Geological and Geophysical data (sonobuoy, 12khz, airgun, gravity, 3dot5khz, uniboom, magnetics, gravitycore, chaindredge, Soutargrab, uniboom, 24channel, sidescansonar, underwatercamera, rangerange, dopplersonar, integratednavigation, radar, transitsatellite, airgunmonitor) of field activity L-5-84-SP in Vanuatu, Southern Pacific from 05/04/1984 to 06/05/1984
Location Southern Pacific
Summary physical data holdings 2400 km of 24-fold multichannel seismic reflection data were collected along 37 lines. The seismic source consisted of a tuned, 5 airgun array totaling 1426 cubic inches, pressurized to 2000 psi, towed at a depth of approximately 10 meters. Individual gun volumes were usually 148, 194, 309, 309, and 466 cubic inches. The receiver consisted of a 24 channel hydrophone streamer with 100 meter group lengths containing 60 hydrophones in each group. The near channel offset from the airguns was 297 m and far channel offset 2611 m. The data were recorded with a Gus Model HDDR-4200 recording system. Shots were fired every 50 meters and records were sampled in the field at a 2 millisecond rate prior to processing. Primary navigation was by satellite. 2548 nautical miles of bathymetric data and 2225 nautical miles of gravity data were collected.
Info derived Seismic reflection profiles, gravity, magnetics, bathymetry, side scan, lithology, underwater photographs.
Comments GIS tools on best navigation file, l-5-84-sp.071, found cumulative trackline distance to the nearest tens of kilometers is 5990 kilometers.
