2. Katie Kirk Michael Walsh Jupiter Foundation – Acoustic Localization Supervised by Beth Goodwin

3. Meet The Guys…

4. Wave Glider Autonomous vehicle, wave & solar powered

5. Timeline First Week – Boat Ops – Getting acclimated & Oriented Second Week – Localizations & Getting Data Third Week – Displays and Interpretation of data Final Week – Polishing up & Boat ops

6. Proof of Concept - Never been done before! -Advantage of this method: low-cost, non- invasive, and autonomous. Shore Station Sightings for ground proof - Recorded whale surfacings and environmental variables

7. Localization Process Look for curvature in sound signal Log it Have XBAT compute the location of the sound source – Find sound source on all three channels – Uses the time delay of signal reaching hydrophones

8. Spectogram

9. Post Localization Processing Matlab – Master Function Export_Files Takes info from xBat – Function within - LinearArrayDisplayLocation Processes the exported files Subfunctions – ReflectLocation, FilteredMatrix Creates figures, associated data files

10. EXPORT_FILES

11. Original XBAT Localizations Has Ambiguity – Appears mirrored over the black line. Not very useful!

12. ReflectLocation2 Function ReflectLocation1 used visual confirmation of points needing reflection ReflectLocation2 uses a line of reflection which makes it more precise

13. FilteredMatrix Function

14. FilteredMatrix Display

15. Reflected, Filtered, Averaged
