Large scale oceanic circulation and fluxes of freshwater, heat, nutrients and oxygen
(Massachusetts Institute of Technology, 2000)
A new, global inversion is used to estimate the large scale oceanic circulation based on the World Ocean Circulation Experiment and Java Australia Dynamic Experiment hydrographic data. A linear inverse "box" model is used ...
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)
The seasonal and interannual variability of the West Greenland current system in the Labrador Sea
(Massachusetts Institute of Technology, 2010)
The Labrador Sea, as one of a few places of deep water formation, plays an important role in the Meridional Overturning Circulation. While the interior of the Labrador Sea, where the deepest convection takes place, is known ...
Injection and movement of Tritium-³He in the Northeastern Atlantic
(Massachusetts Institute of Technology, 1999)
This thesis describes an attempt to build a box model of the circulation in the eastern North Atlantic and to use it with transient tracer data to infere rates of ventilation in the subtropcial thermocline. The starting ...
A laboratory study of localized boundary mixing in a rotating stratified fluid
(Massachusetts Institute of Technology, 2003)
Oceanic observations indicate that abyssal mixing is localized in regions of rough topography. How locally mixed fluid interacts with the ambient fluid is an open question. Laboratory experiments explore the interaction ...
Dynamics of freshwater plumes: observations and numerical modeling of the wind-forced response and alongshore freshwater transport
(Massachusetts Institute of Technology, 1988)
A freshwater plume often forms when a river or an estuary discharges water onto the continental shelf. Freshwater plumes are ubiquitous features of the coastal ocean and usually leave a striking signature in the coastal ...
Buoyancy-driven circulation in the Red Sea
(Massachusetts Institute of Technology, 2014)
This thesis explores the buoyancy-driven circulation in the Red Sea, using a combination of observations, as well as numerical modeling and analytical method. The first part of the thesis investigates the formation mechanism ...
Temperature and salinity variability in thermohaline staircase layers
(Massachusetts Institute of Technology, 2005)
A moored profiler record from the western tropical North Atlantic provides the first continuous time series of temperature, salinity and velocity profiles in a thermohaline staircase. Variations in the intensity of layering ...
Evolution of the Irminger Current anticyclones in the Labrador Sea from hydrographic data
(Massachusetts Institute of Technology, 2006)
The continuous supply of heat and fresh water from the boundaries to the interior of the Labrador Sea plays an important role for the dynamics of the region and in particular, for the Labrador Sea Water formation. Thus, ...
