Pisces IV
''Pisces IV'' is a three-person, battery-powered deep-submergence vehicle (or DSV), with a maximum operating depth of . The craft was built by Hyco International Hydrodynamics in Vancouver, and is currently owned by the Hawaii Undersea Research Laboratory arm of the National Oceanic and Atmospheric Administration. It and its sister, ''Pisces V'', are Pisces class submersibles used by the NOAA for oceanic exploration. ''Pisces IV'' was constructed in 1973 and immediately placed in the service of the Department of Fisheries and Oceans of Canada. The DSV was used by the Institute of Ocean Sciences and operated at different times in the Atlantic, Arctic, and Pacific oceans. After over 1886 dives, budget cuts forced the cancellation of support for the project. ''Pisces IV'' has since been replaced in that role by ''ROPOS''. More recently, after transfer to the US, ''Pisces IV'' was certified for use by the American Bureau of Shipping in 2000, and underwent modernization and upgrading ...

Flag Of Canada
The national flag of Canada (french: le Drapeau national du Canada), often simply referred to as the Canadian flag or, unofficially, as the Maple Leaf or ' (; ), consists of a red field with a white square at its centre in the ratio of , in which is featured a stylized, red, 11-pointed maple leaf charged in the centre. It is the first flag to have been adopted by both houses of Parliament and officially proclaimed by the Canadian monarch as the country's official national flag. The flag has become the predominant and most recognizable national symbol of Canada. In 1964, Prime Minister Lester B. Pearson formed a committee to resolve the ongoing issue of the lack of an official Canadian flag, sparking a serious debate about a flag change to replace the Union Flag. Out of three choices, the maple leaf design by George Stanley, based on the flag of the Royal Military College of Canada, was selected. The flag made its first official appearance on February 15, 1965; the date i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ROPOS
ROPOS ("Remotely Operated Platform for Ocean Science") is an ROV used primarily for scientific research. It was originally built in Vancouver by International Submarine Engineering and purchased by the Canadian federal government. The same government program also operated the '' Pisces IV'' crewed submersible, now in Hawaii being run by the Hawai'i Undersea Research Laboratory (HURL) who found the long-lost two-man Japanese sub which heralded the attack on Pearl Harbor. The funding for the Canadian submersible program eventually dried up, but by that time the user group had been established and long term experiments put in place on the sea floor. The Canadian Scientific Submersible Facility (CSSF) was formed and leased ROPOS from the government for several years before finally purchasing the ROV a few years ago. In 2005 the vehicle was extensively rebuilt and now boasts a thru-frame lift capability (see below). The ROV is controlled and powered from a surface vessel. Electrical ...

Submarines Of Canada
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 spe ...

Hydrothermal Vent
A hydrothermal vent is a fissure on the seabed from which geothermally heated water discharges. They are commonly found near volcanically active places, areas where tectonic plates are moving apart at mid-ocean ridges, ocean basins, and hotspots. Hydrothermal deposits are rocks and mineral ore deposits formed by the action of hydrothermal vents. Hydrothermal vents exist because the earth is both geologically active and has large amounts of water on its surface and within its crust. Under the sea, they may form features called black smokers or white smokers. Relative to the majority of the deep sea, the areas around hydrothermal vents are biologically more productive, often hosting complex communities fueled by the chemicals dissolved in the vent fluids. Chemosynthetic bacteria and Archaea form the base of the food chain, supporting diverse organisms, including giant tube worms, clams, limpets and shrimp. Active hydrothermal vents are thought to exist on Jupiter's moon Europa an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Conning Tower
A conning tower is a raised platform on a ship or submarine, often armored, from which an officer in charge can conn the vessel, controlling movements of the ship by giving orders to those responsible for the ship's engine, rudder, lines, and ground tackle. It is usually located as high on the ship as practical, to give the conning team good visibility of the entirety of the ship, ocean conditions, and other vessels. The naval term "conn" may derive from the Middle English ''conne'' (study, become acquainted with) or French ''conduire'' from Latin ''conducere'' (conduct). Surface ships On surface ships, the conning tower was a feature of all battleships and armored cruisers from about 1860 to the early years of World War II. Located at the front end of the superstructure, the conning tower was a heavily armored cylinder, with tiny slit windows on three sides providing a reasonable field of view. Designed to shield just enough personnel and devices for navigation during battle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USS Ward (DD-139)
USS ''Ward'' was laid down as a (designated DD-139) in the United States Navy during World War I, later converted to a high speed transport (designated APD-16) in World War II. She was responsible for the first American-caused casualties in the Pacific in World War II when she engaged and sank a Japanese midget submarine before Japanese aircraft arrived in the attack on Pearl Harbor, killing both crewmen on board. Design and construction ''Ward'' was named in honor of Commander James Harmon Ward, USN, (1806–1861), the first U.S. Navy officer to be killed in action during the American Civil War. ''Ward'' was built at the Mare Island Navy Yard, California in a record of 17½ days. Under the pressure of urgent World War I needs for destroyers, her construction was pushed rapidly from keel laying on 15 May 1918 to launching on 1 June and commissioning on 24 July 1918. Service history ''Ward'' transferred to the Atlantic late in the year and helped support the trans-Atlantic ... [...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 ...

Pearl Harbor
Pearl Harbor is an American lagoon harbor on the island of Oahu, Hawaii, west of Honolulu. It was often visited by the Naval fleet of the United States, before it was acquired from the Hawaiian Kingdom by the U.S. with the signing of the Reciprocity Treaty of 1875. Much of the harbor and surrounding lands are now a United States Navy deep-water naval base. It is also the headquarters of the United States Pacific Fleet. The U.S. government first obtained exclusive use of the inlet and the right to maintain a repair and coaling station for ships here in 1887. The surprise attack by the Imperial Japanese Navy on December 7, 1941, led the United States to declare war on the Empire of Japan, making the attack on Pearl Harbor the immediate cause of the United States' entry into World War II. History Pearl Harbor was originally an extensive shallow embayment called ''Wai Momi'' (meaning, “Waters of Pearl”) or ''Puuloa'' (meaning, “long hill”) by the Hawaiians. Puuloa was r ...
