High-resolution ocean velocity data has become readily available since the introduction of very high frequency (VHF) radar technology. The vast amount of data generated so far, however, remains largely unused in environmental prediction. In this paper, we use VHF data of the Florida coastline to locate Lagrangian coherent structures (LCS) hidden in ocean surface currents. Such structures govern the spread of organic contaminants and passive drifters that stay confined to the ocean surface. We use the Lagrangian structures in a real-time pollution release scheme that reduces the effect of industrial contamination on the coastal environment.

The authors are grateful to the Office of Naval Research and particularly to Manuel Fiadero for his support and advice. This research was funded and supported by ONR grants N00014-97-1-0071 and N00014-95-0257. G.H. was also supported by by AFOSR Grant F49620-03-1-0200 and NSF Grant DMS-04-04845. The authors also want to thank Shawn Shadden and Jan VanWalke for their remarks and suggestion to maintain and improve the software package MANGEN and Katharine Ratnoff for providing them with her editorial skills. The acquisition of the OSCR data by the University of Miami was supported by the Office of Naval Research (N00014-98-1-0818, LKS). Tom Cook, Brian Haus and Jorge Martinez kept the OSCR up and running for the experiments. Jose Vasquez of the City of Hollywood Beach and Jim Davis of Broward County Parks and Recreation kindly permitted us to the property on the beach in Hollywood. June Carpenter allowed us access to her beach house for OSCR operations. Renate Skinner and Sid Leve permitted us to use the beach at the John U. Lloyd State Park. Bill Venezia of the US Navy’s South Florida Test Facility provided us with real estate and electricity to conduct our operations.
