First Images and Orientation of Fine Structure from a 3-D Seismic Oceanography Data Set
Contributor:Holbrook, W. Steven; Blacic, Tanya M.
We present 3-D images of ocean fine structure from a unique industry-collected 3-D multichannel seismic dataset from the Gulf of Mexico that includes expendable bathythermograph casts for both swaths. 2-D processing reveals ...
Seismic Imaging of a Thermohaline Staircase in the Western Tropical North Atlantic
Contributor:Fer, Ilker; Nandi, Papia; Holbrook, W. Steven; Schmitt, Raymond W.; Páramo, Pedro
Multichannel seismic data acquired in the Lesser Antilles in the western tropical North Atlantic indicate that the seismic reflection method has imaged an oceanic thermohaline staircase. Synthetic acoustic modeling using ...
Testing Waveform Predictions of 3D Velocity Models Against Two Recent Los Angeles Earthquakes
Contributor:Lee, En Jui; Chen, Po; Jordan, Thomas H.
Nearly half of the national seismic risk is located in Southern California, and about one-fourth is concentrated in Los Angeles County alone (Federal Emergency Management Agency [FEMA], 2000). To assess the seismic hazards ...
