Seismic and magnetic constraints on the strucutre of upper oceanic crust and fast and slow spreading ridges
(Massachusetts Institute of Technology, 1998)
The upper ocean crust contains a comprehensive record of the shallow geological processes active along the world's mid-ocean ridge system. This thesis examines the magnetic and seismic structure of the upper crust at two ...
The fluvial geochemistry of the rivers of Eastern Siberia and implications for the effect of climate on weathering
(Massachusetts Institute of Technology, 1998)
Stochastic modeling of seafloor morphology
(Woods Hole Oceanographic InstitutionMassachusetts Institute of Technology, 1990)
A qualitative and quantitative study of the distribution of pelagic sediment in the Atlantic Basin
(Massachusetts Institute of Technology, 1997)
Pelagic sedimentation is the primary modifier of topography generated by ridge-associated volcanic and tectonic processes. This thesis represents an effort to understand the processes of, and the general distribution of, ...
Generation and maintenance of recirculations by Gulf Stream instabilities
(Massachusetts Institute of Technology, 1999)
This thesis studies the problems of generation and maintenance of recirculations by Gulf Stream instabilities. Observations show that the horizontal structure of the jet and its recirculations suffer significant changes ...
Cooling and internal waves on the Continental Shelf
(Massachusetts Institute of Technology, 1998)
Dynamics of global ocean heat transport variability
(Massachusetts Institute of Technology, 1999)
A state-of-the-art, high-resolution ocean general circulation model is used to estimate the time-dependent global ocean heat transport and investigate its dynamics. The north-south heat transport is the prime manifestation ...
Diapycnal advection by double diffusion and turbulence in the ocean
(Massachusetts Institute of Technology, 1999)
Observations of diapycnal mixing rates are examined and related to diapycnal advection for both double-diffusive and turbulent regimes. The role of double-diffusive mixing at the site of the North Atlantic Tracer Release ...
Multiple equilibria and low-frequency variability of wind-driven ocean models
(Massachusetts Institute of Technology, 1998)
Assessment of mesoscale eddy parameterizations for coarse resolution ocean models
(Massachusetts Institute of Technology, 1999)
Climate simulation with numerical oceanic models requires a proper parameterization scheme in order to represent the effects of unresolved mesoscale eddies. Even though a munber of schemes have been proposed and some have ...
