This is a list of seas of the World Ocean , including marginal seas, areas of water, various gulfs , bights , bays , and straits . In many cases it is a matter of tradition for a body of water to be named a sea or a bay, etc., therefore all these types are listed here.
39-627: The Philippine Sea is a marginal sea of the Western Pacific Ocean east of the Philippine Archipelago (hence the name) and the largest sea in the world , occupying an estimated surface area of 5 million square kilometers (2 × 10 ^ sq mi). The Philippine Sea Plate forms the floor of the sea. Its western border is the first island chain to the west, comprising the Ryukyu Islands in
78-419: A negative effect on local sources of livelihood, such as fishing and tourism. It is also making the waters warmer, which endangers corals. Warmer water causes corals to absorb more carbon dioxide. This alters the water's pH balance, making it acidic, a condition to which the corals are not adapted, and in which they are ill-equipped to survive. The Philippine Sea hosts an exotic marine ecosystem. There are 421 of
117-439: Is a centre of marine biodiversity as well as a biodiversity hotspot . However, at least 418 species are being threatened because of unsustainable practices. The rise in temperature change caused shifts in the marine ecosystems . which could cause corals to die due to changing sea temperature. As fish and other marine life rely on corals for sustenance and habitat, communities that rely on fishing are heavily affected as well. As
156-1057: Is a rich fishing ground for fishermen from Aurora, Quezon and Bicol. The Philippines Bureau of Fisheries and Aquatic Resources trains fishermen in sustainable-fishing techniques to prevent the destruction of coral formations, which could negatively affect the food chain that the migratory fish depend on. Migratory fish generally sell at high prices. For example, a single bluefin tuna from the Benham Rise can be sold at market for ₱2,000 . 20°N 130°E / 20°N 130°E / 20; 130 List of seas#Marginal seas by ocean There are several terms used for bulges of ocean that result from indentations of land, which overlap in definition, and which are not consistently differentiated: Many features could be considered to be more than one of these, and all of these terms are used in place names inconsistently; especially bays, gulfs, and bights, which can be very large or very small. This list includes large areas of water no matter
195-820: Is approximately 2 million square kilometers. It encompasses the tropical waters of Malaysia , Indonesia , the Philippines , Timor-Leste , Papua New Guinea , and Solomon Islands . The Philippine islands, which lie at its apex, make up 300,000 square kilometers (120,000 sq mi) of it. The part of the Coral Triangle's coral reef area that lies within the Philippines ranges from 10,750 square kilometers (4,150 sq mi) to 33,500 square kilometers (12,900 sq mi). It contains over 500 species of scleractinian or stony corals, and at least 12 endemic coral species. The Coral Triangle contains 75% of
234-421: Is dubbed as "the center of the center of marine fish biodiversity". Within its territory, thirty-three endemic species of fish have been identified, including the blue-spotted angelfish ( Chaetodontoplus caeruleopunctatus ) and the sea catfish ( Arius manillensis ). The Philippine marine territory has also become a breeding and feeding ground for endangered marine species, such as the whale shark ( Rhincodon typus ),
273-539: Is integral with southern Luzon. Any suggestion that Northern Luzon is not part of the Philippine Mobile Belt is not borne out by the detailed fault mapping of Pinet and Stephan (1989), and others. A common tectonic plate illustration for the Philippines is incorrect in this regard. The composition of the Philippine Mobile Belt is generally interpreted as a collage of a large variety of blocks or terrane of diverse origin amalgamated before collision with
312-537: Is sometimes also considered a marginal sea of the Atlantic. (coast-wise from north to south) (from east to west) While all other seas in the world are defined at least in part by land boundaries, there is only one sea which is defined only by ocean currents: Entities called "seas" which are not divisions of the World Ocean are not included in this list. Excluded are: Philippine Mobile Belt In
