Dive History Flashcards
Mk V designer?
Bureau of construction and repai
Spitcock?
A supplementary relief valve added to left side of helmet allowed to clear the mask with water
How long was MK V in use and what replaced it?
Till 1980, replaces by MK 12, Was used for salvage operations for the USS S-51 and the USS S-4 in the mid-1920s
Caissons?
Dry chambers, a French word meaning big boxes. Were designed to provide ready access from the surface by using an air lock, The pressure inside can be maintained by manner materials could be passed in and out
Caissons disease
Divers would be struck by dizzy spells, breathing difficulties or sharp pains in the joints or abdomen. “Bends”
Paul Bert
Studied the cause of Kasons disease, decompression sickness in 1878, Bert recommended workers gradually decompressed and return slowly to surface
William badder
Navy cross for extreme heroism during salvage USS S-51
Mdv April 1931, M.O.H recipient for heroism during rescue of Squalous survivors
Thomas Eddie
Gm, became diver, part of ISS S-51, S -4, receive navy cross for each operation
M.O.H recipient for rescuing fellow diver during S-4
Frank Criley

Helped in USS S-51, USS Mayflower, squalous
Orson Crandall

James Macdonald
MOH for salvage of USS sailfish, made mdv oct 1934, involved in USS squalous, served with James Macdonald, William badder, John mihalowski, orson Crandall all moh recipients for squalous
John mihalowski

Francis Hamerburg
MOH recipient for salving two trapped divers during rescue efforts in Pearl Harbor, dies feb 17 1945,
Robert Stethum
Seabea Diver,murdered by hezbullah fighters in hijacking of commercial plane June 15, 1985
George f Bond
Bonds saturation theory, Theorized the tissues of the body would eventually become saturated with another gas if expose long enough. Initiated the Genesis project a test theory of saturation.
Genesis project
Tested the theory of saturation diving a series of experiments on humans and animals that prove that saturated divers needed extensions of bottom time which would require no decompression time
Sea lab program
The best known U.S. Navy experiment in sat diving
Sealab I and II
Sealab I constructed in pcb,
- 4 man, 10 days at 192fsw
Sealab II
-3 teams of 10 men, 205fsw, each spend 15 days at depth, astronaut Scott carpenter spent 30 days
Sealab III
First time man had been saturated at 1000fsw, proved work can be done at that depth and can return home without harm,
Aquanot Berry Canon died at 600fsw, convulsed and drowned,
USS F-4
Submarine sink near Honolulu Hawaii 305fsw
- 21 men died
- divers had :10 BT used at at that depth only
- navy dive Manuel and school grew from this salvage
USS S-51
Rammed by passenger liner and sunk in Rhode Island
- 132fsw
- salvage took 10 months
- dive school was reinstated and in following years air deco tables came because of this salvage
USS S-4
Collided with Coast Guard Cutter
- 102fsw, took 22 hours for divers to get on scene
- made contact with Men Alice in sub but couldn’t save them in time
- Lt. CB Momsen developed escape lung
USS squalous (sailfish)
Navy developed rescue chamber, McCannon Erickson rescue chamber was -33 saved out of 50 from 243fsw
- first use of HeO2 in salvage diving
USS Thresher
Nuclear attack sub
Sank in 8,400 fsw, deeper then anything could reach at time
Piping system failure
Deep Submergence Review Group (DSRG) developed
