  1. 1. Milankovitch Cycles in Chalks, Danish North Sea, Detected by Use of Magnetic Susceptibility

    Författare :Morten G. Stage; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; magnetic susceptibility; Maastrichtian; Milankovitch cycles; North Sea; chalk;

    Sammanfattning : Subdivision of the Maastrichtian chalk from the Danish North Sea has proven to be difficult because of the homogenous composition and appearance. A high-resolution subdivision of the chalk yields new information and better understanding of the depositional environment along with the possibility of an advantageous correlation. LÄS MER

    Sammanfattning : Paper IPre-Quaternary paleoclimate studies in Australia mainly focus on terrestrial records from the southeastern part of the continent. IODP Expedition 356 drilled on the northwestern Australian shelf, yielding Miocene-Pleistocene paleoclimate records in an area where climate archives are scarce. LÄS MER

  4. 3. Studies of the Arctic Ocean sea ice cover and hydrothermal heat fluxes

    Författare :Christian Stranne; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Oceanography; Arctic climate sensisitvity;

    Sammanfattning : Since reliable ice extent estimates from satellite data became available in 1979 the Arctic sea ice cover has followed a declining long term trend. Over the last decade the decline has accelerated with record low sea ice extents recorded in 2002, 2005, 2007 and 2012. LÄS MER
