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. ...
A radiocarbon method and multi-tracer approach to quantifying groundwater discharge to coastal waters
(Massachusetts Institute of Technology, 2003)
Groundwater discharge into estuaries and the coastal ocean is an important mechanism for the transport of dissolved chemical species to coastal waters. Because many dissolved species are present in groundwater in concentrations ...
Structure and mechanics of the subducted Gorda Plate : constrained by afterslip simulations and scattered seismic waves
(Massachusetts Institute of Technology, 2021)
Subduction zones host the greatest earthquakes on earth and pose great threat to human society. The largest slip in megathrust earthquakes often occurs in the 10-50 km depth range, yet seismic imaging of the material ...
