A new direction‐finding system is capable of tracking, from coastal stations, the drift of drogues more than 100 km from the shoreline. Frequency‐dependent transmitters on light, inexpensive drogues permit as many as fifteen widespread drogues to be monitored quasi‐simultaneously, enabling researchers to obtain mesoscale synoptic data at reasonable cost for the first time. Field tests on a moored drogue in Chesapeake Bay and on free‐drifting drogues at sea off Barbados show the system to be reliable and accurate.
