Oil and Gas exploration implicated in dolphin strandings

Over 675 dolphins have been found dead along the Florida to Texas Gulf Coast since February 2010. Initially people suspected that the BP oil spill and dispersant use might be to blame. A report from NOAA corroborates this with a finding that some 32 live dolphins show signs of chemical stress with liver and lung […]

Noise impacts on fish and invertebrates workshop

I spent last week in San Diego attending a workshop sponsored by the Bureau of Ocean Energy Management (BOEM) on the impacts of human generated noise on marine fish and invertebrates. Having watched the field of ocean noise impacts roll slowly forward in fits and starts for 20 years, this workshop is really a breath […]

Tracking walrus’ movement using only one ear

A recent paper was published by marine research firm JASCO on localizing walruses using a single hydrophone. The technique they have refined is detailed in the article and involves assessing “multipath signals” – echoes from the sea surface and seafloor – along with the direct signal to track the movements of walruses in the Arctic. […]

Marine Scientists express themselves through CNN

An article appeared today in “CNN Opinion” by Chris Clark and Brandon Southall focused on the impacts of noise on marine life. It is an informative read and also highlights two important trends in the field. First, it points to a trend in impact awareness and research from incident-specific catastrophic impacts (such as sonar induced […]

Yesterday BBC News put out a feature article on ocean acoustics. I suspect that this is really making the rounds because many folks have brought it to our attention. For good reason too, as it includes some great embedded sounds, references to other useful resources, and a couple of conversations with folks in the field, […]

The Arctic is on Everybody’s Sonar Lately

Last week we attended an Acoustic Society conference in San Diego. This time I didn’t deliver a paper so it was mostly a reconnaissance trip – both to catch up with colleagues and to introduce Gwynn, our Digital Assets Manager to the field. It is not a surprise that many of the bioacoustic papers that […]

Throwing Precaution to the Wind – and the Waves

A recent IBM press release on an ocean noise monitoring project caught the attention of Forbes and other press this week because of a bit of an ironic twist: Our lack of precaution in developing earlier energy technologies – fossil fuel and nuclear, has sensitized us to potential problems in advancing new sustainable technologies like […]

The Acoustic Ecology of Geophysical Surveys

OCR advisory board member and acoustic ecologist Jim Cummings sent us a New York Times article about life aboard geophysical research vessel (RV) Marcus G. Langseth wherein marine geologist Bernard Coakley writes about the acoustic environment aboard the vessel after winding down a survey operation. He writes that while a lot of the compressors, airguns, […]
