MANILA: A team of Filipino scientists last week sailed to the Philippine Rise, situated on the eastern side of the country, to explore unknown treasures in the resource-rich undersea region.
A ceremony was held on May 15 aboard the Philippine Navy’s amphibious landing dock vessel BRP Davao Del Sur.
President Rodrigo Duterte led the send-off of the team, which will undertake the Coordinated National Marine Scientific Research Initiatives and Related Activities (CONMIRA).
Duterte was supposed to visit the Philippine Rise and ride a jet ski around the area, but instead he led a program aboard the BRP Davao Del Sur while it was docked in Casiguran Bay in Aurora province.
The activity was to commemorate the awarding of the Benham Rise to the Philippines by a UN tribunal.
The UN approved the Philippines’ claim to the area in April 2012. On May 16, 2017, Duterte signed an order renaming it the Philippine Rise.
He also signed a proclamation formally declaring parts of the undersea feature a marine resource reserve.
After Duterte left, a flotilla with the BRP Davao Del Sur sailed to the Philippine Rise. The flotilla included eight other ships.
A flag-raising ceremony was held on May 16 aboard the BRP Davao Del Sur, simultaneous with the laying of an underwater flag marker at the Benham Bank, the shallowest point in the Philippine Rise.
Gil Jacinto of the Marine Science Institute at the University of the Philippines told Arab News that the two-day event raises awareness among government agencies and the Filipino people “about this part of the country that we have sovereign rights over,” and “the needed work by the scientific community.”
He lauded Duterte’s commitment to support marine science research, adding that the Benham Bank contains a “very good coral cover” and “almost wall-to-wall carpeted corals.”
Jacinto said: “Studies related to tuna fisheries, biology and migration patterns can also be pursued.”
Oceanographers want to understand physical processes, such as major currents and the movement of water from the Pacific to the eastern side of Luzon island all the way to Mindanao island.
“Our understanding of physical processes and features of the Pacific side can perhaps be useful in some of the models that project the trajectory and intensity of typhoons,” said Jacinto.
“That’s of interest and perhaps of benefit not just to the Philippines but also in the West Philippine Sea and South China Sea region.”
Scientists will also be looking at prospects for energy sources in the area, and the possibility of obtaining compounds on marine organisms that may benefit the medical and pharmaceutical fields.
“One thing I’m very glad about for this event is this part of the country is now in the mindsets of our people,” said Jacinto. “There’s so much that can be done here.”
The scientists opted to sail to the Philippine Rise instead of the West Philippine Sea because they can work in the area “relatively unimpeded,” whereas in the West Philippine Sea there are security issues due to maritime border disputes, he added.
The Philippine Rise is a 13-million-hectare underwater plateau located some 250 km east of northern Luzon.
Its original name came from American geologist Andrew Benham, who surveyed the area in the 1930s.
The Benham Bank exhibits a rich marine biodiversity. Its reefscapes contain corals, algae, sponges and Halimeda, which sustain a variety of fish.
Results of exploratory fishing suggest that the Philippine Rise yields the highest catch rate of tuna species compared with other areas of the country.
The Philippine Rise may also contain seabed resources such as cobalt-rich ferromanganese crusts, and hydrothermal polymetallic sulphides that contain minerals used in the aerospace industry.
Experts have revealed vast deposits of methane hydrate in the area, believed to be a larger hydrocarbon resource than the world’s oil, gas and coal resources combined.
