1. Success Stories – Making a Difference Optimizing HF Radar for SAR using USCG Surface Drifters Art Allen U.S. Coast Guard Josh Kohut, Scott Glenn Rutgers University and the Mid-Atlantic Regional Coastal Ocean Observing System

2. USCG Area of Responsibility

3. Mid-Atlantic is the Most Urbanized Coast in the Unites States Puerto Rico has many similarities

5. CG Wide 1) 3 searches / day = ~ 1000 / yr 2) 3 persons lost / day = ~ 1000 / yr 3) Costs $10k/hr to search $10k/hr x ~1000 x ~ 3 hr = ~ $30M 4) Value of Statistical Life = $3M 1000 x $3M = ~ $3B

6. CG Wide 1) Assume 100 persons involved / yr with sub-optimal search areas 2) Assume 22% POS now “typical” 3) 22 save/100 vs. 48/100 vs. 67/100 4) Save 26 to 45 additional persons / yr ($ 78M – $135M VSL)

7. Search & Rescue Problem Create a SAR case when alerted Gather data, estimate uncertainties Use model to determine search area Estimate resource availability and capability Plan the next search Promulgate the search plan Perform the search plan Evaluate the completed search Repeat above until survivors are found and rescued

8. Compact CODAR HF Radars Receive Antenna Transmit Antenna 25 MHz and 13 MHz 5 MHz
