When the first extra-planetary astronauts shared a picture of the Earth rising over the moon’s horizon it gave all of humanity an opportunity to visually behold this beautiful blue planet we inhabit. It was both humbling and awe inspiring, and…

Report from Salt Lake City

Last week I attended the Acoustics Society Conference in Salt Lake City where I hosted a session on the Industrialization of the Ocean. There were a number of quality papers presented and some good ideas and comments presented on the…

Industrialization of the Ocean

Later this week I’ll be heading to the Acoustics Society meeting Salt Lake City. The meeting runs through the entire week with presentations and sessions on all matters acoustic – from Architectural Acoustics to Ultrasound Imaging. Animal Bioacoustics is among…

NOAA Tinkers with acoustical standards to appease industry

NOAA-NMFS Acoustical Guidelines review

Update on NOAA-NMFS Acoustical Guidelines

  On Monday we submitted our critique and suggestions for the NOAA-NMFS Acoustical Exposure Guidelines for “Level A takes.” These guidelines establish regulatory thresholds for just how much noise we humans can make before the damage to marine mammals requires…
