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.
