  • Ciliate micrograzer dynamics of the New England Shelf 

    Brownlee, Emily F. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2017-06)
    Protists play important roles in grazing and nutrient recycling, but quantifying these roles has been hindered by difficulties in collecting, culturing, and observing these often-delicate cells. During long-term deployments ...
  • Studies of lateral dispersion in the ocean 

    Sundermeyer, Miles A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1998-09)
    This thesis is written in two parts. The first part deals with the problem oflateral dispersion due to mesoscale eddies in the open ocean, and the interaction between the mesoscale strain and horizontal diffusion on ...
  • A model of the temporal and spatial distribution of carbon monoxide in the mixed layer 

    Kettle, A. James (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1994-06)
    A field experiment demonstrated the presence of a diurnal cycle in the concentration of carbon monoxide ([CO]) in the upper ocean at the BATS site. A series of laboratory experiments and numerical simulations were carried ...
  • Instabilities and radiation of thin, baroclinic jets 

    Talley, Lynne D. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1982-06)
    Oceanic fluctuations are dependent on geographical location. Near intense currents, the eddy field is highly energetic and has broad meridional extent. It is likely that the energy arises from instabilities of the intense ...
  • Tidal distortion in shallow estuaries 

    Speer, Paul E. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1984-03)
    The offshore tide becomes distorted as it propagates into shallow inlet/estuarine systems. Time asymmetries develop in the rise and fall of sea surface with consequent time and magnitude asymmetries in tidal currents. ...
  • Capturing dynamics of marine inorganic carbon fluxes from diurnal to decadal timescales 

    Chu, Sophie N. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2017-02)
    The marine carbon cycle plays an important role in regulating Earth’s climate. The vastness of the open ocean and the large variability in the coastal ocean provide obstacles to accurately quantify storage and transport ...
  • Spatiotemporal population genomics of marine species : invasion, expansion, and connectivity 

    Bors, Eleanor K. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2017-02)
    Every genome tells a story. This dissertation contains four such stories, focused on shared themes of marine population dynamics and rapid change, with an emphasis on invasive marine species. Biological invasions are ...
  • Geochemical controls on the distribution and composition of biogenic and sedimentary carbon 

    Estes, Emily R. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2017-02)
    Organic carbon (OC) preserved in marine sediments acts as a reduced carbon sink that balances the global carbon cycle. Understanding the biogeochemical mechanisms underpinning the balance between OC preservation and ...
  • The remineralization of marine organic matter by diverse biological and abiotic processes 

    Collins, James R. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2017-02)
    While aerobic respiration is typically invoked as the dominant mass-balance sink for organic matter in the upper ocean, many other biological and abiotic processes can degrade particulate and dissolved substrates on ...
  • Geophysical and geochemical constraints on the evolution of oceanic lithosphere from formation to subduction 

    Horning, Gregory W. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2017-02)
    This thesis investigates the evolution of the oceanic lithosphere in a broad sense from formation to subduction, in a focused case at the ridge, and in a focused case proximal to subduction. In general, alteration of the ...
  • Reconstructing deglacial ocean ventilation using radiocarbon : data and inverse modeling 

    Zhao, Ning (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2017-02)
    Significant changes occurred during the last deglaciation (roughly 10-20 thousand years (ka) before present) throughout the climate system. The ocean is a large reservoir of carbon and heat, however, its role during the ...
  • Linking microbial metabolism and organic matter cycling through metabolite distributions in the ocean 

    Johnson, Winifred M. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2017-02)
    Key players in the marine carbon cycle are the ocean-dwelling microbes that fix, remineralize, and transform organic matter. Many of the small organic molecules in the marine carbon pool have not been well characterized ...
  • The cobalt cycle in the Tropical Pacific Ocean 

    Hawco, Nicholas J. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2017-02)
    Although over a dozen elements are needed to support phytoplankton growth, only a few are considered to be growth-limiting. As the central atom in vitamin B12, cobalt is crucial for metabolism, but its status as a limiting ...
  • Coral reef soundscapes : spatiotemporal variability and links to species assemblages 

    Kaplan, Maxwell B. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2017-02)
    Coral reefs are biodiverse ecosystems that are at risk of degradation as a result of environmental changes. Reefs are constantly in a state of flux: the resident species assemblages vary considerably in space and time. ...
  • Understanding terrestrial organic carbon export : a time-series approach 

    Hemingway, Jordon D. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2017-02)
    Terrestrial organic carbon (OC) erosion, remineralization, transport through river networks, and burial in marine sediments is a major pathway of the global carbon cycle. However, our ability to constrain these processes ...
  • Novel analytical strategies for tracing the organic carbon cycle in marine and riverine particles 

    Rosengard, Sarah Z. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2017-02)
    Particulate organic carbon (POC) in the ocean and mobilized by rivers on land transfers ~0.1% of global primary productivity to the deep ocean sediments. This small fraction regulates the long-term carbon cycle by removing ...
  • Dynamics of North Atlantic western boundary currents 

    Le Bras, Isabela A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2017-02)
    The Gulf Stream and Deep Western Boundary Current (DWBC) shape the distribution of heat and carbon in the North Atlantic, with consequences for global climate. This thesis employs a combination of theory, observations ...
  • Ecosystem metabolism in salt marsh tidal creeks and ponds : applying triple oxygen isotopes and other gas tracers to novel environments 

    Howard, Evan M. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2017-02)
    Salt marshes are physically, chemically, and biologically dynamic environments found globally at temperate latitudes. Tidal creeks and marshtop ponds may expand at the expense of productive grass-covered marsh platform. ...
