Schwerpunktprogramm (SPP) 1158: Antarctic Research with Comparable Investigations in Arctic Sea Ice Areas; Bereich Infrastruktur - Antarktisforschung mit vergleichenden Untersuchungen in arktischen Eisgebieten, Geochemical signatures of tephra layers in Antarctic ice cores (EDML and Dome Fujii) Implications for source identification, palaeoatmospheric circulation and ice core correlations

Description: Tephra layers in isce cores from Antarctica help to constrain corrleations between distant deep ice cores and represent important time markers in the case they can be related to an eruption of known age. These time markers can be combined with existing chemo-stratigraphic parameters such as stratigraphy based on ä18O and äD/H. To that end, we plan to determine major and trace element compositions, grain size and morphologxy of tephra layers from the deep ice cores EPICA-Dronning Maud Land and Dome Fuji (Dronning Maud Land). This data will be used for correlations to other ice cores from Marie Byrd Land (West Antarctica), Vostok and Dome C (Wilkes Land). Such data will also allow the identification of potential source areas for the tephra, e.g.volcanic regions in Antarctica (Ross Sea Rift, Marie Bird Land, South Shetland Islands) as well as New Zealand, Patagonia and the volcanic ozean islands in the southern oceans.
