Dynamics of Greenland's glacial fjords
(Massachusetts Institute of Technology, 2016)
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 ...
Hydrodynamic and morphodynamic responses to surfzone seafloor perturbations
(Massachusetts Institute of Technology, 2016)
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. ...
Submesoscale turbulence in the upper ocean
(Massachusetts Institute of Technology, 2016)
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 ...
Plan-view evolution of wave-dominated deltas
(Massachusetts Institute of Technology, 2016)
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 have ...
A scientific framework for evaluating coral reef resilience to climate change
(Massachusetts Institute of Technology, 2016)
The 21st century warming and acidification of tropical oceans will impact the structure and function of coral reef ecosystems. Consequently, conservation efforts are increasingly focused on identifying and protecting reef ...
Little Ice Age climate in the western tropical Atlantic inferred from coral geochemical proxies
(Massachusetts Institute of Technology, 2016)
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 impact natural ...
Seismic constraints on the processes and consequences of secondary igneous evolution of Pacific oceanic lithosphere
(Massachusetts Institute of Technology, 2016)
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 can ...
The biogeochemistry of lipid derived infochemical signals in the ocean
(Massachusetts Institute of Technology, 2016)
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 ...
