Title:
Geophysical data of field activity A-1-02-SC in Pt. Arguello to Pt. Dume from 06/14/2002 to 06/29/2002
Abstract:
United States Geological Survey, Menlo Park, California. Chief Scientists: Mike Fisher, Chris Gutmacher. Geophysical data (12khz, YoNav, GPS, Kleinsidescan, airgun, minisparker, Chirp, boomer, sparker) of field activity A-1-02-SC in Pt. Arguello to Pt. Dume from 06/14/2002 to 06/29/2002, <http://walrus.wr.usgs.gov/infobank/a/a102sc/html/a-1-02-sc.meta.html>.
Supplemental_Information:

Equipment Used -
12khz bathymetry, Code: BA12, Brand: Knudsen, Model: 320 B/R echosounder, Media: D,P (paper recorded on EPC 1086), Comments: Recorded by Yonav, usually towed at 10m depth; sometimes short-hauled to 5 m but not always fixed in program, so Yonav depths may be off by 5 m in some areas.
YoNav Ship navigation, Code: YNAV, Brand: In-house program run on PC, Media: D, Comments: Worked very reliably, few spontaneous crashes
GPS Ship navigation, Brand: CSI Wireless, Model: DGPS Max, Media: D, by Yonav program, Comments: Differential GPS- WAAS (wide-area augmentation system; v accurate)
Kleinsidescan Code: SCAN, Brand: Klein, Model: 2000, Media: D, P (paper recorded on TDU 850), Comments: Digitally recorded both 100 and 500 kHz; Sidescan fish nav, Brand: ORE, Model: Trackpoint II plus, Media: D, Comments: Recorded in ss header file and by Yonav program
airgun Seismic sound source, Code: SCAG or MCAG, Brand: "single"-channel streamer actually 2 channel SIG, multi-channel streamer ITI with seismograph and controller, Media: D by Delph (SCAG) or MCS; and P for SCAG on TDU 850), Comments: GI 35 cu.in. Sureshot failed early on so did not have cancelling of outgoing pulse. AG used with both Brand: "single"-channel and multi-channel streamers. Most of the time with SCAG, had a sleeve inserted so was about 24 cu.in. and could then be fired more rapidly.
minisparker Seismic sound source, Code: SCMS or MCMS, Brand: Streamers as for airgun, Model: SIG 2 mille, Media: D by Delph (SCMS) or MCS; and P for SCMS on TDU 850), Comments: 160J for SCMS, up to 2kJ for MCMS, but minisparker died running at full power and rep rate approved by manufacturer.
Chirp FSSB Chirp sonar Sub-bottom profiler, Code: FSSB, Brand: Edgetech, Model: FS-SB, Media: D, P (paper recorded on TDU 1200), Comments: Delph digital recording system
boomer Huntec boomer seismic sound source, Code: HUNT, Brand: Huntec, Model: Hydrosonde, Media: D, P (paper recorded on TDU 1200), Comments: Used very little in favor of chirp sonar. Delph digital recording system
sparker Huntec sparker seismic sound source, Code: HTSP, Brand: Huntec, Model: Hydrosonde, Media: D, P (paper recorded on TDU 1200), Comments: Used quite successfully after minisparker power supply blew up. Delph digital recording system
