Chief Scientists: Jack Kindinger, John Suter. Geophysical data (Geopulse, 3dot5khz, navigation) of field activity ACAD87-2,LG1 (A-21-87-LA) in Chandeleur Islands, Louisiana, Mississippi, Alabama, Gulf of Mexico,North America, North Atlantic from 06/14/1987 to 06/26/1987, http://walrus.wr.usgs.gov/infobank/a/a2187la/html/a-21-87-la.meta.html. Purpose: These data and information are intended for science researchers, students from elementary through college, policy makers, and general public. Supplemental_Information: Equipment Used - Geopulse ORE bomer, Benthos 10 element hydrophone, EPC 3200 recorder, ORE 5210 receiver, ORE 5420 A power supply 3dot5khz ORE 3.5 kHz subbottom profiler with ORE 140 transceiver navigation Northstar 6000 Loran, Texas Instruments Silent 700, EPC delay box Similar information is available for thousands of other USGS/CMG-related Activities. If known, available are Activity-specific navigation, gravity, magnetics, bathymetry, seismic, and sampling data; track maps; and equipment information; as well as summary overviews, crew lists, and information about analog materials.
