Radar returns from the ocean surface have been observed since the earliest days of radar. They were characterized as "clutter" because they often obscured targets, such as ships or aircraft. However, ...
Mapping Surface Currents in Monterey Bay With CODAR-Type HF Radar
Mapping Surface Currents Monterey Bay CODAR-Type HF Radar

High-frequency (HF) radar measurements have been employed around Monterey Bay, CA, to measure ocean surface currents since February 1992. The first array consisted of two older-generation CODAR instru...
The Coastal Jet:Observations of Surface Currents Over the Oregon Continental Shelf From HF Radar

The ocean circulation over the Oregon shelf during spring and summer is dominated by the effects of coastal upwelling. Equatorward winds drive an offshore Ekman transport in the surface layer, which p...

Surface current observations from high-frequency (HF) radar have revealed that not only are the low-frequency and tidal currents resolved by the measurement, higher-frequency motions are also containe...
Larval Transport and Coastal Upwelling: An Application of HF Radar in Ecological Research
Larval Transport Coastal Upwelling HF Radar Ecological Research

For many marine fish and invertebrate species, near-surface currents strongly affect the likelihood of surviving as a planktonic larva and arriving at a suitable location, say, a rocky coastline, a ke...
HF radars are a unique and powerful tool for measuring surface currents. They provide an unparalleled window into the spatial variations of near-surface currents. But oceanographers who are more accus...

Oceanographic research using HF radar techniques started in Germany in 1980 by adopting NOAA's CODAR (Coastal Ocean Dynamics Applications Radar), which has originally been introduced by Barrick et al....
Nearshore and inner shelf dynamics are forced principally by radiation stress gradients induced by shoaling and breaking waves. Waves in shallow water refract due varying bottom topography. Thus the w...
Besides the measurement of ocean surface currents, high-frequency (HF) radar has also been demonstrated to be effective at measuring the wind direction at scales on the order of one to several kilomet...
