  1. GCOOS HF Radar Gap AnalysisVersion 1.0, 27 June 2008 • Key Authors • Stephan Howden, USM • Nick Shay, UM • Ann Jochens, TAMU • Consulted with • GCOOS-RA Board of Directors • Harvey Seim, SECOORA All RA HFR Gap Analyses available at http://www.usnfra.org/committees.html

  2. GCOOS Network of HF Radar Observing Systems for Surface Currents and Waves • Continue operations of the existing operational High Frequency Radar (HFR) network (6 units) in the GCOOS region; • Determine the status of units that once were operational and whether such units can be incorporated into the GCOOS HFR network; • Develop a more complete understanding of quality control and quality assurance issues for different HFR systems and how to ensure compatibility and ability to combine measurements from different HFR systems; and • Develop for the Gulf a plan for choosing particular HFR station types, operating frequencies, locations, and infrastructure plans for each site.

  3. Gaps • Long-Range (>75 km range) HFR: • No operational long-range HFR stations from Brownsville, TX, to Gulfport, MS (approximately 750 mi). • USM 's long-range HFR stations cover the region from Gulfport, MS, to Destin, FL. • Another gap exists from Destin, FL, to Redington Shores, FL (approximately 450 mi). • USF's long-range HFR stations cover the region from Redington Shores to Naples, FL. • The region between Naples, FL, down to the Keys (~ 250 mi) and over into the Miami, FL, area is the last GCOOS gap. • Short- and Medium-Range HFR: There is insufficient funding to cover the entire Gulf Coast with these radars; only selected areas.

  4. Priorities for HFR Network • Cover the US Gulf Coast by long-distance (>75 km) radar systems with overlapping coverage sufficient to estimate 2-D surface current fields in these regions. • Install HFR equipment that can also measure directional wave information where affordable • Nest higher frequency radar systems within selected regions for higher spatial and temporal resolution systems is to cover regions with substantial ship and boat traffic. • 6 NOAA Physical Oceanographic Real-Time System (PORTS) • Houston/Galveston, TX, • Sabine Neches, TX, • Gulfport, MS, • Pascagoula, MS, • Tampa Bay, FL • Southwest Pass of the Mississippi River • Corpus Christi, TX • Miami, FL • Conduct pilot project to determine how to combine data from different HF radars into a Gulf coastal surface current map
