https://peertube.dngr.us/videos/watch/24f59948-97b0-49f0-8393-2b58f9fb457a Featuring Dr. H. David Baldridge who accumulated a great deal of data about shark attacks and wrote the book "Shark Attack" (1978), as well as other experts, this U.S. Navy-produced film SHARKS: THE DANGER IN THE SEA dates to the 1970s and may very well have been inspired by the release of the film JAWS. The film focuses on shark attacks and the Navy's efforts to combat them using shark repellant. Stuart Springer appears at the 5:00 mark, discussing the development of WWII-era shark repellant by the Navy which not only masks the subject from attack and chemically repels the predator, but provides a psychological aid to a swimmer. The use of shark cages is seen at the 7 minute mark, as well as sound transducers. Shark behavior is studied by divers using noise makers at the 10 minute mark. Shark vision is studied at the 11:50 mark, by Dr. Sam Gruber. Gruber achieved a lot of fame over a long career, replacing irrational fear of sharks with better understanding of them. At the 16:30 mark, San Diego researchers look at sharks from underwater using the Nemo Acrylic bubble and the SiSi catamaran. The Mote Marine Laboratory in Florida is also seen. Mote Marine Laboratory is an independent, not-for-profit marine research organization based on City Island in Sarasota, Florida. Founded in 1955 by Eugenie Clark in Placida, Florida, it was known as the Cape Haze Marine Laboratory until 1967. The laboratory aims to advance the science of the sea, both through its marine and estuarine research labs and through the public Mote Aquarium and its affiliated educational programs. The film ends with tests of a "shark screen" and a "bubble curtain" designed to keep sharks away, with varying success.
