Sea Surface Currents and Waves

High-frequency (HF) radar uses radio-wave backscatter to map surface currents over wide swaths of the coastal ocean. These are commonly referred to as HF Radar Instruments and take advantage of the propagation of radio waves over large distances out and back across the surface of the conducting sea water, and they have resonant interactions with ocean surface waves (i.e., the ones that can make people seasick). Back at the shoreline, a measurement of the frequency offset (i.e., Doppler shift) of the reflected radio waves provides a remotely sensed measurement of the speed of the ocean waves and surface currents. For more information see Detailed sensor description >>

The Bodega Marine Laboratory operates five HF Radar stations located in Bodega Bay, Point Reyes, Salt Point, and Point Arena, CA.
