DeepFlight Challenger
DeepFlight Challenger is a one-person personal submarine deep submergence vehicle with full ocean depth capability. It is an "aero-submarine" which uses hydrodynamic forces to descend, as the sub has positive buoyancy, utilizing DeepFlight technology from Hawkes Ocean Technologies. The submarine is currently owned by Virgin Oceanic. History The submarine was designed by Graham Hawkes and Hawkes Ocean Technologies. It was originally ordered by Steve Fossett for an attempt on the Challenger Deep, to become the first solo dive there.Virgin OceanicSub (accessed 27 March 2012)CNet News Daniel Terdiman, 3 October 2008 (accessed 27 March 2012) Planning for the submarine started in 2000.New York Times"The Challenger’s Deep-Sea Brethren" Andy Isaacson, 27 March 2012 (accessed 27 March 2012) It was put on the ordersheet in 2005, with a depth capability of 37,000 ft.Hawkes Ocean TechnologiesInfosheet DeepFlight Challenger (accessed 27 March 2012) The craft was named "Challenger" af ...

Personal Submarine
A personal submarine is a submarine, usually privately funded and constructed, which is usually primarily intended for recreational use. Some are also used for scientific or military purposes. Other uses include tourism, filming, water sporting, rescuing and spying. Some are as long as with capacity to stay underwater for several weeks (e.g. Migaloo submarine yacht). Those personal submarines which are available for sale cost from US$16,000 to 2+ Billion USD. A wide range of them is available from 1-person to 34+ occupants, some can go just 12 meters underwater and some can even reach to Mariana Trench. Such submarines can be designed from scratch by the builder or built to available plans.

Alameda Naval Air Station
Naval Air Station Alameda (NAS Alameda) was a United States Navy Naval Air Station in Alameda, California, on San Francisco Bay. NAS Alameda had two runways: 13–31 measuring and 07-25 measuring . Two helicopter pads and a control tower were also part of the facilities. History In 1927, wetlands at the west end of Alameda Island on the east shore of San Francisco Bay were filled to form an airport (Alameda Airport) with an east–west runway, three hangars, an administration building, and a yacht harbor. The airport site included the Alameda Terminal of the First transcontinental railroad (California Historical Landmark #440). By 1930, United States Army Air Corps operations referred to the site as Benton Field. Pan American World Airways used the yacht harbor as the California terminal for ''China Clipper'' trans-Pacific flights beginning in 1935. The ''China Clipper'' terminal is designated California Historical Landmark #968. On 1 June 1936, the city of Alameda, Calif ...

Bathyscaphe Trieste
''Trieste'' is a Swiss-designed, Italian-built deep-diving research bathyscaphe which reached a record depth of about in the Challenger Deep of the Mariana Trench near Guam in the Pacific. On 23 January 1960, Jacques Piccard (son of the boat's designer Auguste Piccard) and US Navy Lieutenant Don Walsh achieved the goal of Project Nekton. It was the first crewed vessel to reach the bottom of the Challenger Deep. Design ''Trieste'' consisted of a float chamber filled with gasoline (petrol) for buoyancy, with a separate pressure sphere to hold the crew. This configuration (dubbed a "bathyscaphe" by the Piccards) allowed for a free dive, rather than the previous bathysphere designs in which a sphere was lowered to depth and raised again to the surface by a cable attached to a ship. ''Trieste'' was designed by the Swiss scientist Auguste Piccard and originally built in Italy. His pressure sphere, composed of two sections, was built by Acciaierie Terni. The upper part was manufactu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arctic Ocean
The Arctic Ocean is the smallest and shallowest of the world's five major oceans. It spans an area of approximately and is known as the coldest of all the oceans. The International Hydrographic Organization (IHO) recognizes it as an ocean, although some oceanographers call it the Arctic Mediterranean Sea. It has been described approximately as an estuary of the Atlantic Ocean. It is also seen as the northernmost part of the all-encompassing World Ocean. The Arctic Ocean includes the North Pole region in the middle of the Northern Hemisphere and extends south to about 60°N. The Arctic Ocean is surrounded by Eurasia and North America, and the borders follow topographic features: the Bering Strait on the Pacific side and the Greenland Scotland Ridge on the Atlantic side. It is mostly covered by sea ice throughout the year and almost completely in winter. The Arctic Ocean's surface temperature and salinity vary seasonally as the ice cover melts and freezes; its salinity is t ...

