Tubbataha Reef

The natural park is located near the middle of Sulu Sea, southeast of Puerto Princesa, covering a total of . The smaller Jessie Beazley Reef is located about north of the two atolls. ==Geology==

Tubbataha Reef is situated on Cagayan Ridge, an extinct underwater volcano and an island arc during the Miocene. Being a true atoll structure, it is believed that the atolls of Tubbataha were formed as fringing reefs and volcanic islands. This follows the classical Charles Darwin's theory that atolls are formed around an existing volcanic island. When the volcanoes became extinct and the islands subsided over a long time, only the corals remained which then continuously grew towards the surface. The staircase-like slopes of the modern reef are now a product of the fluctuating sea levels as the crust under Cagayan Ridge cools and subsides. ==History==

Etymology The word tubbataha is a combination of two Sama–Bajau words: tubba and taha, which together means "a long reef exposed at low tide". Historically, Sama-Bajau peoples, who have a nomadic lifestyle, visit the reef from time to time. Although people from the islands of Cagayancillo are frequent visitors of the reef. They used the native vessel banka to sail and fish on "Gusong", their local name for the Tubbataha. Protection in the middle of the Sulu Sea Tubbataha's isolation, located in the middle of the Sulu Sea far from inhabitants of the nearest populated islands, had preserved its marine resources from over-exploitation over the years. The two islets in Tubbataha have no source of freshwater thus preventing habitation. In the 1980s, fishermen reaching Tubbataha increased in numbers with the advent in motorized bangkas, instead of the traditional sailboats. Fish had declined in other fishing grounds because of overfishing and soon Tubbataha became a fishing destination because of its abundant marine life. Many fishermen used destructive fishing techniques like cyanide and dynamite fishing to maximize their catch. In the early years of law enforcement by the Presidential Task Force, the rangers were housed in a simple canvas tent. In 1996 a wooden structure was built but shifting sand soon rendered its foundations unstable. At present, the marine park rangers are housed in a styrofoam-reinforced concrete structure on the Southeast Islet on Tubbatha's North Atoll. The National Marine Park was enlarged in 2006 to include the Jessie Beazley Reef. President Gloria Macapagal Arroyo signed Proclamation no. 1126 on August 23, which increased the boundaries of the park by 200% to . The national park was also reclassified as a natural park. It is guarded by armed rangers 24 hours/7 days a week. On July 25, 2017, the Tubbataha Reef was designated as a Particularly Sensitive Sea Area (PSSA)—and an "area to be avoided"—by the International Maritime Organization. ==Management==

Although the reefs are geographically part of the island municipality of Cagayancillo, Palawan, located roughly to the northeast of the reef, ==Ecology==

Over 1000 species of marine life inhabit the reef with many considered endangered. Animal species found include manta rays, lionfish, sea turtles, clownfish, and sharks. Tubbataha has become a popular site for seasoned sport divers because of its coral "walls" where the shallow coral reef abruptly ends giving way to great depths. These "walls" are also habitats for many colonies of fish. Giant trevally (jacks), hammerhead sharks, barracudas, manta rays, palm-sized Moorish idols, napoleon wrasse, parrotfish, and moray eels live in the sanctuary. There also have been reported sightings of whale sharks and tiger sharks. Tubbataha is even home to cetaceans and hawksbill sea turtles (Eretmochelys imbricata) which are critically endangered species. Being a UNESCO World Heritage site, all living organisms are protected. Vivid corals cover more than two-thirds of the area and the waters around the reef are places of refuge for numerous marine lives. The seemingly diverse ecosystem of this sanctuary rivals the Great Barrier Reef – having 350 coral species and 500 fish species. In June 2009 an outbreak of the crown-of-thorns starfish was observed, possibly affecting the ecological functioning of this relatively pristine coral reef.

Tubbataha is considered one of the best dive sites in the world according to CNN Travel. Trips to Tubbataha National Marine Park from Puerto Princesa operate during the diving season from mid-March to mid-June, the period where the waves are calmest, skies clear and water visibility of about . The park is about ten hours by boat from the city. All trips are vessel-based or "liveaboard" as there are no accommodation facilities. Visitors stay on the yacht/boat throughout their stay in the park. During the diving season, ships dedicated for diving are usually booked years in advance especially during Easter and the Asian holidays called "Golden Week". As of March 2011, the park entrance fee for individuals is pegged at US$75.00 or PHP3,000.00. In September 2010, Palawan governor Abraham Kahlil Mitra announced that local residents of Palawan province can enter the Tubbataha Reef without paying the conservation fee. Divers are advised to book their trips towards the middle or end of April as calm seas from April to June have a short window. Although the sand bars around Tubbataha are considered off limits to human beings, tourists are allowed to set foot at the Ranger Station where they can purchase souvenirs and tour the facility. ₱1000 bill- The park is featured on the reverse side of the 2010 series of the Philippine one thousand peso bill. ==Ship grounding incidents==

YMS 340 In October 1945, the auxiliary motor minesweeper YMS 340 ran hard aground on Tubbataha Reef causing minor damage to the reef. Te USS Leland E. Thomas (DE 420) was unable to pull YMS 340 from the reef and radioed for assistance. The USS Gillette DE 681 arrived and YMS 340 was towed off the reef and escorted to Manila by the USS Gillette and the US Navy Tug Vireo. Rainbow Warrior On October 31, 2005, the Greenpeace ship Rainbow Warrior ran aground on Tubbataha Reef accidentally damaging approximately of reef for which they paid a fine of about $7,000. Greenpeace blamed the accident on inaccurate charts provided by the Philippine government. The BBC quoted Greenpeace official Red Constantino as saying "The chart indicated we were a mile and a half" from the coral reef when the ship ran aground. The U.S. Government initially blamed the grounding on faulty maps. The U.S. Navy concluded that towing the ship off the reef would cause more damage and decided to dismantle the ship in place. On March 30, the last section of the ship was removed from the reef. On April 8, 2013, the U.S. Navy turned over digital navigation charts and other relevant documents and data of the Guardian to the Philippine Maritime Casualty Investigating Team (MCIT) and responded to various technical and substantive queries. The MCIT conducted its own independent investigation and made recommendations on how to avoid such incidents in the future. The U.S. Federal Government was assessed a fine of 24,000 Philippine pesos (about US$600) per square meter. On January 20, 2015, the United States Government paid to the Philippine government a total of 87 million Philippine pesos, or US$1.97 million – 59 million Philippine pesos for the damage and another 29 million pesos to reimburse for services provided by the Philippine Coast Guard.

The fishing vessel had 12 crew members and was suspected of illegal fishing. On board, what was found instead were 400 boxes of frozen pangolins of unknown origin. ==See also==
