1. Structure of the crust beneath Lake Superior from forward modeling of large aperture seismic data

Creator:: Shay, John T.
Abstract:: Both travel times and amplitudes of large offset refracted and reflected arrivals observed during GLIMPCE (Great Lakes International Multidisciplinary Program on Crustal Evolution) along line A in Lake Superior have been modeled using two-dimensional ray tracing techniques. Forward modeling was used to iteratively refine an initial velocity model that was...

2. Seismic sequence stratigraphy and tectonic evolution of southern hydrate ridge

Creator:: Chevallier, Johanna
Abstract:: A 3D seismic volume was acquired summer 2000 over the southern end of Hydrate Ridge (FIR), an anomalously shallow ridge 100 km offshore Newport, Oregon. The survey followed a succession of scientific expeditions aimed at studying the gas hydrates present in the shallow subsurface that gave the name to the...
