  • Optimal bioeconomic management of changing marine resources 

    Moberg, Emily A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2016-09)
    Marine populations are increasingly subjected to changing conditions whether through harvest or through broad-scale habitat change. Historically, few models have accounted for such trends over time, and even fewer have ...
  • When an eddy encounters shelf-slope topography 

    Cherian, Deepak A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2016-09)
    Eddies in the ocean move westwards. Those shed by western boundary currents must then interact with continental shelf-slope topography at the western boundary. The presence of other eddies and mean lows complicates this ...
  • Little Ice Age climate in the Western Tropical Atlantic inferred from coral geochemical proxies 

    Alpert, Alice (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2016-09)
    Paleoclimate archives place the short instrumental record of climate variability in a longer temporal context and allow better understanding of the rate, nature and extent by which anthropogenic warming will i ...
  • Graphical model driven methods in adaptive system identification 

    Yellepeddi, Atulya (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2016-09)
    Identifying and tracking an unknown linear system from observations of its inputs and outputs is a problem at the heart of many different applications. Due to the complexity and rapid variability of modern systems, there ...
  • Mechanisms for enhanced turbulence in the Drake Passage region of the Southern Ocean 

    Merrifield, Sophia T. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2016-06)
    The Southern Ocean is one of the most energetic regions of the world ocean due to intense winds and storm forcing, strong currents in the form of the Antarctic Circumpolar Current (ACC) interacting with steep topography, ...
  • Dynamics of Greenland’s glacial fjords 

    Jackson, Rebecca H. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2016-06)
    Glacial fjords form conduits between glaciers of the Greenland Ice Sheet and the North Atlantic. They are the gateways for importing oceanic heat to melt ice and for exporting meltwater into the ocean. Submarine melting ...
  • Vortices in sinusoidal shear, with applications to Jupiter 

    Vilasur Swaminathan, Rohith (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2016-06)
    In this thesis, we have studied the existence of vortex steady states in a sinusoidal background shear flow in a 1.75 layer quasi-geostrophic model. Trying to find vortex structures by integrating the Hamiltonian system ...
  • Microbial cycling of marine high molecular weight dissolved organic matter 

    Sosa, Oscar A. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2016-06)
    Microorganisms play a central role mediating biogeochemical cycles in the ocean. Marine dissolved organic matter (DOM) – a reservoir of organic solutes and colloids derived from plankton is a major source of carbon, ...
  • Hydrodynamic and morphodynamic responses to surfzone seafloor perturbations 

    Moulton, Melissa (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2016-06)
    Holes and channels were excavated in the surf zone on an ocean beach near Duck, NC, and observations of the subsequent evolution of waves, currents, and the modified seafloor were used to investigate nearshore dynamics. ...
  • Molecular determination of marine iron ligands by mass spectrometry 

    Boiteau, Rene M. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2016-02)
    Marine microbes produce a wide variety of metal binding organic ligands that regulate the solubility and availability of biologically important metals such as iron, copper, cobalt, and zinc. In marine environments where ...
  • Seismic constraints on the processes and consequences of secondary igneous evolution of Pacific oceanic lithosphere 

    Feng, Helen S.-H. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2016-02)
    This thesis examines the structure of Pacific oceanic lithosphere that has been modified by post-formation magmatism in order to better understand the processes of secondary magmatic evolution of the lithosphere, which ...
  • The biogeochemistry of lipid derived infochemical signals in the ocean 

    Edwards, Bethanie R. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2016-02)
    The role of oxylipins in ocean biogeochemistry was investigated using microcosm amendment experiments, environmental lipidomics, and culture based studies. Oxylipins are a bioactive class of secondary metabolites produced ...
  • Behavioral responses of invertebrate larvae to water column cues 

    Wheeler, Jeanette D. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2016-02)
    Many benthic marine invertebrates have two-phase life histories, relying on planktonic larval stages for dispersal and exchange of individuals between adult populations. Historically, larvae were considered passive ...
  • Defining the ecological and physiological traits of phytoplankton across marine ecosystems 

    Alexander, Harriet (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2016-02)
    Marine phytoplankton are central players in the global carbon cycle, responsible for nearly half of global primary production. The identification of the factors controlling phytoplankton ecology, physiology, and, ultimately, ...
  • Plan-view evolution of wave-dominated deltas 

    Nienhuis, Jaap H. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2016-02)
    Ocean waves are a powerful sediment transport mechanism in the coastal zone. This thesis investigates how waves shape deltaic landforms and how small scale river mouth processes affect large-scale delta morphology. I ...
  • Late Quaternary climate variability and terrestrial carbon cycling in tropical South America 

    Fornace, Kyrstin L. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2016-02)
    Characterizing global and regional climate variability and climate-carbon cycle interactions in the past provides critical context for evaluating present and future climate trends. In this thesis, I use stable isotope ...
  • Navigation and manipulation for autonomous underwater dismantling of offshore structures 

    Welch, Christian L. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2015-09)
    The dismantling of offshore structures, known as decommissioning, is a complex task in the oil and gas industry, driven by strict environmental standards. As the environments in which decommissioning is necessary become ...
  • Distributed autonomy and formation control of a drifting swarm of autonomous underwater vehicles 

    Rypkema, Nicholas R. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2015-09)
    Recent advances in autonomous underwater vehicle (AUV) technology have led to their wide-spread acceptance and adoption for use in scientific, commercial, and defence applications in the underwater domain. At the same time, ...
  • Real time bottom reverberation simulation in deep and shallow ocean environments 

    Miller, Thomas E. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2015-09)
