science 🛰️ Satellite pics reveal huge beach-scale tide changes
New research using decades of satellite images shows tidal levels can vary almost a meter across a single bay. Researchers from Technische Universität München and the University of Oxford developed a technique to measure tides every 100 meters along the coast. Analyzing data from over 40 years on the Pacific Ocean, they found significant local differences in tidal height. This proves that distant models might miss crucial conditions at specific beaches for coastal safety. The method could greatly improve localized tide forecasts globally. 🌊
