Ootu Peninsula
The Ootu Peninsula, though connected to the main island of Aitutaki atoll of the Cook Islands, may in many respects be considered as one of the reef islands, being the largest and longest of them. It is located at the northern end of the eastern perimeter of Aitutaki Lagoon to the north and then west of the northernmost true reef island, Akitua, from which is separated by a channel 50 metres wide and less than two metres deep. The southernmost point of the peninsula is called ''Aumoana''. The northernmost point of the peninsula, ''Teaumera'', is also the northernmost point of Aitutaki as a whole. In the northeast is ''Kopu a Ruatapu'', a boat passage through the fringing coral reef. The peninsula is 3.25 km long north–south, and has an area of 1.75 km2. It is 400 metres wide on the average, with a minimum of 250 metres. At its widest, where it joins the main island, it reaches 750 metres in with. By comparison, Tekopua, the largest true reef island of Aitutaki, is 2.25& ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aitutaki
Aitutaki, also traditionally known as Araura and Utataki, is the second most-populated island in the Cook Islands, after Rarotonga. It is an "almost atoll", with fifteen islets in a lagoon adjacent to the main island. Total land area is , and the lagoon has an area of between . A major tourist destination, Aitutaki is the second most visited island of the Cook Islands. Aitutaki had a population of 1,712 in 2016. The main village is Arutanga (Arutunga) on the west side. Geography Aitutaki is sometimes described as an "almost atoll", for it consists of a lagoon within an encircling atoll, with a significant area of high land on one side. It has a maximum elevation of approximately with the hill known as Maunga Pu close to its northernmost point. The land area of the atoll is , of which the main island occupies . The Ootu Peninsula, protruding east from the main island in a southerly direction along the eastern rim of the reef, takes up out of the main island. For the lagoon, are ...

Atoll
An atoll () is a ring-shaped island, including a coral rim that encircles a lagoon partially or completely. There may be coral islands or cays on the rim. Atolls are located in warm tropical or subtropical oceans and seas where corals can grow. Most of the approximately 440 atolls in the world are in the Pacific Ocean. Two different, well-cited models, the subsidence and antecedent karst models, have been used to explain the development of atolls.Droxler, A.W. and Jorry, S.J., 2021. ''The Origin of Modern Atolls: Challenging Darwin's Deeply Ingrained Theory.'' ''Annual Review of Marine Science'', 13, pp.537-573. According to Charles Darwin's ''subsidence model'', the formation of an atoll is explained by the subsidence of a volcanic island around which a coral fringing reef has formed. Over geologic time, the volcanic island becomes extinct and eroded as it subsides completely beneath the surface of the ocean. As the volcanic island subsides, the coral fringing reef becomes a ...

Reef
A reef is a ridge or shoal of rock, coral or similar relatively stable material, lying beneath the surface of a natural body of water. Many reefs result from natural, abiotic processes— deposition of sand, wave erosion planing down rock outcrops, etc.—but there are also reefs such as the coral reefs of tropical waters formed by biotic processes dominated by corals and coralline algae, and artificial reefs such as shipwrecks and other anthropogenic underwater structures may occur intentionally or as the result of an accident, and sometimes have a designed role in enhancing the physical complexity of featureless sand bottoms, to attract a more diverse assemblage of organisms. Reefs are often quite near to the surface, but not all definitions require this. Earth's largest coral reef system is the Great Barrier Reef in Australia, at a length of over . Biotic There is a variety of biotic reef types, including oyster reefs and sponge reefs, but the most massive and widely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lagoon
A lagoon is a shallow body of water separated from a larger body of water by a narrow landform, such as reefs, barrier islands, barrier peninsulas, or isthmuses. Lagoons are commonly divided into ''coastal lagoons'' (or ''barrier lagoons'') and ''atoll lagoons''. They have also been identified as occurring on mixed-sand and gravel coastlines. There is an overlap between bodies of water classified as coastal lagoons and bodies of water classified as estuaries. Lagoons are common coastal features around many parts of the world. Definition and terminology Lagoons are shallow, often elongated bodies of water separated from a larger body of water by a shallow or exposed shoal, coral reef, or similar feature. Some authorities include fresh water bodies in the definition of "lagoon", while others explicitly restrict "lagoon" to bodies of water with some degree of salinity. The distinction between "lagoon" and "estuary" also varies between authorities. Richard A. Davis Jr. restrict ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dune
A dune is a landform composed of wind- or water-driven sand. It typically takes the form of a mound, ridge, or hill. An area with dunes is called a dune system or a dune complex. A large dune complex is called a dune field, while broad, flat regions covered with wind-swept sand or dunes with little or no vegetation are called ''ergs'' or ''sand seas''. Dunes occur in different shapes and sizes, but most kinds of dunes are longer on the stoss (upflow) side, where the sand is pushed up the dune, and have a shorter ''slip face'' in the lee side. The valley or trough between dunes is called a ''dune slack''. Dunes are most common in desert environments, where the lack of moisture hinders the growth of vegetation that would otherwise interfere with the development of dunes. However, sand deposits are not restricted to deserts, and dunes are also found along sea shores, along streams in semiarid climates, in areas of glacial outwash, and in other areas where poorly cemented sa ...

Aitutaki Airport
Aitutaki Airport is the airport for Aitutaki, one of the Cook Islands . The airport was originally constructed by the United States and New Zealand militaries during World War II. The runway was upgraded in 2004. The terminal building at Aitutaki Airport is a roof with no or few windows. There is a small convenience stall where snacks and drinks can be purchased. Resort meet-and-greet stalls are also inside the terminal. Air Rarotonga serves Aitutaki with Saab 340A and Embraer Bandeirante The Embraer EMB 110 Bandeirante (English: ''pioneer'') is a Brazilian general purpose 15–21 passenger twin-turboprop light transport aircraft designed by Embraer for military and civil use.

Tapere
A Tapere or Sub-District is a low level of traditional land subdivision on five of the Southern Cook Islands (Rarotonga, Mangaia, Aitutaki, Atiu, and Mauke), comparable to the ahupua'a of the main Hawaiian Islands or to the kousapw of Pohnpei. Among the populated raised islands, only Mitiaro is not subdivided into tapere. The remaining Southern Cook Islands, Manuae, Palmerston and Takutea are atolls and/or uninhabited, and therefore not subject to this type of traditional subdivision. The atolls of the Northern Cook Islands are subdivided into ''motu'' (populated atoll islets), instead. A tapere is a subdivision of a district (the major island subdivision) or ''puna'', which is headed by a district chiefs or ''Pava'' (in the case of the Island of Mangaia). A tapere is normally headed by a ''mataiapo'' (a chief of a major lineage) or ''ariki'' (a High Chief, the titular head of a tribe). It is occupied by the ''matakeinanga'', the local group composed of the residential core of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landforms Of The Cook Islands
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are the fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
