Surface Currents - HF Radar

The National HF Radar Network shows results for all US HF Radar sites through Google Maps.

Also NOAA HF Radar site provides HF radar results.

Scattering of high frequency (12 MHz) radio (HFR) emissions by ocean waves is used to produce maps of surface ocean currents. HFR current maps for the Mona Passage are made possible through support from the Department of Homeland Security to the Center for Secure and Resilient Maritime Commerce and Coastal Environments (CSR). Technical and administrative support to CSR is provided locally by CariCOOS in the operation of 2 transmit/receive antenna pairs located at Club Deportivo del Oeste in Cabo Rojo and the Puerto Rico Police FURA station on Añasco beach. Power output of the antennas is about 40 watt; the equivalent of one low power incandescent light bulb.