Molloy Deep
The Molloy Deep (also known as the Molloy Hole) is a bathymetric feature in the Fram Strait, within the Greenland Sea east of Greenland and about 160 km west of Svalbard. It is the location of the deepest point in the Arctic Ocean. The Molloy Deep, Molloy Hole, Molloy Fracture Zone, and Molloy Ridge were named after Arthur E. Molloy, a U.S. Navy research scientist who worked in the North Atlantic, North Pacific and Arctic Oceans in the 1950s-1970s. The outer rim of the trench is at a depth of and contains about 600 km2 inside the rim, descending to approximately at its greatest depth. The basin floor measures about 220 km2, and is the deepest point in the Arctic Ocean. The first and only person to have reached the bottom of the Molloy Deep is American explorer Victor Vescovo, as part of his Five Deeps Expedition. Topography The Molloy Deep is a roughly rectangular, seismically active, extensional, sea-floor basin, that lies between the northwestern tip of the Molloy ...

Southern Ocean
The Southern Ocean, also known as the Antarctic Ocean, comprises the southernmost waters of the World Ocean, generally taken to be south of 60° S latitude and encircling Antarctica. With a size of , it is regarded as the second-smallest of the five principal oceanic divisions: smaller than the Pacific, Atlantic, and Indian oceans but larger than the Arctic Ocean. Over the past 30 years, the Southern Ocean has been subject to rapid climate change, which has led to changes in the marine ecosystem. By way of his voyages in the 1770s, James Cook proved that waters encompassed the southern latitudes of the globe. Since then, geographers have disagreed on the Southern Ocean's northern boundary or even existence, considering the waters as various parts of the Pacific, Atlantic, and Indian oceans, instead. However, according to Commodore John Leech of the International Hydrographic Organization (IHO), recent oceanographic research has discovered the importance of Southern ...

South Sandwich Trench
The South Sandwich Trench is a deep volcanic arc, arcuate ocean trench, trench in the South Atlantic Ocean lying to the east of the South Sandwich Islands. It is the deepest oceanic trench, trench of the Southern Atlantic Ocean, and the second deepest of the Atlantic Ocean after the Puerto Rico Trench. Since the trench extends south of the 60th parallel south, it also contains the deepest point in the Southern Ocean. The deepest point in the entire trench is the Meteor Deep, whose location prior to February 2019 was identified as at a depth of . This sounding was made during the German Meteor expedition. The depth is named after the German survey ship Meteor, which first surveyed the area as part of its namesake expedition in 1926. The deepest point below the 60th parallel south, the deepest point in the Southern Ocean, is dubbed by Victor Vescovo as the Factorian Deep, a name that he hopes will become official. This point lies at a depth of , and is the only subzero Hadal zone ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indian Ocean
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or ~19.8% of the water on Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica, depending on the definition in use. Along its core, the Indian Ocean has some large marginal or regional seas such as the Arabian Sea, Laccadive Sea, Bay of Bengal, and Andaman Sea. Etymology The Indian Ocean has been known by its present name since at least 1515 when the Latin form ''Oceanus Orientalis Indicus'' ("Indian Eastern Ocean") is attested, named after Indian subcontinent, India, which projects into it. It was earlier known as the ''Eastern Ocean'', a term that was still in use during the mid-18th century (see map), as opposed to the ''Western Ocean'' (Atlantic Ocean, Atlantic) before the Pacific Ocean, Pacific was surmised. Conversely, Ming treasure voyages, Chinese explorers in the Indian Oce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diamantina Trench
The Diamantina Fracture Zone (DFZ) is an area of the south-eastern Indian Ocean seafloor, consisting of a range of ridges and trenches. It lies to the south of the mideastern Indian Ocean features of the Wharton Basin and Perth Basin, and to the south west of the Naturaliste Plateau. Escarpment Being parallel to the Southeast Indian Ridge, the Diamantina Fracture Zone is not a true fracture zone in the sense used in plate tectonics, but rather an escarpment, separating two oceanic plateaus. Its extension to the west is called the Diamantina Escarpment. This is the southern border of the Broken Ridge Plateau. All these features are mirrored by corresponding topography on the other side of the Southeast Indian Ridge. The Broken Ridge Plateau was formed at the ridge together with the Kerguelen Plateau. Exploration The Diamantina Fracture Zone was first detected by and RV ''Argo'' in 1960. It is named after , which conducted further exploration in 1961. Professor Alan Jamies ...

Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.
