Sub Marine Explorer
''Sub Marine Explorer'' is a submersible built between 1863 and 1866 by Julius H. Kroehl and Ariel Patterson in Brooklyn, New York for the Pacific Pearl Company. It was hand powered and had an interconnected system of a high-pressure air chamber or compartment, a pressurized working chamber for the crew, and water ballast tanks. Problems with decompression sickness and overfishing of the pearl beds led to the abandonment of ''Sub Marine Explorer'' in Panama in 1869 despite publicized plans to shift the craft to the pearl beds of Baja California. Construction ''Sub Marine Explorer'' had an external high air pressure chamber which was filled with compressed air at a pressure of up to by a steam pump mounted on an external support vessel. Water ballast tanks were flooded to make the vessel submerge. Pressurized air was then released into the vessel to build up enough pressure so it would be possible to open two hatches on the underside, while keeping water out. This meant th ...

Pearl Islands
The Pearl Islands (Spanish: Archipiélago de las Perlas or Islas de las Perlas) is a group of 200 or more islands and islets (many tiny and uninhabited) lying about off the Pacific coast of Panama in the Gulf of Panama. Islands The most notable island is Contadora Island (or Isla Contadora in Spanish), known for its resorts. Contadora was said to be used by the Spanish conquistadors as a stop for taking inventory of booty prior to returning to Spain, hence the name (''contador'' means counter or bookkeeper in Spanish). Contadora is a resort island, with many homes owned by wealthy Panamanians. There are a large hotel and other cabins available. Most of the resort workers live on nearby Isla Saboga. In 1979, the Shah of Iran briefly took exile on Isla Contadora. Domestic airline Air Panama runs at least daily flights between Panama City and Contadora and Isla San José. The largest island, at , is Isla del Rey ("Island of the King"), its name probably referring to Christ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
19th-century Submarines Of The United States
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the large S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Submarines
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, blockade running, nuclear deterrence, reconnaissance, conventional land attack (for example, using a cruise missile), and covert insertion of ...

Shipwrecks In The Pacific Ocean
A shipwreck is the wreckage of a ship that is located either beached on land or sunken to the bottom of a body of water. Shipwrecking may be intentional or unintentional. Angela Croome reported in January 1999 that there were approximately three million shipwrecks worldwide (an estimate rapidly endorsed by UNESCO and other organizations). When a ship's crew has died or abandoned the ship, and the ship has remained adrift but unsunk, they are instead referred to as ghost ships. Types Historic wrecks are attractive to maritime archaeologists because they preserve historical information: for example, studying the wreck of revealed information about seafaring, warfare, and life in the 16th century. Military wrecks, caused by a skirmish at sea, are studied to find details about the historic event; they reveal much about the battle that occurred. Discoveries of treasure ships, often from the period of European colonisation, which sank in remote locations leaving few livin ...

Alligator (submarine)
USS ''Alligator'', the fourth United States Navy ship of that name, is the first known U.S. Navy submarine, and was active during the American Civil War (the first American submarine was during the Revolutionary War, and was operated by the Continental Army, vice Navy, in 1776 against British vessels in New York harbor). During the Civil War the Confederate States Navy would also build their own submarine, . Construction In the autumn of 1861, the Union Navy asked the firm of Neafie & Levy to construct a small submersible ship designed by the French engineer Brutus de Villeroi, who also acted as a supervisor during the first phase of the construction (de Villeroi had designed and built submarines in France and one after immigrating to the United States). The boat was about long, with a beam of and height of . "It was made of iron, with the upper part pierced for small circular plates of glass, for light, and in it were several water tight compartments". She was design ...

Historic American Engineering Record
Heritage Documentation Programs (HDP) is a division of the U.S. National Park Service (NPS) responsible for administering the Historic American Buildings Survey (HABS), Historic American Engineering Record (HAER), and Historic American Landscapes Survey (HALS). These programs were established to document historic places in the United States. Records consist of measured drawings, archival photographs, and written reports, and are archived in the Prints and Photographs Division of the Library of Congress. Historic American Buildings Survey In 1933, NPS established the Historic American Buildings Survey following a proposal by Charles E. Peterson, a young landscape architect in the agency. It was founded as a constructive make-work program for architects, draftsmen and photographers left jobless by the Great Depression. It was supported through the Historic Sites Act of 1935. Guided by field instructions from Washington, D.C., the first HABS recorders were tasked with docume ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
