Field Activity Details for field activity 1987-014-FA

Other ID: AUTEC TEST #003W01

Status: Completed

Organization(s): USGS, Woods Hole Coastal and Marine Science Center

Funding Program(s):

Principal Investigator(s): William Schwab

Affiliate Investigator(s): Kevin O'Toole, PMG

Information Specialist(s):

Data Type(s): Imagery: Photo, Imagery: Video, Sampling: Geology, Sonar: Sidescan

Scientific Purpose/Goals: 1) Collect a data set using the SeaMARC 1B sidescan sonar and ARGO video systems that would allow the construction of a high-resolution geologic map of a segment of sea floor of the Tongue of the Ocean (TOTO), including part of the AUTEC range. 2) Conduct engineering studies of cable and vehicle dynamics for various velocities, configurations, and modes of operation. 3) Test a 100 kHz sidescan sonar system and a Charge Couple Device (CCD) electronic still camera, both mounted on ARGO. 4) Test recently upgraded ALLNAV navigation system.


Start Date: 1987-04-17

Start Port/Location: Port Everglades, FL

End Date: 1987-05-01

End Port/Location: Port Everglades, FL

Equipment Used: ARGO, SeaMARC sidescan sonar system

Information to be Derived: Sea floor map;

Summary of Activity and Data Gathered: Lack of SeaMarc 1B digital data due to computer failure; only analog (paper) data exists. Still camera, video system and sidescan sonar worked well.
