To collect 300 nautical miles of seismic reflection and side scan sonar data at selected locations along the Southern California coast for the U.S. Army Coastal Engineering Research Center for the purpose of selecting tentative core locations and correlating seismic data with cores when collected to delineate sand resources.
Description
Woodward-Clyde Consultants,United States Army Coastal Engineering Research Center. Chief Scientist: Jan Rietman. Geophysical data (rangerange, bathymetry, Kleinsidescan, 3dot5khz, uniboom) of field activity P-2-79-SC in Offshore Oceanside, La Jolla, Mission Beach, and San Diego, Southern California from 10/15/1979 to 11/06/1979
Location
Southern California
Summary
A total of 300 nautical miles of surveying were proposed for four areas (offshore Oceanside, La Jolla, Mission Beach, and San Diego) and the interconnecting lines. The survey area extended offshore from the seaward limit of breaking waves to a water depth of about 250 ft. The actual shoreline limit of survey lines varied between water depths of 20 to 30 ft depending on weather and shoreline conditions. Where kelp beds prevented survey operations, it was necessary to alter or eliminate some of the proposed survey lines. The kelp bed areas were not considered as viable locations of offshore sand resources because kelp beds require an exposed bedrock or cobble bottom with only sparce sand overburden. The survey plan included simultaneous data collection from the following systems along each line of the survey: navigation system with track plotter, fathometer, side scan sonar, tuned transducer, and high resolution subbottom profiler.
