U.S. Coast Guard: Search And Rescue Optimal Planning System SAROPS Mid-Atlantic Operational Data Flow to SAROPS SAROPS User Interface SAROPS 96-Hour Search Area:HF Radar= 12,000 km2 SAROPS 96-Hour Search Area: HYCOM = 36,000 km2
Ecological Decision Support – Fisheries Divergent + Convergent Like Upwelling Our Approach: Develop statistical models using bottom trawl surveys and MARACOOS 3-D data to predict species distribution based on observed or forecasted MARACOOS 3-D fields.

Future Medium Range Network13 MHz Range ~ 80 km Resolution 2 km
13 MHz Tx/Rx Antenna Single antenna at 13 MHz Transmit and Receive Radial whips no longer needed Possible to install with no guy wires and small base
Physics-based numerical computer model that provided preliminary estimates of the annual average wind using their proprietary MesoMap system.
HF Radar Derived Linear Wind Model Current Transient [U'] (cm/s) Wind Transient [W'] (cm/s) • Rotate wind vectors according to complex correlation • Calculate the slope and intercept of best fit line U'c(x,y,t) = slope(x,y)*W'(t)
Ecological baseline studies of offshore wind power already performed • Avian species • Fisheries • Marine Mammals • Sea turtles • This project will perform physical baseline study
U.S. National HF Radar Network Data Flow Since 2007 2004 Plan Today’s Coverage 131 Radars
Conclusions • Rutgers is measuring the ocean 24/7 • HF Radar network can provide validation of atmospheric models and spatial maps of wind resource off NJ • Lessons learned from this project can be exported to the nation and the world
