• A Navy Diver can perform underwater ship repair, salvage, and construction, using either SCUBA equipment or a surface-supplied-air diving system.
• Gilliam performed a deep air dive on February 14, 1990 at a site named " Mary's Place " in Roat醤 to.
• A PFO conveniently explains neurological accidents after recreational air diving without any procedure violation, but it does not explain vestibular hits in deep diving.
• This resulted in the RN adding the time spent at 10 feet to the 20-foot stop for air dives and surfacing directly from 20 feet.
• While dive industry safety standards specify the need for standby safety equipment, specific standby equipment is not required by regulation for surface-supplied air dives to depths less than 130 feet.
• For shallow water surface supply air diving, the diver's umbilical is typically a 3-part umbilical comprising a gas hose, pneumofathometer ( " pneumo " ) hose, and diver communications cable, which usually also serves as a lifeline strength member.
• Protracted heavy rains will likely be focused farther away from the Gulf Coast, occurring where the leading edge of cold air diving south over the Plains meets the leading edge of tropical air surging north from the Gulf of Mexico.
• They also remain relatively common in shallow-water air diving, where gas consumption is of little concern, and in nuclear diving because they must be disposed of after some period of use due to irradiation; free-flow helmets are significantly less expensive to purchase and maintain than demand types.
• Divers trained and experienced in deep air diving report fewer problems with narcosis than those trained and experienced in mixed gas diving trimix / heliox, although scientific evidence does not show that a diver can train to overcome any measure of narcosis at a given depth, or become tolerant of it.
• The scientific diving community has never specified a 130-foot limit in its protocols and has never experienced any accidents or injuries during air dives between 130 feet and the deepest air dives that the scientific diving community permits, 190 feet, where the U . S . Navy Standard Air Tables shifts to the Exceptional Exposure Tables.
