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 Paper on “200 kHz” sonar with side lobes audible to marine mammals

    On behalf of my co-authors, I would like to let you know about a new paper on the audibility of high frequency sonar systems to some marine mammals. We investigated the acoustic “leakage” of energy into side lobes from the 200 kHz center frequency of three commercially-available sonar systems. These active sonar systems […]

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 […]
