OCR associate and marine biologist Mario Rivera has received coverage in Costa Rica’s “El Financiero” for his work with singing fish. He is using sound-pattern recognition software to identify breeding aggregations of fish – in this case “weakfish” (Cynoscion squamipinnis) to determine…

Shipping noise correlated to stress in whales
A recent paper in the Proceedings of the Royal Society correlates shipping noise with stress levels in baleen whales. Heretofore this has been a difficult assumption to prove because we do not have any baseline of whale stress levels prior…
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 little deeper into the International Quiet Ocean Experiment.
The 2011Internat ional Quiet Ocean Experiment (IQOE) brought together leading scientists and researchers [download] to dig deeper into the issue of human generated noise pollution with the objective of determining what we know, what needs to be known, how…
Crustaceans need ears too!
A preponderance of marine bioacoustic work has been focused on marine mammals – whales, dolphins, and pinnipeds. This is in large part due to the “charismatic megafauna” paradigm where big, complicated animals with recognizable expressions attract most human interest. While…

Report from the International Quiet Ocean Experiment
Last week I attended the “International Quiet Ocean Experiment” (IQOE) at the UNESCO headquarters in Paris. The founding premise of the meeting is a bit outrageous – that somehow all maritime nations could come together and halt all of their…
The International Quiet Ocean Experiment
By the time you might be reading this I will have been conferring with colleagues and associates at the UNESCO Headquarters in Paris under the rubric of the “International Quiet Ocean Experiment” (IQOE). The purpose of the meeting is to…
New lab evidence substantiates noise impacts on invertebrates
Bioacoustician Michele André et.al. from the Catalonian “Laboratory of Applied Bioacoustics” has published a paper which examines the impacts of low frequency (50Hz–400Hz) noise on cephalopods – squid, octopus, and cuttlefish. Exposed to surprisingly low levels of sinusoid noise…
Aran Mooney et. al. dig deeper into squid hearing
Aran Mooney was the Principal Investigator on a project to determine the hearing sensitivity of squid. An article this week in the Woods Hole Oceanographic Institute newsletter describes the research and its importance to commerce and ecology. We know from…
