A new telemetry system measures the direction and magnitude of the forces imposed on intertidal organisms by individual breaking waves. Cast epoxy replicas of organisms are mounted on three transducers embedded in an exposed rock surface. Force data are encoded as a frequency‐modulated audio signal and transmitted as an FM radio signal a sufficient distance so that the receiving and recording apparatus is safely away from the wave‐swept shore. The system measures forces in the range of 0.1–10 N, but can be scaled to fit a variety of applications. The apparatus is simple to build and inexpensive.
