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 ...
The response of the Red Sea to a strong wind jet near the Tokar Gap in summer
(Massachusetts Institute of Technology, 2011)
Remote sensing and in situ observations are used to investigate the ocean response to the Tokar Wind Jet in the Red Sea. The wind jet blows down the pressure gradient through the Tokar Gap on the Sudanese coast, at about ...
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 ...
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 ...
Quantifying overwash flux in barrier systems : an example from Martha's Vineyard, Massachusetts, USA
(Massachusetts Institute of Technology, 2011)
Coastal barriers are particularly susceptible to the predicted effects of accelerated of sea-level rise and the potential for increased impacts of intense storms. Over centennial scales, barriers are maintained via overtopping ...
