Title: {Carbon and oxygen isotope signals from marine ostracod calcite - results from present and past oceans}
Abstract: Systematic stable isotope studies on ostracod calcite are generally rare, in particular for marine taxa only the work of DIDIE & BAUCH (2002) provides first clues towards an improved understanding of ostracod stable isotope data in paleoceanography. Here we present analyses from recent near surface sediments from the Gulf of Taranto, the Levantine Basin (15 ka, both Mediterranean Sea) and the Paleocene of Tunisia (southern Tethyan margin). Data are compared to those from selected benthic foraminiferal taxa from which the living habitat and the isotopic disequilibria from ambient sea-water are well known. In addition, size fractions of monospecific samples have been studied in order to test whether a size/mass dependent change exists with respect to the isotopic composition of the carapace calcite.
