Oxygen isotopic analysis of marine carbonate shells (δ18Oc) is a standard paleoceanographic technique used to document the chronology of seawater temperature change. Shell δ18Oc depends not only upon seawater temperature, but also upon the isotopic composition of the seawater (δ18Ow; related to salinity) and any species-specific fractionation that occurs during biomineralization. In the past, the interpretation of shell δ18Oc has been based upon theoretical studies of chemical equilibrium and kinetics, or laboratory experiments involving the inorganic precipitation of CaCO3 from solution. Other methods have employed …

University of Maine Office of Research Administration: Grant Reports
This award, provided by the Antarctic Geology and Geophysics Program of the Office of Polar Programs, supports a marine geological investigation of the Amundsen Sea region toward a better understanding of the deglaciation history of the West Antarctic Ice Sheet (WAIS). The WAIS may be inherently unstable because it is the last marine-based ice sheet in the world. Unlike other embayments in West Antarctica, major ice streams draining into the Amundsen Sea from the interior of the WAIS lack buttressing ice shelves. Mass balance data for the distal portions of these ice streams (Pine Island and Thwaites glaciers) appear to …
