Coron Island
Coron is the third-largest island in the Calamian Islands in northern Palawan in the Philippines. The island is part of the larger municipality of the same name. It is about southwest of Manila and is known for several Japanese shipwrecks of World War II vintage. Because of its unique ecological features, the entire area is protected by several legal proclamations. The island and surrounding fishing grounds are part of the ancestral domain of the indigenous Tagbanwa people, officially designated such on June 5, 1998. Known as Calis among the Tagbanwas and Coronians, its tribal chieftain is Rodolfo Aguilar I. The island comprises two barangays of the municipality of Coron: Banuang Daan and Cabugao. Geography Partially between Busuanga and Culion islands, Coron Island faces the Sulu Sea and forms the eastern side of Coron Bay. It is about long from north to south, and at its widest point. Part of the North Palawan Block, Coron Island is distinguished by its Late Triassic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calamian Group Of Islands
The Calamian Islands or the Calamianes is a group of islands in the province of Palawan, Philippines. It includes: * Busuanga Island * Coron Island * Culion Island * Calauit Island * Malcapuya Island * Banana Island * Pass Island * Calumbuyan Island * ''several minor islets'' History Historically, the Calamianes was site of the Spanish politico-militar ''Provincia de Calamianes''. It became the site of a Presidio or a Spanish military garrison, and the small group of islands received, almost 100 Spanish and Mexican soldier-colonists in the 1670s. The Spanish Empire later purchased mainland Paragua from the Sultan of Borneo. During the American occupation (1898-1948), the old ''Provincia de Calamianes'' was dissolved and jointly administered with the Island of Paragua as the new Province of Palawan. During the American occupation and up until recently, Culion Island was host to a leper colony. Busuanga Island hosts the largest town, Coron, in the Calamian Islands. Coron Island ...

Busuanga Island
Busuanga, is the largest island in the Calamian Group of islands in the province of Palawan in the Philippines. Busuanga Island is the second largest island in the province after Palawan island itself. The island is located halfway between the islands of Mindoro and Palawan with the South China Sea located to the west and the Sulu Sea to the southeast. South of the island are the two other major islands of the Calamian Group: Culion Island and Coron Island. The western third of the island is under the municipality of Busuanga and the eastern two-thirds belong to the municipality of Coron. Busuanga Island is known as a recreational diving location due to World War II Japanese wrecks that were sunk by American navy bombings in Coron Bay, a natural anchorage near the town center of Coron, on September 24, 1944. Geology Part of the North Palawan Block, Busuanga Island consists mainly of the Liminangcong Formation, a Permian to Late Jurassic chert. This chert forms the distingui ...

Japanese Seaplane Tender Akitsushima
was a seaplane tender of the Imperial Japanese Navy (IJN), serving during World War II from 1942 until being sunk in September 1944. Design In 1938, the IJN wanted to use their large-sized flying boats more effectively, because the Kawanishi H6K was the only aircraft able to hit Pearl Harbor directly from the Marshall Islands. However, the Marshall Islands did not have flying boat facilities at that time. Early in 1939, the IJN converted the oiler to a seaplane tender. However, she was not able to repair seaplanes. The IJN therefore planned two kinds of seaplane tenders which were included in the Maru 4 Programme. One was a 10,000-ton class flying boat carrier, the other a 2,400-ton class flying boat tender. These plans were not able to pass the assessment by the Ministry of Finance. These two basic plans were revived by the Maru 5 Programme in 1941. However, their construction did not begin. Therefore, the IJN planned a 3,500-ton class tender, which was a scaled-up model ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wreck Diving
Wreck diving is recreational diving where the wreckage of ships, aircraft and other artificial structures are explored. Although most wreck dive sites are at shipwrecks, there is an increasing trend to scuttle retired ships to create artificial reef sites. Diving to crashed aircraft can also be considered wreck diving. The recreation of wreck diving makes no distinction as to how the vessel ended up on the bottom. Some wreck diving involves penetration of the wreckage, making a direct ascent to the surface impossible for a part of the dive. Reasons for diving wrecks A shipwreck may be attractive to divers for several reasons: * it serves as an artificial reef, which creates a habitat for many types of marine life * it often is a large structure with many interesting parts and machinery, which is not normally closely observable on working, floating vessels * it often has an interesting history * it presents new skill challenges for scuba divers to manage the risks associate ...

