Timor Trough
The Timor Trough is an oceanic trough that is a continuation of the Sunda Trench (Java Trench) that marks the boundary between the Indo-Australian plate and the Timor plate. It is separated from the Sunda Trench by a sag near Sumba Island at the Scott Plateau and the North Australian Basin, and on the other end becomes the Tanimbar Trough southeast of the Tanimbar Islands, continuing on to the Aru Trough east of the Kai Islands near the Bird's Head Peninsula on New Guinea. Lining the north of the trough are numerous islands, of which Timor is the largest. Further west are the Weber Basin and the Banda Trench. Oil and natural gas Natural gas (also fossil gas, methane gas, and gas) is a naturally occurring compound of gaseous hydrocarbons, primarily methane (95%), small amounts of higher alkanes, and traces of carbon dioxide and nitrogen, hydrogen sulfide and helium ... have been found in the Bonaparte Basin south of the trough and the region is geologically active with ...

Trough (geology)
In geology, a trough is a linear structural depression that extends laterally over a distance. Although it is less steep than a ''trench'', a trough can be a narrow basin or a geologic rift. These features often form at the rim of tectonic plates. There are various oceanic troughs on the ocean floors. Examples of oceanic troughs * Benue Trough * Cayman Trough * Hesperides Trough * Kings Trough * Mariana Trough * Nankai Trough * Northumberland Trough * Okinawa Trough in the East China Sea * Rockall Trough and others along the rift of the mid-oceanic ridge * Salton Trough * South Shetland Trough * Suakin TroughDinwiddie, Robert et al.

Bird's Head Peninsula
The Bird's Head Peninsula ( Indonesian: , , meaning Bird's Head in Indonesian and Dutch) or Doberai Peninsula (''Semenanjung Doberai'') is a large peninsula that makes up the northwest portion of the island of New Guinea, comprising the Indonesian provinces of Southwest Papua and West Papua. It is often referred to as The Vogelkop, and is so named because its shape looks like a bird's head on the island of New Guinea. The peninsula at the opposite end of the island (in Papua New Guinea) is called the Bird's Tail Peninsula. The peninsula just to the south is called the Bomberai Peninsula. Location and geography The Bird's Head Peninsula is at the northwestern end of the island of New Guinea. It is bounded by Cenderawasih Bay to the east, Bintuni Bay to the south, and the Dampier Strait to the west. Across the strait is Waigeo, an island in the Raja Ampat archipelago. Batanta island lies just off the peninsula’s northwest tip. Another peninsula, Bomberai Peninsula, l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bonaparte Basin
The Bonaparte Basin is a sedimentary basin in Western Australia and the Northern Territory of Australia. Its total area is approximately , most of which is offshore. The sedimentary basin emerges at the Joseph Bonaparte Gulf and extends into the ocean in the waters of the gulf and the Timor Sea. It partially overlays the Pine Creek Orogen and the Fitzmaurice Basin. It is bounded on the north by the Timor Trough, on the west by the Browse Basin and on the northeast by the Money Shoals Basin. In the sedimentary basin the rock strata is about thick on land, and over thick under the ocean. The basin originated from the Cambrian period to the Cenozoic era, 540 to 360 million years ago. Limestone, sandstone, mudstone, basalt, coal and glacial sediments are embedded in the basin. It contains several oil and natural gas fields amounting to 18% of Australia's known reserves of natural gas. Total estimated reserves are of oil and of gas. The sedimentary basin partially overla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Gas
Natural gas (also fossil gas, methane gas, and gas) is a naturally occurring compound of gaseous hydrocarbons, primarily methane (95%), small amounts of higher alkanes, and traces of carbon dioxide and nitrogen, hydrogen sulfide and helium. Methane is a colorless and odorless gas, and, after carbon dioxide, is the second-greatest greenhouse gas that contributes to global climate change. Because natural gas is odorless, a commercial odorizer, such as Methanethiol (mercaptan brand), that smells of hydrogen sulfide (rotten eggs) is added to the gas for the ready detection of gas leaks. Natural gas is a fossil fuel that is formed when layers of organic matter (primarily marine microorganisms) are thermally decomposed under oxygen-free conditions, subjected to intense heat and pressure underground over millions of years. The energy that the decayed organisms originally obtained from the sun via photosynthesis is stored as chemical energy within the molecules of methane and other ...

Weber Basin
Location of the Banda Sea in Southeast Asia Weber Deep () is the deepest point in the Banda Sea off Indonesia. Weber Deep maximum depth is 7,351 meters, (24,117 feet, 4.56 miles). Banda Sea is connected to the Pacific Ocean, near the Maluku Islands of Indonesia in the Banda Arc. Weber Deep differs from other deep sea points in that Weber Deep is not a deep sea trench, but is a forearc basin, a deep abyssal plain. The slab detachment is at the east end of the deep. Weber Deep is the 16th deepest point in the Earth's oceans and seas. Researchers believe that the Weber Deep was formed when part of the Earth's crust broke off along a 120 km (75 miles) extension of a fault on the ring of fire, called the Banda Detachment. The break-off was caused by plate tectonics creating a back-arc basin rip in the ocean floor. In parts of Weber Deep there is no oceanic crust on the sea floor due to the rip. The rip is approximately 60,000 km2 (23,166 miles2). Researchers believe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Timor
Timor (, , ) is an island at the southern end of Maritime Southeast Asia, in the north of the Timor Sea. The island is Indonesia–Timor-Leste border, divided between the sovereign states of Timor-Leste in the eastern part and Indonesia in the western part. The Indonesian part, known as West Timor, constitutes part of the Provinces of Indonesia, province of East Nusa Tenggara. Within West Timor lies an exclave of Timor-Leste called Oecusse District. The island covers an area of . The name is a variant of ''timur'', Malay language, Malay for "east"; it is so called because it lies at the eastern end of the Lesser Sunda Islands. Mainland Australia is less than 500 km away, separated by the Timor Sea. Language, ethnic groups and religion Anthropologists identify eleven distinct Ethnolinguistic group, ethno-linguistic groups in Timor. The largest are the Atoni of western Timor and the Tetum language, Tetum of central and eastern Timor. Most indigenous Timorese languages ...

