New paper on seismic surveys and mitigation of impacts on marine mammals

SEA Blog, A paper was on responsible practices for conducting seismic surveys in environmentally sensitive areas was published recently in Aquatic Mammals. The lead author was Dr. Doug Nowacek from Duke University’s Marine Laboratory, who is a close colleague of SEA’s president Brandon Southall who was also an author on the paper. A copy of […]

Catalina Rissos

It’s been a full few days for SOCAL-BRS, mainly working Rissos dolphins around Catalina Island. We tried to get further offshore yesterday and today but rougher offshore weather pushed us back in. We have had a few firsts the last few days including our first 12+ hour deployment on a Rises and our first experiment […]

Fin whale trifecta

We have been focused on baleen whales the last few days in the SOCAL-13 project, primarily fin whales. Over the past three days we deployed ten tags on fin whales (and one on a blue whale) and ran two CEEs plus a full control sequence with a total of seven tagged animals. All of these […]

START SOCAL-13 PHASE II – Double Rissos

We’re very glad to be back together for this last phase of our SOCAL-BRS project for 2013. We pushed out from Santa Barbara yesterday and came south in pretty good weather. A group of humpback whales has been working in some mixed-species aggregations chasing fish in the Santa Barbara Channel and we came across a […]

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, […]

New Paper on Amphibious Hearing in Pinnipeds in Special Issue of Journal of Comparative Physiology (A)

SEA blog, Please note the availability of a new special issue of Journal of Comparative Physiology (A) on Sensory Biology of Marine Animals (see below details and link). Within this issue is an original paper lead by Colleen Reichmuth at UCSC <www.pinnipedlab.org> to which SEA’s B. Southall contributed. This paper is available on request. Comparative […]

SOCAL-BRS

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