Thermally driven circulation
(Massachusetts Institute of Technology, 1987)
Several problems connected by the theme of thermal forcing are addressed herein. The main topic is the stratification and flow field resulting from imposing a specified heat flux on a fluid that is otherwise confined to a ...
Dynamics of the equatorial undercurrent and its determination
(Massachusetts Institute of Technology, 1988)
This study focuses on the zonal weakening, eastern termination and seasonal variations of the Atlantic equatorial undercurrent (EUC). The main and most original contribution of the dissertation is a detailed analysis of ...
The tectonics and three-dimensional structure of spreading centers--microearthquake studies and tomographic inversions
(Massachusetts Institute of Technology, 1987)
Two-thirds of the Earth's surface has been formed along a global system of spreading centers that are presently manifested in several different structural forms, including the classic rift valley of the Mid-Atlantic Ridge, ...
Prediction of continental shelf sediment transport using a theoretical model of the wave-current boundary layer
(Massachusetts Institute of Technology, 1987)
This thesis presents an application of the Grant-Madsen-Glenn bottom boundary layer model (Grant and Madsen, 1979; Glenn and Grant, 1987) to predictions of sediment transport on the continental shelf. The analysis is a ...
Particle flux in the Western Black Sea in the present and over the last 5,000 years : temporal variability, sources, transport mechanisms
(Massachusetts Institute of Technology, 1987)
Fluid flow and sound generation at hydrothermal vent fields
(Massachusetts Institute of Technology, 1988)
Helium and lead isotope geochemistry of oceanic volcanic rocks from the East Pacific and South Atlantic
(Massachusetts Institute of Technology, 1987)
The isotopic evolution of helium and lead in the Earth is coupled by virtue of their common radioactive parents uranium and thorium. The isotopic signatures in oceanic volcanic rocks provide constraints on the temporal ...
Application of Seasat altimetry to tectonic studies of fracture zones in the Southern oceans
(Massachusetts Institute of Technology, 1987)
Gravity derived from Seasat altimetry has provided a means of estimating seafloor topography and its compensation, which in turn can be used to understand the evolution of oceanic lithosphere. In the first study, the ...
The influence of geothermal sources on deep ocean temperature, salinity, and flow fields
(Massachusetts Institute of Technology, 1988)
This thesis is a study of the effect of geothermal sources on the deep circulation, temperature and salinity fields. In Chapter 1 background material is given on the strength and distribution of geothermal heating. In ...
Observations and modelling of deep equatorial currents in the central Pacific
(Massachusetts Institute of Technology, 1988)
Analysis of vertical profiles of absolute horizontal velocity collected in January 1981, February 1982 and April 1982 in the central equatorial Pacific as part of the Pacific Equatorial Ocean Dynamics (PEQUOD) program, ...
