This has been clearly demonstrated by the recent break up of the Larsen A Ice Shelf. Drilling at Ocean Drilling Program Site 1098, Palmer Deep, western Antarctic Peninsula, recovered almost 50 m of sediments that record the paleoceanographic and paleoclimatic history of the region from the last glacial maximum through the rapid climate oscillations of deglaciation into the Holocene. This sedimentary section will provide a wealth of high-resolution paleoenvironmental data from Antarctica that will be useful for climate modelers and paleoceanographers alike. This data report presents the preliminary results of a high-resolution, microscale sediment fabric study of the postglacial sediments from Palmer Deep Site 1098. These sediments have previously been described as being annually laminated; however, this investigation shows that although the interpretation of this sequence as seasonal sediments is most likely correct, there are a number of features that indicate there is strong interannual variability affecting the laminations.completedQuaternary geologyalgaeAntarctic OceanAntarctic PeninsulaAntarcticaCenozoicclimate changecoresdeglaciationdiatomsfabricglacial geologyglaciationHoloceneLeg 178marine sedimentsmicrofossilsNeoglacialOcean Drilling Programocean floorsODP Site 1098paleo-oceanographypaleoclimatologyPalmer DeepPlantaepostglacial environmentQuaternaryreconstructionsedimentsthin sectionsultrastructureurn:org.iodp:exp:178urnlargerWorkCitationcampaignurn:org.iodp:exp:178:site:1098urnlargerWorkCitationstudyurn:org.iodp:exp:178urnlargerWorkCitationcampaignEnglishgeoscientificInformation-64.1228-64.1228-64.5143-64.5143Data report; available only on CD-ROM in PDF format and on the Web in PDF or HTML; access date Feb. 24, 2002application/pdfunknownSEDIS Publication Catalogueana.macario@awi.dehttp://sedis.iodp.org/pub-catalogue/informationpointOfContacthttp://www-odp.tamu.edu/publications/178_SR/VOLUME/CHAPTERS/SR178_18.PDFdownload
