Marine Geophysics and Geodynamics
Computational and laboratory modeling of the physics of the solid earth,
including plate tectonics, mantle convection, mantle flow at subduction zones
and mid-ocean ridges, mid-ocean ridge morphology, evolution of the oceanic
crust, seismology, seismic tomography, magentic reversal stratigraphy, and
mantle plumes.

Volcanology and Geochemistry
Our scientists study subaerial and submarine volcanoes from a variety of
tectonic settings including island arcs, back-arc basins, mid-ocean ridges,
and oceanic islands associated with mantle plumes. Igneous petrology, high
temperature geochemistry, and volcaniclastic sedimentation are all current
areas of research.

Paleoceanography and Paleoclimatology
Paleoceanographic research focuses on paleo and environmental magnetism
of deep-sea and lake sediments, extinction and recovery of marine plankton
across the Cretaceous/Tertiary boundary, and the geochemistry and mineralogy
of deep-sea sediments.

Coastal Physical Oceanogrpahy
Research focuses on coastal circulation, primarily in and around Narragansett
Bay. Other study areas include the Delaware River and Ecuador's Rio Chone
estuary and the southern coast of Iceland. Study results have been utilized to determine
pollutant, nutrient, larval, and sediment transport, and for the calibration
of numerical flow models.
