  • Deep sea sedimentary analogs for the Vostok ice core 

    Mortyn, P. Graham; Charles, Christopher D.; Ninnemann, Ulysses Silas; Ludwig, Kristen; Hodell, David A. (American Geophysical Union and the Geochemical Society, 2003-08-07)
    Many applications of the Vostok ice core depend critically on the ability to make stratigraphic ties to marine records in the adjacent Southern Ocean. Here we present oxygen isotopic records from high accumulation rate ...
  • Pleistocene vertical carbon isotope and carbonate gradients in the South Atlantic sector of the Southern Ocean 

    Hodell, David A.; Venz, K. A.; Charles, Christopher D.; Ninnemann, Ulysses Silas (American Geophysical Union and the Geochemical Society, 2003-01-10)
    We demonstrate that the carbon isotopic signal of mid-depth waters evolved differently from deep waters in the South Atlantic sector of the Southern Ocean during the Pleistocene. Deep sites (>3700 m) exhibit large ...
