      Iron is a redox active trace metal micronutrient essential for primary production and nitrogen acquisition in the open ocean. Dissolved iron (dFe) has extremely low concentrations in marine waters that can drive phytoplankton ...
    • The marine biogeochemistry of molybdenum 

      Tuit, Caroline Beth (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2003-02)
      Prevailing wisdom holds that the vertical distribution of molybdenum (Mo) in the open ocean is conservative, despite Mo's important biological role and association with Mn oxides and anoxic sediments. Mo is used in both ...

      On August 3 - 4, 1989, the Marine Policy Center of Woods Hole Oceanographic Institution hosted the initial meeting of the Marine Biological Diversity Working Group. The formation of this working group was fostered as part ...
    • Marine biotoxins and harmful algae : a national plan 

      Anderson, Donald M.; Galloway, Sylvia B.; Joseph, Jeanne D. (Woods Hole Oceanographic Institution, 1993-01)
      Marine biotoxins and harmful algae represent a significant and expanding threat to human health and fisheries resources throughout the U.S. This problem takes many forms, ranging from massive "red tides" or blooms of cells ...
    • The marine disposal of sewage sludge and dredge spoil in the waters of the New York Bight 

      Horne, Ralph A.; Mahler, A. J.; Rossello, R. C. (Woods Hole Oceanographic Institution, 1971-01-29)
      The dumping of sewer sludge and dredge spoil in the waters of the New York Bight and the effect of this waste disposal practice on the marine environment is reviewed. The. quantities and composition of these wastes is ...
    • Marine ecosystem dynamics and biogeochemical cycling in the Community Earth System Model [CESM1(BGC)] : comparison of the 1990s with the 2090s under the RCP4.5 and RCP8.5 scenarios 

      Moore, J. Keith; Lindsay, Keith; Doney, Scott C.; Long, Matthew C.; Misumi, Kazuhiro (American Meteorological Society, 2013-12-01)
      The authors compare Community Earth System Model results to marine observations for the 1990s and examine climate change impacts on biogeochemistry at the end of the twenty-first century under two future scenarios ...
    • The marine geochemistry of iron and iron isotopes 

      Bergquist, Bridget A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2004-09)
      This thesis addressed questions about the Fe cycle by measuring detailed profiles and transects of Fe species in the ocean and also by exploring the use of a new tracer of Fe, Fe isotopic fractionation. In the subtropical ...
    • The marine geochemistry of methane 

      Scranton, Mary Isabelle (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1977-08)
      In the highly productive coastal surface waters near Walvis Bay, methane is present in concentrations considerably above those which would be predicted from solubility equilibrium with the atmosphere. A one dimensional ...
    • The marine geochemistry of the rare earth elements 

      Baar, Hein J. W. de (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1983-09)
      Novel methods were developed for the determination of 12 of the 14 Rare Earth Elements (REE) in seawater. Initial extractions of the REE by chelating ion exchange chromatography is followed by cation exchange for removal ...
