Summary for Field Activity Number 1987-014-FA

Alternate Leg ID: AUTEC TEST #003W01

Area of Operations: Tongue of the Ocean, Andros Island, AUTEC Weapons Range, Bahamas, North America, North Atlantic

Dates: April 17, 1987 to May 01, 1987

Objectives: 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.

Type of Activity: Sea floor mapping

Information to be derived: Sea Floor Map

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