NIGS Instructor, Ms. Elisha Maglalang, who is currently pursuing her PhD at Cardiff University, UK, is the latest guest of the popular Behind The Science Podcast. She talks about her research on the existence of gas hydrates in the seabed west of Luzon, as well as her journey in geoscience research in the Philippines and abroad as a young geoscientist.
📢 NEW EPISODE 📢
In this episode, we talk with Elisha Jane M. Maglalang about her study on the possible occurrence of gas hydrates in offshore western Luzon — the first of its kind in the Philippines. Gas hydrates are ice-like substances that trap methane gas within their molecular structure and form naturally on the seafloor under high pressure and low temperature. They are of significant interest both as a potential alternative energy resource and as a geologic hazard. Their dissociation can release large amounts of methane into the atmosphere and trigger underwater landslides. By reinterpreting existing multi-channel seismic reflection data from the Manila Trench, the study identified bottom simulating reflectors, which is the primary seismic signature of gas hydrate presence, across a total area of approximately 15,400 km² in the Manila Trench forearc region.
