Instabilities of an eastern boundary current with and without Large-scale Flow Influence
(Massachusetts Institute of Technology, 2011)
Eastern oceanic boundary currents are subject to hydrodynamic instability, generate small scale features that are visible in satellite images and may radiate westward into the interior, where they can be modified by the ...
Experimental studies of melting and crystallization processes in planetary interiors
(Massachusetts Institute of Technology, 2011)
Melting and crystallization processes on the Earth and Moon are explored in this thesis, and the topics of melt generation, transport, and crystallization are discussed in three distinct geologic environments: the Moon's ...
Lipid biomarkers of coral stress : calibration and exploration
(Massachusetts Institute of Technology, 2011)
Corals are increasingly threatened by warming sea surface temperatures and other anthropogenic changes. The delicate symbiosis between corals and their algal endosymbionts (zooxanthellae) is easily disrupted by thermal ...
The biogeochemistry of marine nitrous oxide
(Massachusetts Institute of Technology, 2011)
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 ...
Interactions of cadmium, zinc, and phosphorus in marine Synechococcus : field uptake, physiological and proteomic studies
(Massachusetts Institute of Technology, 2011)
A combination of uptake field studies on natural phytoplankton assemblages and laboratory proteomic and physiological experiments on cyanobacterial isolates were conducted investigating the interactions of cadmium (Cd), ...
Marine particle dynamics : sinking velocities, size distributions, fluxes, and microbial degradation rates
(Massachusetts Institute of Technology, 2011)
The sinking flux of particulate matter into the ocean interior is an oceanographic phenomenon that fuels much of the metabolic demand of the subsurface ocean and affects the distribution of carbon and other elements ...