351-655: The 1st Mobile Fleet of the Imperial Japanese Navy . Aside from the navy, aerial activity was also present in the Battle of the Philippine Sea, as hundreds of aircraft from both countries fired at each other. The Americans indisputably won, and nicknamed the aerial war the " Great Marianas Turkey Shoot " due to the number of Japanese aircraft shot down. Japan struggled to recover from the severe damages of its imperial navy and air strength suffered from
390-594: The Philippine Sea plate , including ophiolites in North Luzon, or continental crust from the Sunda plate . On top of which are Cretaceous to Quaternary magmatic arcs. These magmatic arcs are exposed in the western Central Cordillera , and the northern Sierra Madre . The Cagayan River Basin is an intra-arc rift . Subduction of Late Oligocene to Early Miocene South China sea oceanic crust occurs at
429-616: The Spratly Islands dispute in 2011, various Philippine government agencies started using the designation " West Philippine Sea " to refer to parts of the South China Sea . However, a PAGASA spokesperson said that the sea east of the Philippine archipelago will continue to be called the Philippine Sea. The Philippines depends on the Philippine Sea as one of the sources of its food, and for many people's livelihoods. In

#1732765943633468-644: The Sunda plate . They are not part of the Philippine Mobile Belt but are in collision with it. The Sulu Trench marks the boundary of the Sulu micro-block with the Sulu Sea basin and the Palawan micro-block. The inactive Palawan Trench marks the subduction boundary between the Palawan microblock and the Spratly Islands plateau of the South China Sea basin. The Palawan/Calamian arm was also known in 1981 as
507-520: The 577 known species of corals in coastal waters, including 19 seagrass species and 30 species of mangrove, both of which contribute nutrients to coral systems. The Philippines also consists of 20 percent of the shellfish globally. Sea turtles , sharks , moray eels , octopuses , and sea snakes , along with numerous species of fish such as tuna can commonly be observed. Additionally, the Philippine Sea serves as spawning ground for Japanese eel , tuna, and different whale species. The Philippine Sea
546-617: The Coral Triangle area, the Philippines harvests seaweeds, milkfish, shrimp, oyster, mussel, and live reef fish as aquaculture products. Fishermen catch many types of fish, including small pelagic, anchovy, sardine, mackerel, and tuna, among others. Recent scientific expeditions have found that the Benham Rise (also known as the Philippine Rise) in the Philippine Sea has a diverse marine ecosystem that attracts migratory commercial fish like tuna, marlin and mackerel. The Benham Rise
585-435: The Coral Triangle work to provide their people with technical assistance and other resources needed to promote conservation, sustainability, biodiversity, food security, sources of livelihood, and economic development. Climate change is affecting the coastal ecosystem found in the Coral Triangle. It is contributing to rising sea levels and ocean acidification , thus endangering marine animals like fish and turtles. This has

In the Central Philippines four principal blocks have been identified: Panay, Mindoro, Cebu and Bohol. In Mindanao six principal blocks have been identified: Pacific Cordillera, Surigao, Pujada peninsular, Central Cordillera of Mindanao, Daguma range and Zamboanga. In Luzon,
702-669: The Manila Trench. In Visayas, oldest known magmatic rocks in the Philippines are found in Cebu Island, where dioritic rocks have been dated at Lower Cretaceous (Walther and others, 1981), similar rocks have been recognized in neighboring Bohol Island. In Mindanao, interpretation of the age of these rocks is further complicated by their petrographic diversity. Sajona and others (1993) analyzed Pliocene-Pleistocene adakitic rocks in Zamboanga Peninsula and mention
741-516: The Manila Trench. Subduction of Eocene Philippine Sea oceanic crust occurs at the East Luzon Trough – Philippine Trench system. The strike-slip , left lateral fault , Philippine fault system is associated with the northward movement of the belt. The island of Luzon is bisected by the braided N–S trending Philippine fault system . Luzon is not bisected E-W, and illustrations showing anything similar are erroneous. Northern Luzon
780-537: The Middle Oligocene to Late Miocene age of the arc is well constrained stratigraphically as well as radiometrically. Most of the intrusive rocks are dioritic in composition, although alkali rocks also occur. In the Central Cordillera of Luzon, intrusive rocks include Paleogene rocks related to an ancient arc and Neogene intrusive and volcanic rocks related to eastward subduction from
