Pisces V
''Pisces V'' is a type of crewed submersible ocean exploration device, powered by battery, and capable of operating to depths of , a depth that is optimum for use in the sea waters around the Hawaiian Islands. It is used by scientists to explore the deep sea around the underwater banks in the main Hawaiian Islands, as well as the underwater features and seamounts in the Northwestern Hawaiian Islands, specifically around Kamaʻehuakanaloa Seamount (formerly Loihi). In 1973, ''Pisces V'' took part in the rescue of Roger Mallinson and Roger Chapman, who were trapped on the seabed in ''Pisces V''s sister submersible '' Pisces III''. In August 2002, ''Pisces V'' and her sister ''Pisces IV'' discovered a World War II Japanese midget submarine outside of Pearl Harbor which had been sunk by the destroyer in the first American shots fired in World War II. In 2011, marine scientists from HURL celebrated the 1,000 dives of ''Pisces V'' and ''Pisces IV''. Uses The advantage of having ...

Submersible
A submersible is an underwater vehicle which needs to be transported and supported by a larger ship, watercraft or dock, platform. This distinguishes submersibles from submarines, which are self-supporting and capable of prolonged independent operation at sea. There are many types of submersibles, including both human-occupied vehicles (HOVs) and uncrewed craft, variously known as remotely operated vehicles (ROVs) or unmanned underwater vehicles (UUVs). Submersibles have many uses including oceanography, underwater archaeology, ocean exploration, tourism, underwater work, equipment maintenance and underwater search and recovery, recovery and underwater videography. History The first recorded self-propelled underwater vessel was a small oar-powered submarine conceived by William Bourne (mathematician), William Bourne (c. 1535 – 1582) and designed and built by Dutch inventor Cornelis Drebbel in 1620, with two more improved versions built in the following four years.Konstam (201 ...

Depth Charge

(It differs from a submersible, which has more limited underwater capability.) The term "submarine" is also sometimes used historically or infor ...s by detonating in the water near the target and subjecting it to a destructive shock factor, hydraulic shock. Most depth charges use high explosives with a fuze set to detonate the charge, typically at a specific depth from the surface. Depth charges can be dropped by ships (typically fast, agile surface combatants such as destroyers or frigates), patrol aircraft and helicopters. Depth charges were developed during World War I, and were one of the first viable methods of attacking a submarine underwater. They were widely used in World War I and World War II, and remained part of the anti-submarine arsenals of many navies during the Cold War, duri ...

Submarines Of The United States
A submarine (often shortened to sub) is a watercraft capable of independent operation underwater. (It differs from a submersible, which has more limited underwater capability.) The term "submarine" is also sometimes used historically or informally to refer to remotely operated vehicles and robots, or to medium-sized or smaller vessels (such as the midget submarine and the wet sub). Submarines are referred to as ''boats'' rather than ''ships'' regardless of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and submarines were adopted by several navies. They were first used widely during World War I (1914–1918), and are now used in many navies, large and small. Their military uses include: attacking enemy surface ships (merchant and military) or other submarines; aircraft carrier protection; blockade running; nuclear deterrence; stealth operations in denied areas when gathering intelligence and doing reconn ...

Ships Built In North Vancouver
A ship is a large vessel that travels the world's oceans and other navigable waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is square-rigged. The earliest historical evidence of boats is found in Egypt during the 4th millennium BCE. In 2024, ships had a global cargo capacity of 2.4 billion tons, with the three largest classes being ships carrying dry bulk (43%), oil tankers (28%) and container ships (14%).

Bamboo Coral
Bamboo coral, family Keratoisididae (formerly Isididae) is a family of coral of the phylum Cnidaria. It is a commonly recognized inhabitant of the deep sea, due to the clearly articulated skeletons of the species. Deep water coral species such as this are especially affected by the practice of bottom trawling. These organisms may be an important environmental indicator in the study of long term climate change, as some specimens of bamboo coral have been discovered that are 4,000 years old. Bamboo corals were previously defined to be the family Isididae, based on their articulated skeletons with proteinaceous joints, but this family was shown to be paraphyletic after it was found in 2021 that this had evolved at least five separate times. As of 2023, the taxonomy of bamboo corals is being actively revised. Description Relatively little is known about bamboo coral. The skeletons of bamboo coral are made up of calcium carbonate in the form of tree-like branches alternating with j ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mokupapapa Discovery Center
The S. Hata Building is a historic structure in Hilo, Hawaii built by Japanese businessman Hata Sadanosuke (1868 - ?) in 1912. It now contains specialty shops, professional offices, and a Cafe Pesto restaurant. Hata family Hata Sadanosuke was born in Hiroshima, Japan in 1868 and immigrated to Honolulu, Hawaii in 1891. In 1893, Mr. Hata worked as an agent for Odo Shoten in Honolulu ("shoten" means "store" in Japanese), responsible for taking orders from large sugarcane plantations on the Hāmākua Coast which employed many Japanese immigrant workers. This gave him the inspiration to start his own business at Hilo on the Big Island on January 3, 1896 called S. Hata Shoten, Limited. He sold Japanese silks, kimono, as well as eastern souvenirs and provisions. Business was slow in the first years, so he hired out his horse and hackney carriage as a taxicab for visitors. After the annexation by the United States to become the Territory of Hawaii in 1898, the plantations flourish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
