Islands Of Tuvalu
Tuvalu consists of nine separate islands: six atolls and three reef islands. An atoll typically consists of several islets: Tuvalu has a total of 124 islands and islets. Each island is surrounded by a coral reef. Tuvalu's small, widely scattered atolls have poor soil and a total land area of only about making Tuvalu the fourth-smallest country in the world. The sea level at the Funafuti tide gauge has been rising at a rate of 3.9 mm per year, and it has been determined that rising sea levels are causing more wave energy to be transferred across reef surfaces, which has tended to push more sand onto island shorelines, increasing islands’ land area. Over a recent four-decade period, there was a net increase in the land area of the islets of 2.9% (73.5 ha), although the changes were not uniform: About 74% of them increased in size and about 27% decreased in size.

Tuvalu
Tuvalu ( or ; formerly known as the Ellice Islands) is an island country and microstate in the Polynesian subregion of Oceania in the Pacific Ocean. Its islands are situated about midway between Hawaii and Australia. They lie east-northeast of the Santa Cruz Islands (which belong to the Solomon Islands), northeast of Vanuatu, southeast of Nauru, south of Kiribati, west of Tokelau, northwest of Samoa and Wallis and Futuna, and north of Fiji. Tuvalu is composed of three reef islands and six atolls. They are spread out between the latitude of 5th parallel south, 5° and 10th parallel south, 10° south and between the longitude of 176th meridian east, 176° and 180th meridian, 180°. They lie west of the International Date Line. Tuvalu has a population of 10,507 (2017 census). The total land area of the islands of Tuvalu is . The first inhabitants of Tuvalu were Polynesians, according to well-established theories regarding a History of the Polynesian people, migration of Polynes ...

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] |

Nanumea
Nanumea is the northwesternmost atoll in the Polynesian nation of Tuvalu, a group of nine coral atolls and islands spread over about of the Pacific Ocean just south of the equator and west of the International Date Line. Nanumea is with a population of 512 people (2017 census). Geography Located along one edge of the so-called Polynesian triangle, Nanumea lies just south of the Gilbert Islands, which are Micronesian in language and culture. Nanumea is a classic atoll, a series of low islets sitting on a coral reef shelf surrounding a lagoon. About long by wide in overall size, the dry land area is about . The two largest islets Nanumea and Lakena, which comprise 90% of the dry land area of the atoll. Since the early 1990s, the use of nets and spearing has been prohibited in all parts of the lagoon and the Nanumea Conservation Area was established in 2006. The Nanumea Conservation Area covers about of the central lagoon and consists of about 10% of the reef area of the atol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vaiaku
Vaiaku is a village located on the southern coast of the island of Fongafale in the atoll of Funafuti in Tuvalu. There are 516 inhabitants in Vaiaku, according to the census of 2002, out of 4,492 for the whole atoll of Funafuti, which is the official capital of Tuvalu. All the administrative buildings, including the National Bank of Tuvalu, and the only hotel of Tuvalu, Vaiaku Langi Hotel, are located in Vaiaku.

Funafuti
Funafuti is the capital of the island nation of Tuvalu. It has a population of 6,320 people (2017 census), and so it has more people than the rest of Tuvalu combined, with approximately 60% of the population. It consists of a narrow sweep of land between wide, encircling a large lagoon (''Te Namo'') long and wide. The average depth of the Funafuti lagoon is about 20 fathoms (36.5 metres or 120 feet). With a surface area of , it is by far the largest lagoon in Tuvalu. The land area of the 33 islets around the atoll of Funafuti totals ; taken together, they constitute less than one percent of the total area of the atoll. Cargo ships can enter Funafuti's lagoon and dock at the port facilities on Fongafale. The capital of Tuvalu is sometimes said to be Fongafale or Vaiaku, but, officially, the entire atoll of Funafuti is its capital, since it has a single government that is responsible for the whole atoll. Fongafale The largest island is Fongafale. The island houses four villag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atolls
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 b ...

Geographic Coordinate System
The geographic coordinate system (GCS) is a spherical or ellipsoidal coordinate system for measuring and communicating positions directly on the Earth as latitude and longitude. It is the simplest, oldest and most widely used of the various spatial reference systems that are in use, and forms the basis for most others. Although latitude and longitude form a coordinate tuple like a cartesian coordinate system, the geographic coordinate system is not cartesian because the measurements are angles and are not on a planar surface. A full GCS specification, such as those listed in the EPSG and ISO 19111 standards, also includes a choice of geodetic datum (including an Earth ellipsoid), as different datums will yield different latitude and longitude values for the same location. History The invention of a geographic coordinate system is generally credited to Eratosthenes of Cyrene, who composed his now-lost ''Geography'' at the Library of Alexandria in the 3rd century ...

Census
A census is the procedure of systematically acquiring, recording and calculating information about the members of a given population. This term is used mostly in connection with national population and housing censuses; other common censuses include censuses of agriculture, traditional culture, business, supplies, and traffic censuses. The United Nations (UN) defines the essential features of population and housing censuses as "individual enumeration, universality within a defined territory, simultaneity and defined periodicity", and recommends that population censuses be taken at least every ten years. UN recommendations also cover census topics to be collected, official definitions, classifications and other useful information to co-ordinate international practices. The UN's Food and Agriculture Organization (FAO), in turn, defines the census of agriculture as "a statistical operation for collecting, processing and disseminating data on the structure of agriculture, covering th ...

Flag Of Tuvalu-(star Interpretation)
A flag is a piece of fabric (most often rectangular or quadrilateral) with a distinctive design and colours. It is used as a symbol, a signalling device, or for decoration. The term ''flag'' is also used to refer to the graphic design employed, and flags have evolved into a general tool for rudimentary signalling and identification, especially in environments where communication is challenging (such as the maritime environment, where semaphore is used). Many flags fall into groups of similar designs called flag families. The study of flags is known as "vexillology" from the Latin , meaning "flag" or "banner". National flags are patriotic symbols with widely varied interpretations that often include strong military associations because of their original and ongoing use for that purpose. Flags are also used in messaging, advertising, or for decorative purposes. Some military units are called "flags" after their use of flags. A ''flag'' (Arabic: ) is equivalent to a brigad ...
