HOW MEN LIVED AND WORKED UNDER THE SEA DURING THE SEALAB II PROJECT.
Originally a public domain film from the National Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.
The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

SEALAB I, II, and III were experimental underwater habitats developed by the United States Navy in the 1960s to prove the viability of saturation diving and humans living in isolation for extended periods of time. The knowledge gained from the SEALAB expeditions helped advance the science of deep sea diving and rescue, and contributed to the understanding of the psychological and physiological strains humans can endure...
SEALAB II was launched in 1965, and unlike SEALAB I, it included hot showers and refrigeration. It was placed in the La Jolla Canyon off the coast of Scripps Institution of Oceanography/UCSD, in La Jolla, California, at a depth of 205 feet (62 m). On August 28, 1965, the first of three teams of divers moved into what became known as the "Tilton Hilton" (Tiltin' Hilton, because of the slope of the landing site).
Each team spent 15 days in the habitat, but aquanaut/astronaut Scott Carpenter remained below for a record 30 days. In addition to physiological testing (described in the book by Radloff & Helmreich), the divers tested new tools, methods of salvage, and an electrically heated drysuit. They were aided by a bottlenose dolphin named Tuffy from the United States Navy Marine Mammal Program. Aquanauts and Navy trainers attempted, with mixed results, to teach Tuffy to ferry supplies from the surface to SEALAB or from one diver to another, and to come to the rescue of an aquanaut in distress. There were plans for Tuffy also to take part in SEALAB III.
A sidenote from SEALAB II was a congratulatory telephone call that was arranged for Carpenter and President Lyndon B. Johnson. Carpenter was calling from a decompression chamber with helium gas replacing nitrogen, so Carpenter sounded unintelligible to operators. The tape of the call circulated for years among Navy divers before it was aired on National Public Radio in 1999.
In 2002, a group of researchers from the Scripps Institution of Oceanography's High Performance Wireless Research and Education Network boarded the MV Kellie Chouest and used a Scorpio ROV to find the site of the SEALAB habitat. This expedition was the first return to the site since the habitat was moved...
