Analysis and interpretation of tidal currents in the coastal boundary layer
(Massachusetts Institute of Technology, 1979)
Concern with the impact of human activities on the coastal region of the world's oceans has elicited interest in the so-called "coastal boundary layer"-that band of water adjacent to the coast where ocean currents adjust ...
The gravity field and plate boundaries in Venezuela
(Massachusetts Institute of Technology, 1972)
Free-air and simple Bouguer anomaly maps of the Venezuelan continental margin (from 60°W to 72°W and from 7°N to 13°N) are presented. The major features of the free-air map are: the large lows associated with the deep ...
Interactions between mantle plumes and mid-ocean ridges : constraints from geophysics, geochemistry, and geodynamical modeling
(Massachusetts Institute of Technology, 2001)
This thesis studies interactions between mid-ocean ridges and mantle plumes using geophysics, geochemistry, and geodynamical modeling. Chapter 1 investigates the effects of the Marion and Bouvet hotspots on the ultra-slow ...
Seismic scattering of low-grazing-angle acoustic waves incident on the seafloor
(Massachusetts Institute of Technology, 1998)
The goal of this thesis is to develop a methodology to interpret sound scattered from the seafloor in terms of seafloor structure and subseafloor geological properties. Specifically, this work has been directed towards the ...
Plume-lithosphere interaction : geochemical evidence from upper mantle and lower crustal xenoliths from the Kerguelen Islands
(Massachusetts Institute of Technology, 1999)
This study is a geochemical investigation of the evolution of the Kerguelen plume, on the basis of upper mantle and lower crustal xenoliths. Ultramafic xenoliths include harzburgites predominant, a lherzolite, dunites and ...
