More transients and localization

Prevost Harbor to Mitchell Bay
At 09:30 hours Val did a lecture on localization.  Right after the lecture we did an exercise on localization involving the ‘clangs’ at the OrcaSound and Lime Kiln hydorphone’s (there are some msyterious clanging/clinking sounds that have been heard intermitently on the hydrophones this winter/spring).  Our results indicated that the hyperbola leads to Discovery Island / Beaumont Shoals.  This is just an estimate from where the sound source may be.
Then at 13:25 hours we had an encounter with three transients whales.  We have IDed them as T10,T10B, and T10C.  We first saw them at Mandarte Is. and they were traveling northwest.  Then at 1400 hours they switched direction and started heading north towards Stuart Island.  Then entire time they were traveling.  We also found traces of whale poo!  It was another interesting encounter with the Transients.  It was a surprise encounter as well because they just popped out of the water and shocked us all!  Finally at 16:20 hours we did the localization exercise with the array and our sound source on the dinghy.  The position of the exercise was at N 98 degrees 34.902 W 23 degrees 11.881.
The data was uploaded to the Beam Reach computer and will be analyzed at a later date.
