Wave Heights And Currents in the Florida Straits (WHARF)

SECOORA HF Radar Waves Project Update

In April 2014, Dr. Nick Shay, SECOORA PI from the University of Miami (UM) Rosenstiel School of Marine & Atmospheric Science, his graduate student Matthew Archer and the crew onboard the R/V Walton Smith deployed a subsurface mooring in the Straits of Florida.

The mooring is equipped with a NortekUSA acoustic wave and current profiler (AWAC) instrument1. Matthew was a recipient of NortekUSA's Student Equipment Award and was awarded the AWAC to perform the experiment. The AWAC profiler is located at 25.93N and 79.88W in the UM maintained High Frequency (HF) radar footprint (between Dania Beach and Virginia Keys stations) in the Straits of Florida.

It will obtain wave data in order to evaluate the WERA HFR derived significant wave height (SWH) measurements.The AWAC is expected to provide a three month time series. The measurements obtained during the spring and summer transition period will allow proper calibration of the HF Radar wave measurement algorithm.  The data from AWAC, coupled with the HF radar, satellite sea surface temperature and local wind velocity observations will provide a comprehensive four-dimensional (x, y, z, t) dataset to resolve the flow-field evolution at the shelf-break.1The intent is to deliver a quality control index for the extraction of real-time SWH fields for use by the National Weather Service forecasters to evaluate the marine forecasts in the Florida Straits.2  For more information, please contact Nick Shay at
