Wow! Summer winded down quickly. It felt like a lot of time spent writing, some exciting and stressful glider piloting, and I wrapped it up with 2 weeks on the water in Southern California working on the SOCAL BRS project. (You can read a public summary of the project here).
I’ve talked about this project before, and this was my 4th summer on the R/V Truth. This leg ended up a bit frustrating in the fact that the animals were more difficult to find and work with than past years. We didn’t observe the distribution of whales we typically do, and we suspect this has something to do with the abnormally warm waters off Southern California this summer.
For example we barely saw any Risso’s dolphins, where typically there are tons around Santa Catalina Island. And the blue and fin whales typically found feeding right in the LA shipping channel weren’t where we expected them. Instead we found them quite a bit further offshore near Santa Barbara Island. AND we saw schools on schools on schools of yellowfin!! (I think……I may edit this in a day or two…anyway I’d never seen so many leaping fish!) EDIT: Yellowfin tun and maybe some small bonitos and maybe some bluefin.
For me the trip was still a great learning experience. I got to use some new tools and learn some new skills, including running the sound propagation software we use in setting up a CEE (Controlled Exposure Experiment), running the sound source that projects the sound playback, and deploying and recording from sonobuoys, little one-time use floating recorders designed to listen for subs, but also work for whales.
