Adaptive error estimation in linearized ocean general circulation models
(Massachusetts Institute of Technology, 1999)
Data assimilation methods, such as the Kalman filter, are routinely used in oceanography. The statistics of the model and measurement errors need to be specified a priori. In this study we address the problem of estimating ...
Surface and bottom boundary layer dynamics on a shallow submarine bank : southern flank of Georges Bank
(Massachusetts Institute of Technology, 1999)
The thesis investigates the circulation at a 76-m deep study site on the southern flank of Georges Bank, a shallow submarine bank located between the deeper Gulf of Maine and the continental slope. Emphasis is placed on ...
Stochastic modeling of seafloor morphology
(Woods Hole Oceanographic InstitutionMassachusetts Institute of Technology, 1990)
Wind-driven circulation on a shallow, stratified shelf
(Massachusetts Institute of Technology, 1999)
A detailed examination of the development of a deep convection event observed in the Greenland Sea in 1988-89 is carried out through a combination of modeling, scale estimates, and data analysis. We develop a prognostic ...
Steady models of arctic shelf-basin exchange
(Massachusetts Institute of Technology, 1998)
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 ...
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 ...
The fluvial geochemistry of the rivers of Eastern Siberia and implications for the effect of climate on weathering
(Massachusetts Institute of Technology, 1998)
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 ...
Multiple equilibria and low-frequency variability of wind-driven ocean models
(Massachusetts Institute of Technology, 1998)
