Blue whale CEE -- interupted by a sea lion

We pushed off from Pt. Sal at dawn in a cool mist - it's a small and uninhabited point north of Vandenberg AFB that we shared with a colony of sea lions for the evening.  On the way out we saw a number of them and a harbor porpoise, then several groups of humpback whales.  This included the mother and calf pair in the pictures below that were both repeatedly breaching in turns while the mother was slapping her pectoral fins on the surface.  [Note: these pictures, like any others of animals taken for SOCAL-11 and posted here or on the SOCAL-BRS.org website, were obtained and are displayed according to the conditions of NMFS permit #14534.]                                                                           

   

Humpbacks are not among the focal species for SOCAL-11, however, and we had to search around a little bit for a good candidate animal of one of our focal species.  We managed to tag an adult blue whale by mid-morning and once we had done our baseline monitoring and met our pre-exposure conditions we began transmitting the experimental sound in the water.  Eighteen minutes into our intended 30 min sound sequence a California sea lion began swimming directly at us to investigate the sound source.  When this adult male came inside our 200m exclusion zone we ceased the transmissions as a required shut-down measure.  Like two sea lions last year, this guy seemed curious about the sounds we were projecting rather than bothered by them.

We are steaming down the Santa Barbara Channel at the moment in less ideal weather conditions.  We will be working around the northern Channel Islands part of tomorrow and then working our way south.
