Making the ocean even smarter II

Most underwater communication signals will likely be acoustic, and likely be in the 8kHz – 25kHz range; overlapping human auditory range, and smack-dab in the sweet spot of marine mammal hearing range (as well as some fishes, and likely some marine invertebrates…).

Long distance calling!

While there are a number of varied species of baleen whales that are adapted to their particular habitats and natural histories, there are a few things they have in common; they’re all much larger than we are, they all graze…

All a matter of perspective

I’ve just finished up a week in Pittsburgh, PA at an Acoustics Society conference. Because sound and acoustics intersect so many fields, Society meetings are some of the most diverse gatherings of disciplines under one roof – with sessions on…

Bio-inspired communication signals

Of the many papers presented this week at the Institute of Electronic and Electrical Engineers/Marine Technology Society (IEEE/MTS) Ocean conference two really stood out as possible solutions to the impacts of communication signals on marine mammals. These papers discussed using…

New discovery of songful bowheads

It’s always a delight to learn something new about ocean life. Some 40 years ago whale researcher Roger Payne came to understand that Humpback whales sang complex, beautiful, and patterned songs. Their haunting melodies released in an LP as “The…

Singing fish lead to conservation programs

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…
