Carbon and mineral transformations in seafloor serpentinization systems
(Massachusetts Institute of Technology, 2018)This thesis examines abiotic processes controlling the transformation and distribution of carbon compounds in seafloor hydrothermal systems hosted in ultramafic rock. These processes have a direct impact on carbon budgets ... -
The crustal structure and subsidence history of aseismic ridges and mid-plate island chains
(Massachusetts Institute of Technology, 1978) -
Flow and sediment properties influencing erosion of fine-grained marine sediments : sea floor and laboratory experiments.
(Massachusetts Institute of Technology, 1975) -
Geochemical and rheological constraints on the dynamics of the oceanic upper mantle
(Massachusetts Institute of Technology, 2007)I provide constraints on mantle convection through observations of the rheology and composition of the oceanic upper mantle. Convection cannot be directly observed, yet is a fundamental part of the plate tectonic cycle. ... -
Infragravity waves over topography: generation, dissipation, and reflection
(Massachusetts Institute of Technology, 2006)Ocean surface infragravity waves (periods from 20 to 200 s) observed along the southern California coast are shown to be sensitive to the bottom topography of the shelf region, where propagation is linear, and of the ... -
Mechanisms of turbulent mixing in the Continental Shelf bottom boundary layer
(Massachusetts Institute of Technology, 2000)The bottom boundary layer is an important dynamical region of shallow water flows. In this thesis, the problem of turbulent mixing in the coastal bottom boundary layer is investigated with a unique set of field measurements ... -
Seismic and gravitational studies of melting in the mantle's thermal boundary layers
(Massachusetts Institute of Technology, 2007)This thesis presents three studies which apply geophysical tools to the task of better understanding mantle melting phenomena at the upper and lower boundaries of the mantle. The first study uses seafloor bathymetry and ... -
Stochastic modeling of seafloor morphology
(Woods Hole Oceanographic InstitutionMassachusetts Institute of Technology, 1990)
