Wreck Diving
Wreck diving is recreational diving where the wreckage of ships, aircraft and other artificial structures are explored. Although most wreck dive sites are at shipwrecks, there is an increasing trend to scuttle retired ships to create artificial reef sites. Diving to crashed aircraft can also be considered wreck diving. The recreation of wreck diving makes no distinction as to how the vessel ended up on the bottom. Some wreck diving involves penetration of the wreckage, making a direct ascent to the surface impossible for a part of the dive. Reasons for diving wrecks A shipwreck may be attractive to divers for several reasons: * it serves as an artificial reef, which creates a habitat for many types of marine life * it often is a large structure with many interesting parts and machinery, which is not normally closely observable on working, floating vessels * it often has an interesting history * it presents new skill challenges for scuba divers to manage the risks associate ...

Shadow Divers
''Shadow Divers: The True Adventure of Two Americans Who Risked Everything to Solve One of the Last Mysteries of World War II'' is a 2004 non-fiction book by Robert Kurson recounting of the discovery of a World War II German U-boat off the coast of New Jersey, United States in 1991, exploration dives, and its eventual identification as ''U-869'' lost on 11 February 1945. Overview In 1991, a group of divers, including John Chatterton, set out on ''Seeker'' to explore an unknown object lying below the surface of the Atlantic Ocean and discover a World War II German U-boat off the coast of New Jersey. Amazed at this discovery, Chatterton and his fellow divers make a pact to keep the U-boat a secret until they can discover its identity and claim credit for its discovery. This is to prevent "wreck-jumping" (wherein another person claims credit and/or removes objects from the wreck). Unfortunately, this pact is broken almost immediately by team members who tell close friends, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intensive Care Unit
220px, Intensive care unit An intensive care unit (ICU), also known as an intensive therapy unit or intensive treatment unit (ITU) or critical care unit (CCU), is a special department of a hospital or health care facility that provides intensive care medicine. Intensive care units cater to patients with severe or life-threatening illnesses and injuries, which require constant care, close supervision from life support equipment and medication in order to ensure normal bodily functions. They are staffed by highly trained physicians, nurses and respiratory therapists who specialize in caring for critically ill patients. ICUs are also distinguished from general hospital wards by a higher staff-to-patient ratio and access to advanced medical resources and equipment that is not routinely available elsewhere. Common conditions that are treated within ICUs include acute respiratory distress syndrome, septic shock, and other life-threatening conditions. Patients may be referred dire ...

Gulf Of Mexico
The Gulf of Mexico ( es, Golfo de México) is an oceanic basin, ocean basin and a marginal sea of the Atlantic Ocean, largely surrounded by the North American continent. It is bounded on the northeast, north and northwest by the Gulf Coast of the United States; on the southwest and south by the Mexico, Mexican States of Mexico, states of Tamaulipas, Veracruz, Tabasco, Campeche, Yucatan, and Quintana Roo; and on the southeast by Cuba. The Southern United States, Southern U.S. states of Texas, Louisiana, Mississippi, Alabama, and Florida, which border the Gulf on the north, are often referred to as the "Third Coast" of the United States (in addition to its Atlantic and Pacific Ocean, Pacific coasts). The Gulf of Mexico took shape approximately 300 million years ago as a result of plate tectonics.Huerta, A.D., and D.L.

Brigantine
A brigantine is a two-masted sailing vessel with a fully square-rigged foremast and at least two sails on the main mast: a square topsail and a gaff sail mainsail (behind the mast). The main mast is the second and taller of the two masts. Older usages are looser; in addition to the rigorous definition above (attested from 1695), the ''Oxford English Dictionary'' has about 1525 definitions of "a small vessel equipped both for sailing and rowing, swifter and more easily manœuvred than larger ships" and "(loosely) various kinds of foreign sailing and rowing vessels, as the galleon, galliot, etc." Modern American definitions include vessels without the square sails on the main mast. Mediterranean brigantines In the Mediterranean Basin during the 13th century, a brigantine referred to a sail- and oar-driven war vessel. It was lateen rigged on two masts and had between eight and twelve oars on each side. Its speed, maneuverability, and ease of handling made it a favourite of Mediter ...

USS Wilkes-Barre (CL-103)
USS ''Wilkes-Barre'' was a light cruiser of the United States Navy, which were built during World War II. The class was designed as a development of the earlier s, the size of which had been limited by the First London Naval Treaty. The start of the war led to the dissolution of the treaty system, but the dramatic need for new vessels precluded a new design, so the ''Cleveland''s used the same hull as their predecessors, but were significantly heavier. The ''Cleveland''s carried a main battery of twelve guns in four three-gun turrets, along with a secondary armament of twelve dual-purpose guns. They had a top speed of . Design The ''Cleveland''-class light cruisers traced their origin to design work done in the late 1930s; at the time, light cruiser displacement was limited to by the Second London Naval Treaty. Following the start of World War II in September 1939, Britain announced it would suspend the treaty for the duration of the conflict, a decision th ...

SS Andrea Doria
SS ''Andrea Doria'' , was an ocean liner for the Italian Line (Società di navigazione Italia) home-ported in Genoa, Italy, known for its sinking in 1956, where of the 1,706 passengers and crew, 1,660 were rescued, while 46 passengers and crew died. Named after the 16th-century Genoese admiral Andrea Doria, the ship had a gross register tonnage of 29,100 and a capacity of about 1,200 passengers and 500 crew. Of all Italy's ships at the time, ''Andrea Doria'' was the largest, fastest and supposedly safest. Launched on 16 June 1951, the ship began her maiden voyage on 14 January 1953. On 25 July 1956, while ''Andrea Doria'' was approaching the coast of Nantucket, Massachusetts, United States, bound for New York City, the eastbound of the Swedish American Line collided with her. Struck in the side, the top-heavy ''Andrea Doria'' immediately started to list severely to starboard, which left half of her lifeboats unusable. The consequent shortage of lifeboats could have result ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USS Monitor
USS ''Monitor'' was an ironclad warship built for the Union Navy during the American Civil War and completed in early 1862, the first such ship commissioned by the Navy. ''Monitor'' played a central role in the Battle of Hampton Roads on 9 March under the command of Lieutenant John L. Worden, where she fought the casemate ironclad (built on the hull of the scuttled steam frigate ) to a stalemate. The design of the ship was distinguished by its revolving turret, which was designed by American inventor Theodore Timby; it was quickly duplicated and established the monitor class and type of armored warship built for the American Navy over the next several decades. The remainder of the ship was designed by Swedish-born engineer and inventor John Ericsson, and built in only 101 days in Brooklyn, New York on the East River beginning in late 1861. ''Monitor'' presented a new concept in ship design and employed a variety of new inventions and innovations in ship building that caught ...
