Drones yield an efficient method for measuring coastal currents

Accurate measurements of surface currents are crucial for coastal monitoring, rip current detection, and predicting the path of pollutants. Several methods exist to measure surface currents, some of which are costly and time-consuming. In a recent paper, researchers from Texas A&M University have compared three methods for measuring surface currents over large areas, identifying an ideal method that uses drones and wave-based current mapping.
