Graduate students on the PROTEUS cruise 2015.

Seismology is a powerful tool for studying structure and processes in the Earth; it is particularly successful when combined with geophysical and geochemical information. I am looking for students with quantitative skills, who are interested in interdisciplinary research. The University of Oregon’s strengths in volcanology, petrology and geochemistry, remote sensing and geodynamics are excellent compliments to these studies.

Graduate students can get involved in several projects:

Santorini: The group continues to model, integrate, and mine the seismic data from a huge data set collected fall 2015 at Santorini Volcano in the Mediterranean.  The PROTEUS experiment collected seismic data to understand the magma plumbing structure through the entire crust beneath the volcano as well as regional tectonics.  The analysis of this data involves state-of-the-art seismic travel tomography and full waveform inversion to obtained high resolution structural images.  It also includes marine geophysical (multi beam bathymetry, gravity, and magnetics) and modeling studies of the volcano and its tectonic setting.

Cascadia2020.  Image the 3D seismic structure of the Cascadia subduction zone in the region of the down dip edge of the locking zone by deploying 900 seismometers in the Oregon and southern Washington coast ranges in summer 2020 to record the deep penetrating seismic waves from the R/V Marcus Langseth source.

Galapagos plume-ridge interaction.  Test our models and refine our understanding of the physics and chemistry of these interactions by deploying 55 ocean bottom seismometers west of the Galapagos archipelago for 15 months to image mantle and lithospheric structures.
