End SOCAL-15 Phase II

Tagged Blue Whale_J Calambokidis

Well we have come to the end of our field effort for the SOCAL-BRS summer 2015 effort. We have had some good accomplishments, including tagging 9 animals of three of our four focal species (fin and blue whales plus Risso’s dolphin – we did not manage to tag a beaked whale this time). We were […]

Warm Waters and Offshore Whales

BRS

SOCAL-BRS is progressing well in some ways, despite the extremely limited distribution of large baleen whales in some of our typical coastal areas. As you may have read, the strong El Nino conditions that are setting up off California have resulted in some very warm water temperatures. As a result, we are seeing a lot […]

Good start with fin whales

SOCAL-BRS is now operational for our second field phase of 2015. We are working with several research vessels including the Truth out of Santa Barbara and have been searching the coastal and offshore waters for our focal species. These include endangered blue and fin whales as well as beaked whales and Risso’s dolphins. Again, you […]

New SOCAL-BRS publication on foraging kinematics and prey distribution of blue whales

Goldbogen_2015

On behalf of the SOCAL-BRS project, I am happy to announce the publication of another paper resulting from our work. Lead by Dr. Jeremy Goldbogen of Stanford’s Hopkins Marine Station with a number of colleagues from the SOCAL-BRS team, this paper focuses on the fine-scale kinematics of foraging behavior in endangered blue whales and how […]

New Publication on Detection of Complex Sounds in Seals and Sea Lions

Complex masking

On behalf of lead author Kane Cunningham, we would like to provide some information on our recent paper on the detection of complex sounds by seals and sea lions.  The goal of this study was to test how auditory data predict detection of complex sounds in quiet and noisy conditions.  Our results indicate that pinnipeds […]

SOCAL-BRS

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