Scott And Seringapatam Reefs
Scott and Seringapatam Reefs is a group of atoll-like reefs in the Timor Sea more than northwest of Cape Leveque, Western Australia, on the edge of the continental shelf. There are three or four separate reef structures, depending on whether Scott Reef Central is counted separately. The group is just one of a number of reef formations off the northwest coast of Australia and belongs to Western Australia. Further to the northeast are Ashmore and Cartier Islands, and to the southwest are the Rowley Shoals. Location and Description Each of the reefs rises steeply from the seabed below. Much of the reef area dries at low tide, but besides Sandy Islet of Scott Reef South, there are only a few rocks and sandbanks above the high water mark. *Scott Reef South (also Horseshoe Reef or South Reef) is a large crescent-shaped formation that has a rare and unusual double reef crest. Its lagoon, has depths of over throughout the greater portion. The reef with its lagoon covers an area ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
STS-80
STS-80 was a Space Shuttle mission flown by Space Shuttle Columbia, Space Shuttle ''Columbia''. The launch was originally scheduled for 31 October 1996, but was delayed to 19 November for several reasons. Likewise, the landing, which was originally scheduled for 5 December, was pushed back to 7 December after bad weather prevented landing for two days. It was the longest Shuttle mission ever flown at 17 days, 15 hours, and 53 minutes. Although two spacewalks were planned for the mission, they were both canceled after problems with the airlock hatch prevented astronauts Tom Jones and Tammy Jernigan from exiting the orbiter. Crew Crew seating arrangements *During landing, Musgrave remained on the flight deck in order to film the spacecraft's reentry through the overhead windows. Mission highlights * The mission deployed two satellites and successfully recovered them after they had performed their tasks. * Orbiting and Retrievable Far and Extreme Ultraviolet Spectrometer-Shu ...

Rowley Shoals
The Rowley Shoals is a group of three atoll-like coral reefs south of the Timor Sea, about west of Broome on the northwestern Australian coast, centered on , on the edge of one of the widest continental shelves in the world. Each atoll covers an area of around within the rim of the reef, including the lagoons, while the land areas are negligible. They belong to Western Australia. They all rise steeply from the surrounding ocean floor. To the northeast lie the Scott and Seringapatam Reefs which are located on the same undersea platform. Naming and history The Rowley Shoals were so named by Captain Phillip Parker King in 1818 in honour of Captain Rowley who first sighted the ''Imperieuse Reef'' in 1800. It is believed that the Rowley Shoals reefs have been visited by fishermen from Indonesia, from at least the mid-18th century. The fishermen were also collecting or hunting for Trepang (holothurians or sea cucumbers), turtle shell, trochus shell and shark fin. These early vi ...

Islands Of Western Australia
An island (or isle) is an isolated piece of habitat that is surrounded by a dramatically different habitat, such as water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. Sedimentary islands in the Ganges delta are called chars. A grouping of geographically or geologically related islands, such as the Philippines, is referred to as an archipelago. There are two main types of islands in the sea: continental and oceanic. There are also artificial islands, which are man-made. Etymology The word ''island'' derives from Middle English ''iland'', from Old English ''igland'' (from ''ig'' or ''ieg'', similarly meaning 'island' when used independently, and -land carrying its contemporary meaning; cf. Dutch ''eiland'' ("island"), German ''Eiland'' ("small island")). However, the spelling of the word ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coral Bleaching
Coral bleaching is the process when corals become white due to various stressors, such as changes in temperature, light, or nutrients. Bleaching occurs when coral polyps expel the zooxanthellae (dinoflagellates that are commonly referred to as algae) that live inside their tissue, causing the coral to turn white. The zooxanthellae are photosynthetic, and as the water temperature rises, they begin to produce reactive oxygen species. This is toxic to the coral, so the coral expels the zooxanthellae. Since the zooxanthellae produce the majority of coral colouration, the coral tissue becomes transparent, revealing the coral skeleton made of calcium carbonate. Most bleached corals appear bright white, but some are blue, yellow, or pink due to pigment proteins in the coral. The leading cause of coral bleaching is rising ocean temperature due to climate change. A temperature about 1 °C (or 2 °F) above average can cause bleaching. According to the United Nations Environment Pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Browse LNG
The Browse LNG was a liquefied natural gas plant project proposed for construction at James Price Point, north of Broome on the Dampier Peninsula, Western Australia. It was considered by a joint venture including Woodside Petroleum, Shell, BP, Japan Australia LNG and BHP Billiton. It would have processed natural gas extracted from the Browse Basin. Liquefied natural gas would then be shipped from a port facility also located in the Browse LNG Precinct. The onshore project was abandoned by the joint venture after Australia's rising costs made the project unviable. This project is now to be developed as a floating LNG facility with minimal construction work to be undertaken in Australia. Joint venture , the owners of the joint venture were: *Woodside Petroleum (Operator) *Shell * BP *Japan Australia LNG (MIMI Browse) (a joint venture of Mitsubishi and Mitsui) *BHP Billiton In December 2012, PetroChina agreed to buy BHP Billiton's 8.3% stake in the East Browse and 20% holding ...

Seabed
The seabed (also known as the seafloor, sea floor, ocean floor, and ocean bottom) is the bottom of the ocean. All floors of the ocean are known as 'seabeds'. The structure of the seabed of the global ocean is governed by plate tectonics. Most of the ocean is very deep, where the seabed is known as the abyssal plain. Seafloor spreading creates mid-ocean ridges along the center line of major ocean basins, where the seabed is slightly shallower than the surrounding abyssal plain. From the abyssal plain, the seabed slopes upward toward the continents and becomes, in order from deep to shallow, the continental rise, slope, and shelf. The depth within the seabed itself, such as the depth down through a sediment core, is known as the “depth below seafloor.” The ecological environment of the seabed and the deepest waters are collectively known, as a habitat for creatures, as the “benthos.” Most of the seabed throughout the world's oceans is covered in layers of marine sediments. ...

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] |
Continental Shelf
A continental shelf is a portion of a continent that is submerged under an area of relatively shallow water, known as a shelf sea. Much of these shelves were exposed by drops in sea level during glacial periods. The shelf surrounding an island is known as an ''insular shelf''. The continental margin, between the continental shelf and the abyssal plain, comprises a steep continental slope, surrounded by the flatter continental rise, in which sediment from the continent above cascades down the slope and accumulates as a pile of sediment at the base of the slope. Extending as far as 500 km (310 mi) from the slope, it consists of thick sediments deposited by turbidity currents from the shelf and slope. The continental rise's gradient is intermediate between the gradients of the slope and the shelf. Under the United Nations Convention on the Law of the Sea, the name continental shelf was given a legal definition as the stretch of the seabed adjacent to the shores of a par ...
