TUBBATAHA REEF

Tubbataha Reef is an atoll coral reef located in the Sulu Sea of the Philippines. It is a marine sanctuary protected as Tubbataha Reef National Marine Park. It is nominated at the New 7 Wonders of Nature.

The word tubbataha is a combination of two Samal words: tubba and taha, which together means "a long reef exposed at low tide".

Tubbataha is located in the Sulu Sea, 98 nautical miles (181 km) southeast of Puerto Princesa City in the Palawan Province. The reef is made up of two coral atolls divided by an eight-kilometer (5 miles) wide channel. The South Atoll, the smaller of the two is five kilometers in length and three kilometers in width; while the North Atoll, the larger of the two is 16 kilometers (9.9 mi) long and five kilometers (3 miles) wide.(Knipp 22) Each reef has a single small islet that protrudes from the water. The atolls are separated by a deep channel 8 km (5.0 mi) wide.

There are no permanent inhabitants of the islets or reefs. Fishermen visit the area seasonally, establishing shelters on the islets. The park is visited by tourists, particularly divers. Trips to Tubbattaha from mid-March to mid-June are all vessel-based; the park is about twelve hours by boat from Puerto Princesa City. Tubbataha is considered as the best dive site in the Philippines and the diving dedicated ships that operate during the "Tubbataha Season" are usually booked years in advance especially during the Asian holidays of Easter and "Golden Week".

Tubbataha has become a popular site for seasoned sports divers because of its coral "walls" where the shallow coral reef abruptly ends giving way to great depths. These "walls" are not only wonderful diving spots but they are also wonderful habitats for many colonies of fish. There are giant trevally (jacks), hammerhead sharks, barracudas, manta rays, palm-sized Moorish idols, napoleon wrasse, parrotfish, and moray eels living in the sanctuary. There also have been reported sightings of whale sharks and tiger sharks. Tubbataha is even home to the hawksbill sea turtles (Eretmochelys imbricata) which are endangered species.

Over 1000 species inhabit in the reef; many are already considered as endangered. Animal species found include manta rays, lionfish, sea turtles, clownfish, and sharks.

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. (Knipp 22, 24) In June 2009 an outbreak of the crown-of-thorns starfish was observed, possibly affecting the ecological functioning of this relatively pristine coral reef.

Aside from being a marine sanctuary, Tubbataha is also renowned for being a bird sanctuary. A lighthouse islet, at the southern tip of the South Atoll, supports a large number of seabirds which nest there. Around the Tubbataha, there are tens of thousands of masked red-foot boobies, terns, and frigate birds resting during their annual migrations. To minimize any external intrusions, the Philippine Coast Guard maintains a small monitoring station on one of the many permanent sand bars.

The Tubbataha National Marine Park is open to live-aboard diving excursions between the months of April to June. It is in this period where the waves are most calm. As of March 2011, the park entrance fee is pegged at USD $75.00 or PHP 3,000.00. Due to global warming, it is advised that divers book their trips towards the middle or end of April as the waves are still strong and may cause problems for dive excursions and underwater visibility.

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.