Snorkeling
Snorkeling ( British and Commonwealth English spelling: snorkelling) is the practice of swimming on or through a body of water while equipped with a diving mask, a shaped breathing tube called a snorkel, and usually swimfins. In cooler waters, a wetsuit may also be worn. Use of this equipment allows the snorkeler to observe underwater attractions for extended periods with relatively little effort and to breathe while face-down at the surface. Snorkeling is a popular recreational activity, particularly at tropical resort locations. It provides the opportunity to observe underwater life in a natural setting without the complicated equipment and training required for scuba diving. It appeals to all ages because of how little effort is involved and is the basis of the two surface disciplines of the underwater sport of finswimming. Snorkeling is also used by scuba divers when on the surface, in underwater sports such as underwater hockey and underwater rugby, and as part of water-b ...

Mangrove
A mangrove is a shrub or tree that grows in coastal saline water, saline or brackish water. The term is also used for tropical coastal vegetation consisting of such species. Mangroves are taxonomically diverse, as a result of convergent evolution in several plant families. They occur worldwide in the tropics and subtropics and even some temperate coastal areas, mainly between latitudes 30° N and 30° S, with the greatest mangrove area within 5° of the equator. Mangrove plant families first appeared during the Late Cretaceous to Paleocene epochs, and became widely distributed in part due to the plate tectonics, movement of tectonic plates. The oldest known fossils of Nypa fruticans, mangrove palm date to 75 million years ago. Mangroves are salt-tolerant trees, also called halophytes, and are adapted to live in harsh coastal conditions. They contain a complex salt filtration system and a complex root system to cope with saltwater immersion and wave action. They are ad ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Triassic
The Late Triassic is the third and final epoch (geology), epoch of the Triassic geologic time scale, Period in the geologic time scale, spanning the time between annum, Ma and Ma (million years ago). It is preceded by the Middle Triassic Epoch and followed by the Early Jurassic Epoch. The corresponding series (stratigraphy), series of rock beds is known as the Upper Triassic. The Late Triassic is divided into the Carnian, Norian and Rhaetian Geologic time scale, Ages. Many of the first dinosaurs evolved during the Late Triassic, including ''Plateosaurus'', ''Coelophysis'', and ''Eoraptor''. The Triassic–Jurassic extinction event began during this epoch and is one of the five major mass extinction events of the Earth. Etymology The Triassic was named in 1834 by Friedrich August von Namoh, Friedrich von Alberti, after a succession of three distinct rock layers (Greek meaning 'triad') that are widespread in southern Germany: the lower Buntsandstein (colourful sandstone'')'', t ...

North Palawan Block
North Palawan Block is a microcontinental block situated in the western Philippines and the southern tip of the Manila Trench. The North Palawan block is considered to form the northeastern portion of a much larger area of block faulted and foundered pre-Tertiary continental material which extends throughout the southern part of the South China Sea Basin and includes the Spratly Islands and the Dangerous Grounds area off Borneo (Hamilton, 1979). The evidence for the continental composition of the crust of this area is substantial and has been reviewed by Hamilton (1979) and Taylor & Hayes (1980) among others. Geology The geology of the North Palawan Block includes terrane found on four islands: North Palawan, Romblon Island Group, Northeast Mindoro and Buruanga Peninsula. The stratigraphy found on Northern Palawan starts with the Middle Permian to Late Permian Bacuit Formation, , a sequence of sandstone, altered tuff, calcareous sandstone, chert, and slate. It forms the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coron Bay
Coron Bay is a well-known recreational diving region in the Sulu Sea in the western Philippines, between the islands of Coron and Busuanga in the Calamian Islands. Most of Coron Bay is in the Coron Island Protected Area and is a traditional fishing area of the indigenous Tagbanwa tribe. Coron Bay is famous for diving on ten Japanese shipwrecks. The ships , ''Okikawa Maru'', , ''Kogyo Maru'', ''Olympia Maru'', ''Taiei Maru'', ''Kyokuzan Maru'', East Tangat Gunboat and Lusong Island Gunboat were sunk on September 24, 1944, by the third air fleet of US Task Force 38. The wrecks can be reached in a one-hour drive from Coron by dive boat. With the exception of the Lusong Island Gunboat, which partially breaks through the water surface and is therefore suitable for snorkelers, and the East Tangat Gunboat, which is suitable for beginners at a depth of 5 to 20 m, all other wrecks lie at depths of 20 to 45 m. Some of the wrecks are over 100 m long and have decks, corridors, galleys etc. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
