Linear and nonlinear Rossby waves in basins both with and without a thin meridional barrier
(Massachusetts Institute of Technology, 2002)
The linear and nonlinear Rossby wave solutions are examined in homogeneous square basins on the [beta]-plane both with and without a thin meridional barrier. In the presence of the meridional barrier the basin is almost ...
Phosphate-mineral interactions and potential consequences for nutrient cycling
(Massachusetts Institute of Technology, 2008)
Biogeochemical cycling of phosphate is a key component in the overall production rate of coastal ecosystems. Mineral phases in the near-shore sediments play a significant role in the return of phosphate remineralized in ...
Plagioclase preferred orientation in the layered mylonites : evaluation of flow laws for the lower crust
(Massachusetts Institute of Technology, 2008)
We evaluate the applicability of plagioclase and gabbro flow laws by comparing predicted and observed deformation mechanisms in gabbroic shear zones. Gabbros and layered gabbro mylonites were collected from the Southwest ...
Variability of zooplankton and sea surface temperature in the Southern Ocean
(Massachusetts Institute of Technology, 2006)
Interactions between physical and biological processes in the Southern Ocean have significant impacts on local ecosystems as well as on global climate. In this thesis, I present evidence that the Southern Ocean circulation ...
Production and analysis of a Southern Ocean state estimate
(Massachusetts Institute of Technology, 2006)
A modern general circulation model of the Southern Ocean with one-sixth of a degree resolution is optimized to the observed ocean in a weighted least squares sense. Convergence toward the state estimate solution is carried ...
Reconstructing long term sediment flux from the Brooks Range, Alaska, using edge clinoforms
(Massachusetts Institute of Technology, 2004)
Laterally extensive, well-developed clinoforms have been mapped in Early Cretaceous deposits located in the northeastern 27,000 km2 of the Colville Basin, North Slope of Alaska. Using public domain 2-D seismic data, well ...
Comparison of wind stress algorithms, datasets and oceanic power input
(Massachusetts Institute of Technology, 2009)
If the ocean is in a statistically steady state, energy balance is a strong constraint, suggesting that the energy input into the world ocean is dissipated simultaneously at the same rate. Energy conservation is one of the ...
Winter mixed-layer development in the central Irminger Sea : the effect of strong, intermittent wind events
(Massachusetts Institute of Technology, 2006)
The impact of the Greenland tip jet on the wintertime mixed-layer of the southwest Irminger Sea is investigated using in-situ moored profiler data and a variety of atmospheric data sets. The mixed-layer was observed to ...
A 2 1/2 dimensional thermohaline circulation model with boundary mixing
(Massachusetts Institute of Technology, 2000)
A simple quasi-two dimensional dynamical model of Thermohaline circulation (THC) is developed, assuming that the mixing only occurs near western and eastern boundary layers. When the surface density is prescribed, the ...
Arctic Ocean circulation in an idealized numerical model
(Massachusetts Institute of Technology, 2008)
The mid-to-deep Arctic Ocean is generally characterized by a cyclonic circulation, contained along shelves and ridges. Here we analyze the general Arctic circulation using an idealized numerical model consisting of a ...
