Identifier P192SC
Alternate names P-1-92-SC,91-062
Purpose To collect high-resolution seismic-reflection data from the Hueneme and Dume submarine fans.
Description United States Geological Survey, Menlo Park, California,Geological Survey of Canada. Chief Scientist: Dave Piper. Geophysical data (GPS, 12khz, Huntec, airgun) of field activity P-1-92-SC in Santa Monica Basin, Southern California from 01/25/1992 to 02/04/1992
Location Southern California
Summary We were able to take advantage of the transit of the Canadian ship Parizeau, from Pacific to Atlantic Geoscience Centres, by using a few extra days en route to survey submarine fans. The goals were to better understand the processes that lead to the formation of sandy submarine fans and the role of sea level changes in their formation. About 850 line km of high-quality Huntec DTS and sleeve-gun reflection profiles were obtained of Hueneme, Mugu and Dume submarine fans, Santa Monica Basin, off southern California. The data showed for the first time the detailed distribution of sand bodies on a modern sandy submarine fan.
Comments Geological Survey of Canada (GSC) - USGS Coop cruise run by GSC. Dates are of data collection, not including transit to and from ports. Analog materials: Original records held at GSC, Normark has a set of copies. Digital files: navigation, bathymetry, seismic (Huntec and sleeve-gun) held by USGS. Staff information imported from InfoBank Dave Piper (GSC) - Chief Scientist Bill Normark (USGS Western Region) - Unspecified
