Fringing reefA fringing reef is one of the three main types of coral reef. It is distinguished from the other main types, barrier reefs and atolls, in that it has either an entirely shallow backreef zone (lagoon) or none at all. If a fringing reef grows directly from the shoreline, then the reef flat extends to the beach and there is no backreef. In other cases (e.g., most of the Bahamas), fringing reefs may grow hundreds of yards from shore and contain extensive backreef areas within which it contains food and water, examples are Philippines, Indonesia, Timor-Leste, the western coast of Australia, the Caribbean, East Africa, and Red Sea.
Caroline IslandsThe Caroline Islands (or the Carolines) are a widely scattered archipelago of tiny islands in the western Pacific Ocean, to the north of New Guinea. Politically, they are divided between the Federated States of Micronesia (FSM) in the central and eastern parts of the group, and Palau at the extreme western end. Historically, this area was also called Nuevas Filipinas or New Philippines, because they were part of the Spanish East Indies and were governed from Manila in the Philippines.
AtollAn atoll (pronˈæt.ɒl,-ɔːl,-oʊl,əˈtɒl,-ˈtɔːl,_-ˈtoʊl) is a ring-shaped island, including a coral rim that encircles a lagoon. There may be coral islands or cays on the rim. Atolls are located in warm tropical or subtropical parts of the 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.
KiribatiKiribati (ˌkɪrᵻˈbæs ), officially the Republic of Kiribati ([Ribaberiki] Kiribati), is an island country in Micronesia subregion of Oceania in the central Pacific Ocean. Its permanent population is over 119,000 as of 2020 census, with more than half living on Tarawa atoll. The state comprises 32 atolls and one remote raised coral island, Banaba. Its total land area is dispersed over of ocean. The islands' spread straddles the equator and the 180th meridian, although the International Date Line goes around Kiribati and swings far to the east, almost reaching 150°W.
Coral reefA coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups. Coral belongs to the class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons that support and protect the coral. Most reefs grow best in warm, shallow, clear, sunny and agitated water.
PalauPalau (officially the Republic of Palau and historically Belau, Palaos or Pelew) is an island country in the Micronesia subregion of Oceania in the western Pacific. The republic consists of approximately 340 islands and connects the western chain of the Caroline Islands with parts of the Federated States of Micronesia. It has a total area of , making it one of the smallest countries in the world. The most populous island is Koror, home to the country's most populous city of the same name.
MaldivesThe Maldives (ˈmɑːldivz ; ދިވެހިރާއްޖެ, diʋehi ɾaːd͡ʒːe), officially the Republic of Maldives (ދިވެހިރާއްޖޭގެ ޖުމްހޫރިއްޔާ, diʋehi ɾaːd͡ʒːeːge d͡ʒumhuːɾijjaː), is an archipelagic state and country in South Asia, situated in the Indian Ocean. It lies southwest of Sri Lanka and India, about from the Asian continent's mainland. The Maldives' chain of 26 atolls stretches across the equator from Ihavandhippolhu Atoll in the north to Addu Atoll in the south.
MicronesiansThe Micronesians or Micronesian peoples are various closely related ethnic groups native to Micronesia, a region of Oceania in the Pacific Ocean. They are a part of the Austronesian ethnolinguistic group, which has an Urheimat in Taiwan. Ethno-linguistic groups classified as Micronesian include the Carolinians (Northern Mariana Islands), Chamorros (Guam & Northern Mariana Islands), Chuukese, Mortlockese, Namonuito, Paafang, Puluwat and Pollapese (Chuuk), I-Kiribati (Kiribati), Kosraeans (Kosrae), Marshallese (Marshall Islands), Nauruans (Nauru), Palauan, Sonsorolese, and Hatohobei (Palau), Pohnpeians, Pingelapese, Ngatikese, Mwokilese (Pohnpei), and Yapese, Ulithian, Woleian, Satawalese (Yap).
