Skidaway Institute, in cooperation with the University of South Carolina, has installed
shore-based HF-radars along the Georgia, South Carolina and North Carolina coastline to
measure surface currents and waves across the continental shelf. Georgia radars on
St. Catherine's Island (since 2006) and Jekyll Island (since 2010) are long-range WERA
installations manufactured by Helzel MessTechnik of Germany, operating at a frequency
of 8.3 MHz, with daytime ranges of 220 km, reaching across the broad shelf and over the
shoreward flank of the Gulf Stream. Horizontal resolution is 3 km along radials,
with 2° azimuthal resolution (equivalent to 3.5 km at 100 km).
Where coverage from two installations overlap and their respective radials are
sufficiently non-parallel, vector velocities can be constructed at half-hourly
intervals (with 3 km grid spacing) from the radial velocities. A wealth of detail
is apparent in the surface current snapshot and zoomed image shown here.

Skidaway Institute radars were acquired through funding from the Georgia
Research Alliance, and are operated for research and observatory purposes with
combined funding from the National Science Foundation (NSF) and the National
Oceanic and Atmospheric Administration (NOAA). We are grateful to the St.
Catherine's Island Foundation and Villas by the Sea on Jekyll Island for their
