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 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 ...
Plutonium isotopes in the North Atlantic
(Massachusetts Institute of Technology, 1986)
The entrainment and homogenization of tracers within the cyclonic gulf stream recirculation gyre
(Massachusetts Institute of Technology, 1987)
The various distributions of tracer associated with the Northern Recirculation Gyre of the Gulf Stream (NRG) are studied to try to obtain information about the flow. An advective-diffusive numerical model is implemented ...
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 ...
Vertical flux, ecology and dissolution of radiolaria in tropical oceans : implications for the silica cycle
(Massachusetts Institute of Technology, 1982)
Radiolarians which settle through the oceanic water column were recovered from three stations (western Tropical Atlantic-Station E, central Tropical Pacific-P1 and Panama Basin-PB) using PARFLUX sediment traps in moored ...
