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 ...
Fluid flow and sound generation at hydrothermal vent fields
(Massachusetts Institute of Technology, 1988)
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 ...
Thermal and mechanical development of the East African Rift System
(Massachusetts Institute of Technology, 1988)
The deep basins, uplifted flanks, and volcanoes of the Western and Kenya rift systems have developed along the western and eastern margins of the 1300 km-wide East African plateau. Structural patterns deduced from field, ...
Cenozoic deep-water agglutinated foraminifera in the North Atlantic
(Massachusetts Institute of Technology, 1988)
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 ...
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 ...
Mass, heat and nutrient fluxes in the Atlantic Ocean determined by inverse methods
(Massachusetts Institute of Technology, 1988)
Inverse methods are applied to historical hydrographic data to address two aspects of the general circulation of the Atlantic Ocean. The method allows conservation statements for mass and other properties, along with a ...
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, ...
