  • 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)
    Due to the costs involved and time required to perform experiments at sea, it is important to provide accurate simulations of the ocean environment. Using the ray tracing code, BELLHOP, the Mission Oriented Operating ...
  • Hydrographic structure of overflow water passing through the Denmark Strait 

    Mastropole, Dana M. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2015-09)
    Denmark Strait Overflow Water (DSOW) constitutes the densest portion of North Atlantic Deep Water, which feeds the lower limb of the Atlantic Meridional Overturning Circulation (AMOC). As such, it is critical to understand ...
  • The choreography of belonging : toothed whale spatial cohesion and acoustic communication 

    Macfarlane, Nicholas B. W. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2016-02)
    To maintain the benefits of group membership, social animals need mechanisms to stay together and reunite if separated. This thesis explores the acoustic signals that dolphins use to overcome this challenge and mediate ...
  • Chemical, isotopic, and temporal variations during crustal differentiation : insights from the Dariv Igneous Complex, Western Mongolia 

    Bucholz, Claire E. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2016-02)
    Fractional crystallization of mantle-derived basaltic melts is a critical process in producing a compositionally stratified continental crust characterized by a silicic upper crust and a mafic lower crust. This thesis ...
  • Seasonal and interannual variability in the hydrology and geochemistry of an outlet glacier of the Greenland Ice Sheet 

    Linhoff, Benjamin S. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2016-02)
    In the spring and summer within the ablation zone of the Greenland Ice Sheet (GrIS), meltwater drains to the ice sheet bed through an evolving network of efficient channelized and inefficient distributed drainage systems. ...
  • Submesoscale turbulence in the upper ocean 

    Callies, Joern (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2016-02)
    Submesoscale flows, current systems 1–100 km in horizontal extent, are increasingly coming into focus as an important component of upper-ocean dynamics. A range of processes have been proposed to energize submesoscale ...
  • 2014 program ot study : climate physics and dynamics 

    Provenzale, Antonello; Ferrari, Raffaele; Flierl, Glenn R. (Woods Hole Oceanographic Institution, 2015-09)
    From the Preface: The 2014 Geophysical Fluid Dynamics Summer Study Program started on June 16th, with the topic of Climate Physics and Dynamics. The topic proved very timely and attracted an unprecedented number of ...
  • Investigating the evolution and formation of coastlines and the response to sea-level rise 

    Ortiz, Alejandra C. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2015-09)
    To understand how waves and sea level shape sandy shoreline profiles, I use existing energetics-based equations of cross-shore sediment flux to describe shoreface evolution and equilibrium profiles, utilizing linear Airy ...
  • Hydrodynamics of a multiple tidal inlet system : Katama Bay, Martha’s Vineyard, MA 

    Orescanin, Mara M. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2015-09)
    Observations, theoretical models, and a numerical model (ADCIRC) are used to investigate the effects of tides, waves, bay bathymetry, and changing inlet geometry on the hydrodynamics of the multiple-inlet Katama system, ...
  • Evolutionary demography of structured two-sex populations and sex ratios 

    Shyu, Esther (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2015-09)
    Males and females may differ in stage-specific survival, maturation, fertility, or mating availability. These demographic differences, in turn, affect population growth rates, equilibrium structure, and evolutionary ...
  • Physical control of the distributions of a key Arctic copepod in the northeast Chukchi Sea 

    Elliott, Stephen M. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2015-06)
    The copepod Calanus glacialis is one of the most important zooplankton taxa in the Arctic shelf seas where it serves as a key grazer, predator, and food source. Its summer distribution and abundance have direct effects ...
  • Strong wind events across Greenland’s coast and their influence on the ice sheet, sea ice and ocean 

    Oltmanns, Marilena (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2015-06)
    In winter, Greenland’s coastline adjacent to the subpolar North Atlantic and Nordic Seas is characterized by a large land-sea temperature contrast. Therefore, winds across the coast advect air across a horizontal temperature ...
