6. 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: HYCOM = 36,000 km2
SAROPS 96-Hour Search Area: HF Radar = 12,000 km2

7. 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.
Hate Downwelling

8. Water Quality – Nearshore Currents
Alongshore Current
Nearshore currents derived from single site radial currents track the movement of water quality constituents within 3 km of the beach.

13. Physics-based numerical computer model that provided preliminary estimates of the annual average wind using their proprietary MesoMap system.

14. U'c(x,y,t) = slope(x,y)*W'(t)
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)
