A dark time coming to light... Declassified CIA documents shed light on secret Navy mission in Cold War December 30, 2012 - In late 1971, the Navy brought the deep-diving submersible Trieste II and several support ships out to a spot 350 miles north of Hawaii to retrieve Scripps Institution of Oceanography "instrumentation" from the ocean floor. That was the cover story.
The Trieste went to almost 36,000 feet. The Trieste II only went down to 20,000 feet (this mission only to 17,000 feet). So I really see nothing of importance here, sorry. Personally, Project Jennifer I think was much more important then this was.
