NASA brought sea level science to the public through an outreach event that reached over 1,000 visitors at the University of Georgia Aquarium on Skidaway Island during World Ocean Day on June 6, 2026.
The agency demonstrated its satellite-based research that tracks ocean heights and coastal changes across the planet. NASA operates a constellation of instruments dedicated to monitoring sea levels, including the Jason series of altimeter missions and the Surface Water and Ocean Topography satellite, known as SWOT. These spacecraft measure ocean surface height to within centimeters, revealing patterns invisible to ground observers.
Rising sea levels pose direct threats to coastal communities worldwide. NASA's measurements document that oceans have risen approximately 3.4 millimeters per year over the past three decades, with rates accelerating in recent years. This data proves essential for urban planners, climate scientists, and policymakers who work to understand coastal flooding risks and plan adaptation strategies.
The University of Georgia Aquarium location provided an ideal venue for this outreach. Skidaway Island sits on Georgia's coast, where sea level rise already affects infrastructure and saltwater intrusion into freshwater aquifers. Museum visitors encountered interactive displays explaining how NASA satellites track water temperature, currents, and height variations. Educators demonstrated how ocean data connects to climate change, ecosystem health, and human communities.
NASA's sea level program integrates data from multiple sources. The Jason-3 mission, operated jointly with the European Organization for the Exploitation of Meteorological Satellites, provides continuous records spanning decades. The newer SWOT mission, launched in 2022, maps water bodies at unprecedented resolution, capturing details of rivers, lakes, and coastal zones. These measurements feed into climate models that predict future sea level scenarios under different emissions pathways.
World Ocean Day, observed annually on June 8, emphasizes ocean conservation and sustainable practices. NASA's participation connects space technology to terrestrial challenges. Visitors learned how satellites launched into orbit become tools for protecting coastal ecosystems and informing climate adaptation.
The outreach event served multiple purposes. It demonstrated NASA's commitment to science communication beyond peer-reviewed journals and scientific conferences. It engaged students, teachers, and families with hands-on explanations of how orbital sensors measure planetary changes. It highlighted the relevance of space-based Earth observation to everyday life in coastal regions.
These public engagement efforts build scientific literacy around climate and ocean systems. When visitors understand how NASA tracks rising seas through satellite technology, they grasp both the scale of global challenges and the tools available to address them. The event reinforced that space exploration serves not only distant scientific goals but also immediate practical needs on Earth.
NASA continues expanding its Earth observation network. The Sentinel missions operated by the European Space Agency, alongside NASA initiatives, create a global monitoring system. Together, these spacecraft provide the data transparency necessary for communities to make informed decisions about coastal development, disaster preparedness, and climate resilience.
