The Gulf of America is experiencing accelerated sea-level rise driven by ocean dynamics, vertical land motion and warming waters, intensifying flood risks for coastal communities – especially rural, under-resourced areas with limited planning capacity. A new four-year, $900,000 grant supports high-resolution modeling, machine learning and community engagement to deliver precise local projections, deploy water sensors and build an accessible AI platform, equipping communities with actionable forecasts to strengthen resilience and long-term adaptation.
