• Deep sea sedimentary analogs for the Vostok ice core 

      Mortyn, P. Graham; Charles, Christopher D.; Ninnemann, Ulysses Silas; Ludwig, Kristen; Hodell, David A. (Peer reviewed; Journal article, 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 (Peer reviewed; Journal article, 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 ...
