Crustal melting in the Himalayan orogen : field, geochemical and geochronological studies in the Everest region, Nepal
(Massachusetts Institute of Technology, 2003)
A combination of field studies and geochemical techniques were used to investigate the timing and processes involved in leucogranite generation in the Everest region of the Himalayan orogen. Geochemical investigations ...
Mechanisms and variability of salt transport in partially-stratified estuaries
(Massachusetts Institute of Technology, 2000)
The variability of salt transport determines the variation of the length of the salinity intrusion and the large-scale density gradient in an estuary. This thesis contains three studies that address salt transport and the ...
The influence of a steady baroclinic deep ocean on the shelf
(Massachusetts Institute of Technology, 1988)
The upper ocean response to the monsoon in the Arabian Sea
(Massachusetts Institute of Technology, 2000)
Estimation of the upper ocean heat budget from one year of observations at a moored array in the north central Arabian Sea shows a rough balance between the horizontal advection and time change in heat when the one-dimensional ...
Steady models of arctic shelf-basin exchange
(Massachusetts Institute of Technology, 1998)
Surface-cycling of rhenium and its isotopes
(Massachusetts Institute of Technology, 2009)
The application of elemental and isotopic metal palaeoredox tracers to the geologic past rests on an understanding of modern metal cycles. This study reevaluates the surface-cycling of Mo and Re in near-surface reservoirs. ...
Analysis of certain inviscid flows on the beta plane
(Massachusetts Institute of Technology, 1986)
Occultation astronomy and instrumentation : studies of the Uranian upper atmosphere
(Massachusetts Institute of Technology, 1989)
The biogeochemistry of marine nitrous oxide
(Massachusetts Institute of Technology, 2011)
Atmospheric nitrous oxide N₂O concentrations have been rising steadily for the past century as a result of human activities. In particular, human perturbation of the nitrogen cycle has increased the N₂O production rates ...
Streams, stromatolites and the geometry of growth
(Massachusetts Institute of Technology, 2011)
This collection of papers is about recognizing common geometric features in the dynamics shaping diverse phenomena in the natural world. In particular, we focus on two systems which grow in response to a diffusive flux. ...
