEnglishgeoscientificInformation145.0000151.0000-20.0000-15.0000Supplemental information/data is available in the online version of this article
