Chirp seismic-reflection data of USGS field activity 2014-645-FA collected in the outer Santa Barbara Channel, California, between 2014-11-12 to 2014-11-25 (ver. 2.0, March 2020)

This data release contains 43 chirp sub-bottom profiles that were collected in November of 2014 from the Catalina and Santa Cruz Basins offshore southern California by the U.S. Geological Survey Pacific and Coastal Marine Science Center. Data were collected aboard the University of California’s R/V Robert Gordon Sproul on USGS cruise 2014-645-FA. Chirp profiles were collected to assess earthquake and submarine landslide hazards offshore southern California.

Multichannel minisparker seismic-reflection data of field activity 2015-651-FA; Chatham Strait and Cross Sound, southeastern Alaska from 2015-08-03 to 2015-08-21

This data release contains high-resolution multichannel seismic (MCS) reflection data collected in August of 2015 to explore marine geologic hazards of inland waterways of southeastern Alaska. Sub-bottom profiles were acquired in the inland waters between Glacier Bay and Juneau, including Cross Sound and Chatham Strait. High-resolution seismic-reflection profiles were acquired to assess evidence for active seabed faulting and submarine landslide hazards. The data were collected aboard the US Geological Survey R/V Alaskan Gyre. The seismic-reflection data were acquired using a 500-Joule minisparker source and a 48-channel Geometrics GeoEel digital streamer. Subbottom acoustic penetration spans up to several hundreds...

Multichannel minisparker seismic-reflection data of USGS field activity 2016-616-FA collected in the Catalina Basin offshore southern California in February 2016

This data release contains 25 multichannel minisparker seismic reflection (MCS) profiles that were collected in February of 2016 from the Catalina Basin offshore southern California by the U.S. Geological Survey Pacific and Coastal Marine Science Center in cooperation with the University of Washington. Data were collected aboard the University of Washington’s R/V Thomas G. Thompson on USGS cruise 2016-616-FA. MCS profiles were collected to image the Catalina and San Clemente fault systems as well as the San Gabriel Canyon and Channel system.
