Atlantic Ocean thermohaline circulation changes on orbital to suborbital timescales during the mid-Pleistocene
Kleiven, Helga (Kikki) Flesche; Jansen, Eystein; Curry, W. B.; Hodell, David A.; Venz, K. A. (Peer reviewed; Journal article, 2003-02-19)Mid-Pleistocene benthic ∂18O and ∂13C time series from the North Atlantic site 983 and Ceara Rise site 928 are compared to an array of existing isotopic records spanning the Atlantic basin and the geographic extremes of ... -
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 ...
