    • Deposition and recirculation of tritium in the North Pacific Ocean 

      Stark, Sheila; Jenkins, William J.; Doney, Scott C. (American Geophysical Union, 2004-06-04)
      Tritium data, primarily from the GEOSECS and WOCE cruises of the 1970s and 1990s, are used to estimate the time-evolving 3H inventory of the North Pacific basin. In the years between the two surveys, there have been changes ...
    • Impact of circulation on export production, dissolved organic matter, and dissolved oxygen in the ocean : results from Phase II of the Ocean Carbon-cycle Model Intercomparison Project (OCMIP-2) 

      Najjar, Raymond G.; Jin, X.; Louanchi, F.; Aumont, Olivier; Caldeira, Ken; Doney, Scott C.; Dutay, J.-C.; Follows, Michael J.; Gruber, Nicolas; Joos, Fortunat; Lindsay, Keith; Maier-Reimer, Ernst; Matear, Richard J.; Matsumoto, K.; Monfray, Patrick; Mouchet, Anne; Orr, James C.; Plattner, Gian-Kasper; Sarmiento, Jorge L.; Schlitzer, Reiner; Slater, Richard D.; Weirig, Marie-France; Yamanaka, Yasuhiro; Yool, Andrew (American Geophysical Union, 2007-08-08)
      Results are presented of export production, dissolved organic matter (DOM) and dissolved oxygen simulated by 12 global ocean models participating in the second phase of the Ocean Carbon-cycle Model Intercomparison Project. ...
    • Influences on the oceanic biogeochemical cycling of the hybrid-type metals : cobalt, iron, and manganese 

      Noble, Abigail E. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2012-02)
      Trace metal cycling is one of many processes that influence ocean ecosystem dynamics. Cobalt, iron, and manganese are redox active trace metal micronutrients with oceanic distributions that are influenced by both biological ...
    • Radium isotopes as tracers of coastal circulation pathways in the Mid-Atlantic Bight 

      Rasmussen, Linda L. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2003-06)
      Pathways of exchange between the shelf and slope in the Mid-Atlantic Bight were investigated using a combination of radiochemical tracer and hydrographic measurements. The motivation was to provide evidence of transport ...
    • A study of North Atlantic ventilation using transient tracers 

      Doney, Scott C. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1991-08)
      The oceanic distributions of tritium 3H), 3He, and the chlorofluorocarbons (CFCs) can be used to constrain the time-scales of the major ventilation pathways for an ocean basin such as the North Atlantic. I present a new ...
