B -- SPECIAL STUDIES PROCESSING OF DIGITAL HIGH RESOLUTION SEISMIC REFLECTION DATA IN THE VICINITY OF THE LOS ANGELES AND LONG BEACH HARBORS, CA. SOL 00-7440-5110 DUE 071500 POC trinidad f. biando (650) 329-4176 E-MAIL: tbiando@wr.usgs.gov, tbiando@wr.usgs.gov. The U.S. Geological Survey (USGS) requires the acquisition and processing of digital high resolution seismic reflection data in the vicinity of the Los Angeles and Long Beach harbors, Ca. The survey instruments are to include a single- or dual-channel very high-resolution (1 to 4 khz) profiling system and a small airgun (15-40 cubic inches), short group interval (3 to 5 meters) 24-channel hydrophone array. Reflections profiles are to be acquired and displayed in real time, allowing the selection of new survey tracklines while underway. The contractor will be required to furnish all equipment, labor and materials necessary to accomplish the scope of work detailed. The only exception to the above is the multichannel seismic recording system. The USGS will provide a Geometrics 24-channel R-60 seismograph, MC-1 marine controller, printrex printer and two 4mm DAT tape drives. The contractor will be responsible for obtaining all necessary licenses, permits and permissions necessary to undertake the work. ThUSGS will assist the contractor in obtaining permits and permissions, but will not be responsible for any delays or problems in obtaining them. Posted 07/26/00 (W-SN478926). (0208)
