Bathysphere Entrance Port




Bathysphere Entrance Port





The Bathysphere (Greek words ????? (bathos), "depth" and ?????? (sphaira), "sphere") is a spherical deep-sea submersible which was unpowered and lowered into the ocean on a cable, and was used to conduct a series of dives off the coast of Bermuda from 1930 to 1934. The Bathysphere was designed in 1928 and 1929 by the American Engineer Otis Barton, to be used by the naturalist William Beebe for studying undersea wildlife. Beebe and Barton conducted dives in the Bathysphere together, marking the first time that a marine biologist observed deep-sea animals in their native environment. Their dives set several consecutive world records for the deepest dive ever performed by a human. The record set by the deepest of these, to a depth of 3,028 feet on August 15, 1934, lasted until it was broken by Barton in 1949.

In 1928, the American naturalist William Beebe was given permission by the British government to establish a research station on Nonsuch Island, Bermuda. Using this station, Beebe planned to conduct an in-depth study of the animals inhabiting an eight-mile-square area of ocean, from a depth of two miles to the surface. Although his initial plan called for him to conduct this study by means of helmet diving and dredging, Beebe soon realized that these methods were inadequate for gaining a detailed understanding of deep-sea animals, and began making plans to invent a way to observe them in their native habitat.

As of the late 1920s, the deepest humans could safely descend in diving helmets was 100 feet, since beyond that point the pressure becomes too great. Submarines of the time had descended to a maximum of 383 feet, but had no windows, making them useless for Beebe's goal of observing deep-sea animals. The deepest in the ocean that any human had descended at this point was 525 feet wearing an armored suit, but these suits also made movement and observation extremely difficult. What Beebe hoped to create was a deep-sea vessel which both could descend to a much greater depth than any human had descended thus far, and also would enable him to clearly observe and document the deep ocean's wildlife.

Beebe's initial design called for a cylindrical vessel, and articles describing his plans were published in The New York Times. These articles caught the attention of the engineer Otis Barton, who had his own ambition to become a deep-sea explorer. Barton was certain that a cylinder would not be strong enough to withstand the pressure of the depths to which Beebe was planning to descend, and sent Beebe several letters proposing an alternative design to him. So many unqualified opportunists were attempting to join Beebe in his efforts that Beebe tended to ignore most of his mail, and Barton's first efforts to contact him were fruitless. A mutual friend of Barton's and Beebe's eventually arranged a meeting between the two, enabling Barton to present his design to Beebe in person. Beebe approved of Barton's design, and the two of them made a deal: Barton would pay for the vessel and all of the other equipment to go with it, while Beebe would pay for other expenses such as chartering a ship to raise and lower it, and as the owner of the vessel Barton would accompany Beebe on his dives in it.

Barton's design called for a spherical vessel, as a sphere is the best possible shape for resisting high pressure. The sphere had openings for three 3-inch-thick (76 mm) windows made of fused quartz, the strongest transparent material then available, as well a 400-pound entrance hatch which was to be bolted down before a descent. Initially only two of the windows were mounted on the sphere, and a steel plug was mounted in place of the third window. Oxygen was supplied from high-pressure cylinders carried inside the sphere, while pans of soda lime and calcium chloride were mounted inside the sphere's walls to absorb exhaled CO2 and moisture. Air was to be circulated past these trays by the Bathysphere's occupants using palm-leaf fans.

The casting of the steel sphere was handled by Watson Stillman Hydraulic Machinery Company in Roselle, New Jersey, and the cord to raise and lower the sphere was provided by John A. Roebling's Sons Company. General Electric provided a lamp which would be mounted just inside one of the windows to illuminate animals outside the sphere, and Bell Laboratories provided a telephone system by which divers inside the sphere could communicate with the surface. The cables for the telephone and to provide electricity for the lamp were sealed inside a rubber hose, which entered the body of the Bathysphere through a stuffing box.

After the initial version of the sphere had been cast in June 1929, it was discovered that it was too heavy to be lifted by the winch which would be used to lower it into the ocean, requiring Barton to have the sphere melted and re-cast. The final, lighter design consisted of a hollow sphere of 1-inch-thick (25 mm) cast steel which was 4.75 ft (1.5 m) in diamete











Sardine Fishery Diving Helmet




Sardine Fishery Diving Helmet





On an escapade, I noticed this old, banged-up diving head gear at San Carlos Beach Park next to the Bay of Monterey, California. Divers with such helmets maintained underwater pipelines and equipment that were used to suck up sardines from fishing vessels.

Actually, this one is a replica of an old helmet used for surface supplied diving; it stands as a memorial to divers who often risked their lives working underwater for the big canning companies. It was manufactured by Morse Diving Equipment in Boston.

21st Century U.S. Army Field Manuals: Military Diving, FM 20-11, Volume 2, Air Diving Operations, Scuba, Surface-Supplied, Air Decompression, Ice and Cold Operations (Ringbound)






This ringbound book provides a reproduction of the U.S. Army Field Manual, Military Diving, FM 20-11, Volume 2, Air Diving, Operations, Scuba, Surface-Supplied, Air Decompression, Ice and Cold Operations. The U.S. Navy is a leader in the development of modern diving and underwater operations. The general requirements of national defense and the specific requirements of underwater reconnaissance, demolition, ordnance disposal, construction, ship maintenance, search, rescue and salvage operations repeatedly give impetus to training and development. Navy diving is no longer limited to tactical combat operations, wartime salvage, and submarine sinkings. Fleet diving has become increasingly important and diversified since World War II. A major part of the diving mission is inspecting and repairing naval vessels to minimize downtime and the need for dry-docking. Other aspects of fleet diving include recovering practice and research torpedoes, installing and repairing underwater electronic arrays, underwater construction, and locating and recovering downed aircraft. The origins of diving are firmly rooted in man's need and desire to engage in maritime commerce, to conduct salvage and military operations, and to expand the frontiers of knowledge through exploration, research, and development. Diving, as a profession, can be traced back more than 5,000 years. Early divers confined their efforts to waters less than 100 feet deep, performing salvage work and harvesting food, sponges, coral, and mother-of-pearl. Contents include: Underwater Ship Husbandry (UWSH), Salvage/Object Recovery, Operational Tasks, Security Swims, Explosive Ordnance Disposal, Underwater Construction, Demolition, Collect and Analyze Data, Data Required for All Diving Operations, Identify Environmental and Operational Hazards, Temperature, Contaminated Water, Thermal Pollution, Chemical, Biological, Altitude Diving, Underwater Obstacles, Electrical Shock Hazards, Explosions, Sonar, Nuclear Radiation, Marine Life, Vessel and Small Boat Traffic, Territorial Waters, Diving Technique, Equipment and Supplies, Manning Levels, Buddy Diver, OSHA Requirements for Navy Civilian Diving, Brief the Diving Team, Scuba Air Diving Operations, Open-Circuit Scuba, Minimum Equipment, Optional Equipment, Predive Procedures, Water Entry and Descent, Underwater Procedures, Surface-Supplied Air Diving Operations, Mark 21 and Mark 20, Portable Surface-Supplied Diving Systems, Underwater Procedures, Air Decompression, Repetitive Dives, Nitrox Driving Procedures, Emergency Procedures, Lost Diver, Searching for A Lost Diver, Hypothermia. Our news and educational titles are privately compiled collections of official public domain U.S. government files and documents - they are not produced by the federal government.
