Laboratory analysis of restrenghtening on simulated faults
(Massachusetts Institute of Technology, 1999)
Seismic data show that stress drop increases with the logarithm of earthquake recurrence interval (1-5 MPa per decade time). If stress drop is taken as a proxy for fault strength, then the data suggest that faults restrengthen ...
Modeling the impact of atmospheric moisture transport on global ice volume
(Massachusetts Institute of Technology, 2004)
Following Milankovitch's original hypothesis most model studies of changes in global ice volume on orbital time scales have focused on the impact of ablation on ice sheet mass balance. In most cases, poleward moisture flux ...
Anisotropy and deformation in the Earth's mantle : seismological observations, geodynamical models, and laboratory experiments
(Massachusetts Institute of Technology, 2006)
In this thesis I report the results of several studies of elastic anisotropy and deformation in the Earth's mantle, using shear wave splitting measurements, numerical models of geodynamical processes, and laboratory ...
Atmospheric propagation effects on radio interferometry
(Massachusetts Institute of Technology, 1986)
The production of non-methane hydrocarbons by marine plankton
(Massachusetts Institute of Technology, 2001)
The oceans are a small source of non-methane hydrocarbons (NMHC), a suite of volatile organics whose chemical destruction mechanism by reaction with hydroxyl radical can significantly affect the oxidation capacity of the ...
Quantifying channelized submarine depositional systems from bed to basin scale
(Massachusetts Institute of Technology, 2004)
The challenges of directly observing active turbidity currents necessitates the consideration of preserved deposits for deciphering the behavior of these systems. In this thesis, I take advantage 3-D subsurface seismic ...
Problems with a localized nature in exploration seismology
(Massachusetts Institute of Technology, 2017)
A wide range of problems in seismology have a localized nature. Examples include inversion for time-lapse change, salt boundary position and Amplitude or Phase Versus Angle (AVA/PVA). With increasing computational power, ...
Experimental and seismological constraints on the rheology, evolution, and alteration of the lithosphere at oceanic spreading centers
(Massachusetts Institute of Technology, 2007)
Oceanic spreading centers are sites of magmatic, tectonic, and hydrothermal processes. In this thesis I present experimental and seismological constraints on the evolution of these complex regions of focused crustal accretion ...
Emergent geometries of groundwater-fed rivers
(Massachusetts Institute of Technology, 2017)
Groundwater-fed rivers form stunning geometries over a range of scales. These rivers grow as water from an underground aquifer reemerges and erodes the overlying topography. Both the aquifer and the overlying topography ...
Attribution of stratospheric ozone change and associated climate impacts
(Massachusetts Institute of Technology, 2018)
Recognition of stratospheric ozone depletion as a significant global danger sparked the landmark international agreement of the Montreal Protocol to control the production of ozone depleting substances (ODSs). There are ...
