Slice of History: Advanced Ocean Technology Development Platform

Each month in “Slice of History” we feature a historical photo from the JPL Archives. See more historical photos and explore the JPL Archives at https://beacon.jpl.nasa.gov/.

Advanced Ocean Technology Development Platform
Advanced Ocean Technology Development Platform — Photograph Number P-23298B

The Advanced Ocean Technology Development Platform (AOTDP) was developed at NASA’s Jet Propulsion Laboratory in the late 1970s by the Undersea Technology Program Office. The project applied space program instruments and systems to ocean exploration, mapping and resource assessment. This photo was taken in December 1980, after more than two months of engineering tests around Long Beach and Los Angeles harbors. The AOTDP shallow water test team included, from left to right, Sherry Wheelock, Don Hoff, Gary Bruner, Larry Broms, Curtis Tucker, Hal Holway, Garry Paine, Martin Orton and task manager Bill Gulizia.

The submersible vehicle test platform carried digital side-looking sonar for underwater imaging and a tow cable connecting the submersible to its companion surface ship, providing command, telemetry and power links. There was a shipboard control and data acquisition center to process and display the information gathered by the submersible, at rates of up to 250,000 bits per second. It was designed to descend as deep as 20,000 feet, but test tows were conducted at depths of about 600 feet. The project was funded by NASA and tests designed to improve the side-looking sonar instrument were sponsored by the National Oceanic and Atmospheric Administration (NOAA).
