Some of the mission areas of the Navy diver include: marine salvage, harbor clearance, underwater ship husbandry and repair, submarine rescue, saturation diving, experimental diving, underwater construction and welding, as well as serving as technical experts to the Navy SEALs, Marine Corps, and Navy EOD diving commands. The U.S. Navy is the lead agency in military diving technology and training within the U.S. Department of Defense.

Pacific Ocean Theater Of World War II
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Marine Salvage
Marine salvage is the process of recovering a ship and its cargo after a shipwreck or other maritime casualty. Salvage may encompass towing, re-floating a vessel, or effecting repairs to a ship. Today, protecting the coastal environment from spillage of oil or other contaminants is a high priority. Before the invention of radio, salvage services would be given to a stricken vessel by any ship that happened to be passing by. Nowadays, most salvage is carried out by specialist salvage firms with dedicated crew and equipment. The legal significance of salvage is that a successful salvor is entitled to a reward, which is a proportion of the total value of the ship and its cargo. The amount of the award is determined subsequently at a "hearing on the merits" by a maritime court in accordance with Articles 13 and 14 of the International Salvage Convention of 1989. The common law concept of salvage was established by the English Admiralty Court, and is defined as "a voluntary succe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Attack On Pearl Harbor
The attack on Pearl HarborAlso known as the Battle of Pearl Harbor was a surprise military strike by the Imperial Japanese Navy Air Service upon the United States against the naval base at Pearl Harbor in Honolulu, Territory of Hawaii, just before 8:00a.m. (local time) on Sunday, December 7, 1941. The United States was a neutral country at the time; the attack led to its formal entry into World War II the next day. The Japanese military leadership referred to the attack as the Hawaii Operation and Operation AI, and as Operation Z during its planning. Japan intended the attack as a preventive action. Its aim was to prevent the United States Pacific Fleet from interfering with its planned military actions in Southeast Asia against overseas territories of the United Kingdom, the Netherlands, and those of the United States. Over the course of seven hours there were coordinated Japanese attacks on the US-held Philippines, Guam, and Wake Island and on the British Empire ...

Medal Of Honor
The Medal of Honor (MOH) is the United States Armed Forces' highest military decoration and is awarded to recognize American soldiers, sailors, marines, airmen, guardians and coast guardsmen who have distinguished themselves by acts of valor. The medal is normally awarded by the president of the United States, but as it is presented "in the name of the United States Congress", it is sometimes erroneously referred to as the "Congressional Medal of Honor". There are three distinct variants of the medal: one for the Department of the Army, awarded to soldiers, one for the Department of the Navy, awarded to sailors, marines, and coast guardsmen, and one for the Department of the Air Force, awarded to airmen and guardians. The Medal of Honor was introduced for the Department of the Navy in 1861, soon followed by the Department of the Army's version in 1862. The Department of the Air Force used the Department of the Army's version until they received their own distinctive version i ...

Naval Station Newport
The Naval Station Newport (NAVSTA Newport) is a United States Navy base located in the city of Newport and the town of Middletown, Rhode Island. Naval Station Newport is home to the Naval War College and the Naval Justice School. It once was the homeport for Cruiser Destroyer Force Atlantic (COMCRUDESLANT), which relocated to Naval Station Norfolk in the early 1970s. In 1989 the base was added to the National Priorities List, after contamination had been discovered years earlier. Newport now maintains inactive ships at its pier facilities, along with the United States Coast Guard. In BRAC 2005 (Base Realignment and Closure), NAVSTA Newport gained over five hundred billets, in addition to receiving, again, the Officer Candidate School (OCS), the Naval Supply Corps School (in 2011''See:'' Navy Supply Corps (United States)#Navy Supply Corps School.), and several other activities, to include a few Army Reserve units. Geography As of 2022 Naval Station Newport, encompasses 1,063 acr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Haldane's Decompression Model
Haldane's decompression model is a mathematical model for Decompression (diving), decompression to sea level atmospheric pressure of divers breathing compressed air at ambient pressure that was proposed in 1908 by the Scottish physiologist, John Scott Haldane (2 May 1860 – 14/15 March 1936), who was also famous for intrepid self-experimentation. Haldane prepared the first recognized Decompression theory#John Scott Haldane, decompression table for the British Admiralty in 1908 based on extensive experiments on goats and other animals using a clinical endpoint of symptomatic decompression sickness. Haldane observed that goats, saturated to depths of of sea water, did not develop decompression sickness (DCS) if subsequent Decompression (diving), decompression was limited to half the ambient pressure. Haldane constructed schedules which limited the critical supersaturation ratio to "2", in five hypothetical body tissue compartments characterized by their halftime. Halftime is ...
