  • The biogeochemistry of 210Pb and 210Po in fresh waters and sediments 

    Benoit, Gaboury (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1988-01)
    The focus of this work was geochemical cycling of 210Pb in lakes, including the water column, sediments, and their interactions with each other. A special goal was to elucidate processes that might influence the distribution ...
  • The biogeochemistry of cobalt in the Sargasso Sea 

    Saito, Mak A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2001-02)
    Processes that enable marine phytoplankton to acquire trace metals are fundamental to our understanding of primary productivity and global carbon cycling. This thesis explored the biogeochemistry of cobalt using analytical ...
  • Biogeochemistry of dissolved free amino acids in marine sediments 

    Henrichs, Susan M. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1980-08)
    Dissolved free amino acids (DFAA) were measured in interstitial water samples squeezed from sediments collected in a variety of depositional environments. These sediments were further characterized by measurements of ...
  • The biogeochemistry of marine nitrous oxide 

    Frame, Caitlin H. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2011-06)
    Atmospheric nitrous oxide N2O concentrations have been rising steadily for the past century as a result of human activities. In particular, human perturbation of the nitrogen cycle has increased the N2O production rates ...
  • The biogeochemistry of marine particulate trace metals 

    Ohnemus, Daniel C. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2014-02)
    Marine particles include living and non-living solid components of seawater, representing a dynamic and chemically diverse mixture of phases. Through a combination of method development, basin-scale particulate collection ...
  • Biological-physical interactions on Georges Bank : plankton transport and population dynamics of the ocean quahog, Arctica islandica 

    Lewis, Craig V. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1997-06)
    Advective losses of bank water during winter because of strong wind forcing were hypothesized to be a significant factor limiting recruitment of Georges Bank cormnunities. This hypothesis was examined using biological-physical ...
  • Biology and potential biogeochemical impacts of novel predatory flavobacteria 

    Banning, Erin C. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2010-06)
    Predatory bacteria are ubiquitous in aquatic environments and may be important players in the ecology and biogeochemistry of microbial communities. Three novel strains belonging to two genera of marine flavobacteria, ...
