science π Satellites map tiny tide shifts across coastlines
Scientists found a new way to track localized tidal changes using over 40 years of satellite images. Researchers from the Technical University of Munich analyzed Landsat photos across the Pacific Rim between 1984 and 2026. This method mapped tide variations at 100-meter intervals, revealing fine-scale coastal behavior missed by traditional gauges. The study confirmed that tides can vary substantially over very short distances, impacting coastal flooding risks. These advanced methods could lead to much more precise, localized tide forecasts in the future. π
