📢 NEW EPISODE 📢
In this episode, we talk with Mary Rose P. Gabuyo about her study on using low-cost fish finders — the kind used for recreational sport fishing — to detect and map submarine groundwater discharge (SGD) in coastal waters. SGD refers to all direct discharge of subsurface fluids across the seafloor, including fresh groundwater, recirculated seawater, and gases like CO₂ and methane. Despite its ecological significance, mapping SGD remains a challenge because conventional methods are costly, tedious, and require specialized equipment. This study tested whether recreational-grade echosounders could do the job — and they did.

What is it like to conduct science in the country's westernmost inhabited island? In celebration of the International Day of Biological Diversity and Philippine Month of the Ocean, UP Marine Science Institute is launching "Pag-asa Island: A Hidden Pearl of Biodiversity" — a new webpage featuring the marine life and research done in the Kalayaan Island Group over the years.

Our laboratory proudly announces the defense of Jamela Jirah Clemente and her master's thesis entitled, "Quantifying the erosion rates of siliciclastic, carbonate and mixed siliciclastic carbonate coasts of northern La Union using multi-temporal satellite imagery". Her research investigates how reef platforms and sediment composition influence coastal erosion along northern La Union’s shoreline. This tackles our current understanding of nature-based coastal protection in the Philippines.

The defense seminar will be held on 29 May 2026, 10:00 am at the UP Marine Science Institute AVR, and via Zoom platform. Kindly send us a message for the link
