    • Cadmium isotope variations in the Southern Ocean 

      Xue, Zichen; Rehkamper, Mark; Horner, Tristan J.; Abouchami, Wafa; Middag, Rob; van de Flierdt, Tina; de Baar, Hein J. W. (2013-09-09)
      Cadmium concentrations and isotope compositions were determined for 47 seawater samples from the high nutrient low chlorophyll (HNLC) zone of the Atlantic sector of the Southern Ocean. The samples include 13 surface ...
    • Evidence of silicic acid leakage to the tropical Atlantic via Antarctic Intermediate Water during Marine Isotope Stage 4 

      Griffiths, James D.; Barker, Stephen; Hendry, Katharine R.; Thornalley, David J. R.; van de Flierdt, Tina; Hall, Ian R.; Anderson, Robert F. (John Wiley & Sons, 2013-06-27)
      Antarctic Intermediate Water (AAIW) and Subantarctic Mode Water (SAMW) are the main conduits for the supply of dissolved silicon (silicic acid) from the deep Southern Ocean (SO) to the low-latitude surface ocean and therefore ...
    • Temporal stability of the neodymium isotope signature of the Holocene to glacial North Atlantic 

      van de Flierdt, Tina; Robinson, Laura F.; Adkins, Jess F.; Hemming, Sidney R.; Goldstein, Steven L. (American Geophysical Union, 2006-11-25)
      The neodymium isotopic composition of marine precipitates is increasingly recognized as a powerful tool for identifying changes in ocean circulation and mixing on million year to millennial time-scales. Unlike nutrient ...
