B. Southall Delivers Visionary Research Seminar on SOCAL-BRS at ONR S&T Expo

Dr. Brandon Southall gave an invited “Visionary Research” presentation at the recent ONR Science and Technology Expo in Washington D.C. This expo highlights cutting edge research and innovative technology supported by ONR. Given their long-standing support of marine mammal research in a wide variety of areas, including sound and it’s potential effects. Dr. Southall’s lecture […]

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

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

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 […]

New SOCAL-BRS Publication on Baird’s Beaked Whale Behavior

  We are pleased to announce a recent publication from the SOCAL-BRS project on the basic behavior and responses to simulated military sonar in a Barid’s beaked whale. These data were particularly significant in being the first high-resolution movement and acoustic measurements for any individual of this species. The photo above (Taken under NMFS permit […]

END SOCAL-14 PHASE II

After a few rough weather days – hot and windy with high seas – we got a break on our last day for this phase of SOCAL-14. It was nice and calm as we worked back towards our end point near LA and we found a number of different animals feeding on some rich aggregations […]

Making the most of it…

As you may have heard, the (second) hurricane off the Pacific coast earlier this week hit parts of Baja pretty badly. While we aren’t getting any direct effects of that (but thanks for the few emails we have received asking), we are picking up some of the swell from it mixing in with some local swell […]

Rough Seas…

It’s been a rough few days on the sea off southern California for the SOCAL-BRS effort. We need relatively calm seas (e.g, <10-15 kt winds and <3-4 ft seas) and if you check out the offshore actual weather and forecasts for the outer waters where we hope to work with beaked whales and other pelagic […]

Double Tagged Blue Whale – Close Interaction with a Large Ship

Though we had planned on working nearshore today in SOCAL-BRS with some planned refueling and transfers of people and gear, the small craft advisory from large swell and 20+ knot winds in outer water ensured it. Knowing the weather would be poor we got an early start with the objective of getting a baleen whale […]

Back From Offshore

Apologies for those of you that have been following the SOCAL-BRS blog for our 2014 field efforts for the few days delay (and thanks for the emails checking in on us!). We have been well offshore working the last three days and out of cell and internet range to get updates posted. We had reasonably […]

SOCAL-14 Phase II Start – Coastal Blue Whales First

Today marked the start of our second field phase of SOCAL-14. We are fortunate to have two full weeks of field effort to find, follow, tag, and study the behavior of different cetacean species in the beautiful Channel Islands off Southern California. For those of you who are not familiar with the project, it’s goals, […]

SOCAL-BRS

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