Survey of Submarine Volcanoes and Renewable Energy Potential in Sulu, Celebes, and Southern Philippine Seas
Scientists from the UP Marine Science Institute conducted a survey in December 2025 across the Sulu Sea, Celebes Sea, and southern Philippine Sea, focusing on submarine volcanoes, active faults, and renewable energy potential. The expedition revealed previously unmapped faults in Palawan and identified features conducive to unique marine life and potential bio-compounds. Additionally, findings indicated that the southern Philippine Sea has the necessary thermal conditions for Ocean Thermal Energy Conversion (OTEC), suggesting high potential for renewable energy and improved fisheries management.

In December 2025, a survey was conducted by the UP Marine Science Institute, alongside the University of California - Santa Cruz and Mindanao State University, in the Sulu Sea, Celebes Sea, and southern Philippine Sea. The expedition led by Dr.
Fernando Siringan identified submarine volcanoes and unmapped faults in Palawan, with a notable 10-meter displacement fault discovered. The southern Philippine Sea was highlighted for its potential for Ocean Thermal Energy Conversion (OTEC), with a measured temperature difference of 20°C at a depth of 200 meters, suitable for renewable energy. The research also emphasized the ecological significance of internal waves in nutrient mixing and fisheries productivity.
