Satellite shoreline images expose fine-scale tide variations within bays
Researchers have developed a method using decades of Landsat satellite photos to estimate tide levels along coastlines at 100-meter intervals. The technique reveals that tidal heights can differ by nearly a meter within a single bay, offering far more local detail than traditional gauges or radar satellites. This could improve flood risk modeling and navigation planning.
