The Chesapeake Bay bolide impact: a new view of coastal plain evolution The Chesapeake Bay bolide impact: a new view of coastal plain evolution

A spectacular geological event took place on the Atlantic margin of North America about 35 million years ago in the late part of the Eocene Epoch. Sea level was unusually high everywhere on Earth, and the ancient shoreline of the Virginia region was somewhere in the vicinity of where Richmond is today (fig. 1). Tropical rain forests covered the slopes of the Appalachians. To the east of...

A new view into the Cascadia subduction zone and volcanic arc: Implications for earthquake hazards along the Washington margin A new view into the Cascadia subduction zone and volcanic arc: Implications for earthquake hazards along the Washington margin

In light of suggestions that the Cascadia subduction margin may pose a significant seismic hazard for the highly populated Pacific Northwest region of the United States, the U.S. Geological Survey (USGS), the Research Center for Marine Geosciences (GEOMAR), and university collaborators collected and interpreted a 530-km-long wide-angle onshore-offshore seismic transect across the...

Major occurrences and reservoir concepts of marine clathrate hydrates: Implications of field evidence Major occurrences and reservoir concepts of marine clathrate hydrates: Implications of field evidence

This paper is part of the special publication Gas hydrates: relevance to world margin stability and climatic change (eds J.P. Henriet and J. Mienert). Questions concerning clathrate hydrate as an energy resource, as a factor in modifying global climate and as a triggering mechanism for mass movements invite consideration of what factors promote hydrate concentration, and what the...

Nonlinear refraction and reflection travel time tomography Nonlinear refraction and reflection travel time tomography

We develop a rapid nonlinear travel time tomography method that simultaneously inverts refraction and reflection travel times on a regular velocity grid. For travel time and ray path calculations, we apply a wave front method employing graph theory. The first-arrival refraction travel times are calculated on the basis of cell velocities, and the later refraction and reflection travel...

New seismic images of the cascadia subduction zone from cruise SO 108-ORWELL New seismic images of the cascadia subduction zone from cruise SO 108-ORWELL

In April and May 1996, a geophysical study of the Cascadia continental margin off Oregon and Washington was conducted aboard the German R/V Sonne. This cooperative experiment by GEOMAR and the USGS acquired wide-angle reflection and refraction seismic data, using ocean-bottom seismometers (OBS) and hydrophones (OBH), and multichannel seismic reflection (MCS) data. The main goal of this...
