An HF-radar Test Deployment Amidst an ADCP Array on the West Florida Shelf
Digital Object Identifier (DOI)
For 11 days in January 2002, the Conrad Blucher Institute for Surveying and Science, Texas A&M University-Corpus Christi, in collaboration with the College of Marine Science, University of South Florida, deployed a pair of 25-MHz CODAR Ocean Systems HF-radars on the West Florida Shelf over an array of six acoustic Doppler current profilers. The radar footprint had a maximum range of 60 km offshore, and it included mooring locations between the 10 m to 30 m isobaths. We examine, using a variety of metrics, the correlation between the surface currents measured remotely by the HF-radar and the subsurface currents measured by the ADCPs, which were either bottom- or surface buoy-mounted. Qualitative comparisons are generally good for this inner-shelf environment where the wind-driven current magnitudes were less than about 40 cm/s. The scalar regression analysis shows correlation coefficients (R) of 0.8 to 0.9 for the alongshelf components but 0.6 or less for the cross-shelf components. Complex vector correlation produces correlation values of 0.76 to 0.90 and a consistently clockwise veering from the radar-measured currents to the ADCP-measured ones ranging from 1.3 to 5.2 . The alongshelf surface currents measured by the radar are about 30% larger than those of the ADCPs measured 2 to 3 m below the surface according to standard deviations and linear regression slopes.
