2. ________________________________________ Outline Case Study of the Ehime Maru (Oahu, Hawaii) Data Demonstration of COGOW Potential Users Summary

3. ________________________________________ Ehime Maru vs USS Greeneville 9 February 2001 USS Greeneville (Los Angeles class submarine) collided with a Japanese training and fishing vessel Ehime Maru Ehime Maru sank in ~ 600m of water, ~17km south of Diamond Head (Oahu, Hawaii) 26 of 35 crew members were rescued 9 remaining crew members were assumed trapped inside the vessel

4. ________________________________________ Recovery of Missing Crewmembers Under mounting int’l pressure the US Navy agreed to attempt to recover the bodies A Navy environmental assessment concluded that moving Ehima Maru to shallower water wouldn’t result in sig. environmental impacts thus the project was approved

5. ________________________________________ Environmental Concerns There was still concern that during relocation a release of contaminants (diesel fuel & lubricating oil) could occur –Beach Contamination –Marine Mammals, Migratory Birds, Sea Turtles, etc. DLNR, NMFS, USFW & NOAA were all involved in the recovery plan

6. ________________________________________ NOAA/HAZMAT’s Mandate To determine, through the use of oil-plume models, the optimal sea state and wind conditions necessary to avoid beach contamination Models: –assumed ave. wind speed of 10 knots (~5 m.s -1 ) –full range of wind directions –ebb & flood tidal conditions East-Northeast winds would likely contaminate beaches during both tidal conditions North-Northeast winds would likely push contaminants out to sea

8. ________________________________________ QuikSCAT SeaWinds scatterometer launched on 19 June 1999 onboard the QuikSCAT satellite SeaWinds is an active microwave radar Measures vector winds (25x25 km) using electromagnetic backscatter from a wind roughened ocean surface Accuracy: 1.5 m.s -1 and  17 o (equivalent to the accuracy of well calibrated buoys) 90% daily coverage of Earth's surface 3-Day averaged data & monthly averaged data

12. ________________________________________ Summary COGOW was not available during this incident No historical wind data was available for the collision site NOAA/HAZMAT would have used it in a planning capacity Thousands of sunken vessels in and around coastal waters This tool will be very effective in assisting response and contingency planners.
