    • 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 ...

    • Deep submarine infiltration of altered geothermal groundwater on the south Chilean Margin 

      Clementi, Vincent J.; Rosenthal, Yair; Bova, Samantha C.; Thomas, Elizabeth K.; Wright, James D.; Mortlock, Richard A.; Cowling, Owen C.; Godfrey, Linda V.; Childress, Laurel B.; Aiello, Ivano W.; Avila, Alejandro; Biggs, William; Charles, Christopher D.; Cheung, Anson H.; deLong, Kimberly; Dove, Isabel A.; Du, Xiaojing; Estes, Emily R.; Fuentes, Ursula; García-Lasanta, Cristina; Goldstein, Steven L.; Golub, Anna; Hagemann, Julia Rieke; Hatfield, Robert G.; Haynes, Laura L.; Hess, Anya V.; Irvali, Nil; Kiro, Yael; Monteagudo, Minda M.; Lambert, Jonathan E.; Li, Chen; Longo, William M.; McGrath, Sarah; Riechelson, Hailey; Robinson, Rebecca S.; Sarao, John; Sproson, Adam D.; Taylor, Shawn; Yokoyama, Yusuke; Yu, Siyao M. (Journal article; Peer reviewed, 2022)
      Submarine groundwater discharge is increasingly recognized as an important component of the oceanic geochemical budget, but knowledge of the distribution of this phenomenon is limited. To date, reports of meteoric inputs ...

    • 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 ...

    • The Sediment Green-Blue Color Ratio as a Proxy for Biogenic Silica Productivity Along the Chilean Margin 

      Li, Chen; Clementi, Vincent J.; Bova, Samantha C; Rosenthal, Yair; Childress, Laurel B.; Wright, James D.; Jian, Zhimin; Aiello, Ivano W.; Avila, Alejandro; Biggs, William; Charles, Christopher D.; Cheung, Anson H.; deLong, Kimberly; Dove, Isabel A.; Du, Xiaojing; Estes, Emily R.; Fuentes, Ursula; García-Lasanta, Cristina; Goldstein, Steven L.; Golub, Anna; Hagemann, Julia Rieke; Hatfield, Robert G; Haynes, Laura L.; Hess, Anya V.; Irvali, Nil; Kiro, Yael; Monteagudo, Minda M.; Lambert, Jonathan E.; Longo, William M.; McGrath, Sarah; Riechelson, Hailey; Robinson, Rebecca S.; Sarao, John; Sproson, Adam D.; Taylor, Shawn; Yokoyama, Yusuke; Yu, Siyao M. (Journal article; Peer reviewed, 2022)
      Sediment cores recently collected from the Chilean Margin during D/V JOIDES Resolution Expedition 379T (JR100) document variability in shipboard-generated records of the green/blue (G/B) ratio. These changes show a strong ...
