SOCAL-13 Phase I End

  We have come to the end of the first full research phase for the SOCAL-BRS project in 2013. In terms of our success with the high-priority beaked whale species, this was the most successful period we have had in this project. We had two successful tag deployments (see above – taken under NMFS #14534-2, […]

Big Whales and an Old Friend

We’ve been offshore for another few days on the first phase of our SOCAL-13 experiment and just back in to recharge for our last few days. We have had reasonably good conditions the last few days and have been searching for beaked whales but haven’t had the luck with them we had last week. We […]

Beaked whale bonanza!!!

Sorry for the radio silence with the SOCAL-13 blog. We have had very good offshore conditions and great success accordingly! In fact, the last five days have seen multiple beaked whale tags deployed and multiple groups seen with many other near-miss approaches, which is a first in our efforts out here. We have gotten two […]

BEGIN SOCAL-13

We are happy to report on the start of our SOCAL Behavioral Response Study for the 2013 field season (SOCAL-13). After several days of field efforts offshore we are back in internet range to provide an update on our progress. As a reminder for those of you following the blog or others that have just […]

NEW SOCAL-BRS PAPER ON BEAKED WHALE RESPONSES TO SOUND EXPOSURE

A second paper from the SOCAL-BRS project was published today as well. This paper (in Biology Letters) presents results for the responses of beaked whales to both controlled and incidental exposure to mid-frequency sonar signals. The reference for the paper is: DeRuiter SL, Southall BL, Calambokidis J, Zimmer WMX, Sadykova D, Falcone EA, Friedlaender AS, Joseph JE, […]

NEW SOCAL BRS PAPER ON BLUE WHALE RESPONSES TO SOUND EXPOSURE

We are pleased to announce the publication of a new paper in the Proceedings of the Royal Society – B from our Southern California Behavioral Response Study on responses of blue whales to simulated sonar and other human sounds. The reference for the paper is: Goldbogen JA, Southall BL, DeRuiter SL, Calambokidis J, Friedlaender AS, Hazen EL, […]

Dr. Ari Friedlaender’s Smithsonian Blog on Blue Whale Feeding

We are proud to note that our very own Ari Friedlaender wrote a great blog for the Smithsonian’s Ocean Hall on our recent paper lead by Jeremy Goldbogen on feeding mechanics in blue whales <see: http://sea-inc.net/2012/12/06/new-paper-on-blue-whale-feeding-behavior/>. The text is below and you can find it online at <http://ocean.si.edu/blog/acrobatic-blue-whales-do-twist-while-feeding> ______________________________________________________________________________________________________________ I have a vivid childhood memory […]

New Paper on Blue Whale Feeding Behavior

    We are proud to announce the publication of a new paper on blue whale feeding behavior that features tagging data collected within the Southern California Behavioral Response Study (SOCAL-BRS) project. The paper is entitled “Underwater acrobatics by the world’s largest predator: 360° rolling manoeuvres by lunge-feeding blue whales“ Dr. Jeremy Goldbogen, a post-doctoral […]

Blown out to end SOCAL-12…

Well our marginal weather conditions ended and Mother Nature rendered the last few days of our SOCAL-BRS project this year ones of just trying to get back safely. We did and while we broke some things fortunately they were just things. We had to duck into Santa Barbara Island and hide in the minuscule wind […]

SOCAL-BRS

SOCAL-BRS is a study of basic behavior and responses to controlled sound exposures in a variety of marine mammal species.
