The 51st Department Seminar of the UP Department of Geodetic Engineering was held on March 6, 2025, from 10:00 AM to 12:00 NN at the GE Theater and via Zoom. The event spotlighted critical insights from the research of Dr. Rosalie B. Reyes, presented by Instructor Roel T. Bahia, on the varying mean sea level and sea level rise in the Philippines.

Instr. Bahia discussed key findings from the CSLR-Phil Project, with particular emphasis on sea level discrepancies between Manila and Legaspi, Albay. He elaborated on the scientific data regarding sea level changes, their implications for coastal areas, and the importance of establishing a unified vertical datum across the country—a step vital for consistent elevation measurements and effective climate adaptation planning.

The seminar began with the national anthem and an invocation, followed by opening remarks from Dr. Alexis Richard C. Claridades. The event drew a diverse audience of 60 onsite participants—students, faculty, and industry partners—and 21 online attendees from key government agencies like NAMRIA and PHIVOLCS.

After the presentation, Dr. Claridades awarded a certificate of appreciation to Instr. Bahia. The seminar concluded with closing remarks from Asst. Prof. Luis Carlos S. Mabaquiao and a group photo session.

The discussion highlighted the pressing impact of climate change on coastal communities and underscored the urgency for accurate sea level monitoring and standardization. The event reinforced the academic and collaborative efforts being made toward achieving sustainable and resilient development.

Special thanks were given to Dr. Rosalie B. Reyes for her leadership in the CSLR-Phil Project and her substantial contributions to this important research.