New Guinea
New Guinea (; Hiri Motu: ''Niu Gini''; , fossilized , also known as Papua or historically ) is the List of islands by area, world's second-largest island, with an area of . Located in Melanesia in the southwestern Pacific Ocean, the island is separated from Mainland Australia, Australia by the wide Torres Strait, though both landmasses lie on the same continental shelf, and were united during episodes of low sea level in the Pleistocene glaciations as the combined landmass of Sahul. Numerous smaller islands are located to the west and east. The island's name was given by Spanish explorer Yñigo Ortiz de Retez during his maritime expedition of 1545 due to the perceived resemblance of the indigenous peoples of the island to those in the Guinea (region), African region of Guinea. The eastern half of the island is the major land mass of the nation of Papua New Guinea. The western half, known as Western New Guinea, forms a part of Indonesia and is organized as the provinces of Pap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kai Islands
The Kai Islands (also Kei Islands) of Indonesia are a group of islands in the southeastern part of the Maluku Islands, located in the province of Maluku (province), Maluku. The Moluccas have been known as the Spice Islands due to regionally specific plants such as nutmeg, mace (spice), mace, and cloves that originally intrigued the European nations of the 16th century. The coastal zone of the islands are identified as a site of highest marine biodiversity importance in the Coral Triangle. Geography The Kai Islands are a part of the Wallacea, the group of Indonesian islands that are separated by deep water from both the Asian and Australia (continent), Australian continental shelf, continental shelves, and were never linked to either continent. As a result, the Kai Islands have few native mammals and are a part of the Banda Sea Islands moist deciduous forests ecoregion. Kai Besar in particular is mountainous and densely forested. Kai is famous for the beauty of its beaches, n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sunda Trench
The Sunda Trench, earlier known as and sometimes still indicated as the Java Trench, is an oceanic trench located in the Indian Ocean near Sumatra, formed where the Australian- Capricorn plates subduct under a part of the Eurasian plate. It is long with a maximum depth of 7,290 metres (23,920 feet). Its maximum depth is the deepest point in the Indian Ocean. The trench stretches from the Lesser Sunda Islands past Java, around the southern coast of Sumatra to the Andaman Islands, and forms the boundary between the Indo-Australian plate and Eurasian plate (more specifically, Sunda plate). The trench is considered to be part of the Alpide belt as well as one of oceanic trenches around the northern edges of the Australian plate. In 2005, scientists found evidence that the 2004 earthquake activity in the area of the Java Trench could lead to further catastrophic shifting within a relatively short period, perhaps less than a decade. This threat has resulted in international agreem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tanimbar Islands
The Tanimbar Islands (; ), also called ''Timur Laut'' (literally, "North East"; ), are a group of about 65 islands in the Maluku province of Indonesia. The largest and most central of the islands is Yamdena; others include Selaru to the southwest of Yamdena, Larat and Fordata to the northeast, Maru and Molu to the north, and Seira, Wuliaru, Selu, Wotap and Makasar to the west. The Indonesian phrase ''timur laut'' means "east of the sea" or "northeast". The Tanimbar Islands are administered as the '' Tanimbar Islands Regency'' (), a regency of Maluku. The Regency covers a land area of 10,102.92 km2, and it had a population of 105,341 at the 2010 census, rising to 123,572 at the 2020 census;Badan Pusat Statistik, Jakarta, 2021. the official estimate as at mid 2023 was 130,278.Badan Pusat Statistik, Jakarta, 2023, ''Provinsi Maluku Dalam Angka 2023'' (Katalog-BPS 1102001.81) The principal town and administrative centre lies at Saumlaki.

North Australian Basin
The North Australian Basin (NAB; formerly Argo Abyssal Plain, or Argo Plain) is an oceanic basin in the easternmost corner of the Indian Ocean between northwest Australia and Indonesia. It was discovered by the U.S. research vessel "Argo" of the Scripps Institution of Oceanography in 1960. It should be distinguished from an Australian sedimentary basin with the same name.C Heine &RD MüllerLate Jurassic rifting along the Australian North West Shelf: margin geometry and spreading ridge configuration An International Geoscience Journal of the Geological Society of Australia Volume 52, 2005 - Issue 1, pp. 27-39 It bounds the Australian continental margin in the area of its northwestern shelf. From the north, east, south and southwest it is respectively bounded by the Java Trench, the submerged continental crust of the Scott Plateau, Rowley Terrace, and the Exmouth Planeau with the Wombat Plateau.
