What Noise Annoys an Oyster?

Oysters with Acceleratometers (photo by Jean-Charles Massabuau) When the ocean noise pollution issue came up on everybody’s sonar, the main concern was about the impact of noise on whales and dolphins – what we in our industry refer to as…

Report from Omaha

A bit over two weeks ago I was in Omaha, Nebraska, at “The 4th International Symposium on Acoustic Communication by Animals.” This event is put up every few years by the Acoustic Society of America (ASA) and allows scientists outside…

Field report from Barcelona – OceaNoise 2017

I spent last week at Vilanova i la Geltrú – just down the coast from Barcelona, Spain at OceaNoise2017, a conference specifically focused on ocean noise pollution issues. All conferences have a purpose, but this one also had a personality.…

The sound of climate disruption

It has been known for quite some time that excessive anthropogenic carbon dioxide is modifying ocean chemistry, increasing acidity, and compromising shell growth in calciferous sea life. The effects of this have been confirmed in sea snails, corals, and oysters,…

Expert Opinions

  This week I have been hopping in and out of the Society of Marine Mammologists conference in San Francisco. This is an international event and brings mostly scientists from around the world to discuss all things Marine Mammal –…

Detection, Classification, Localization and Density Estimation

Last week I attended a workshop on the detection, classification, localization, and density estimation (DCLDE) of marine mammals. This field of inquiry is maturing around the development of more productive use of “Passive Acoustic Monitoring” (PAM) – which is essentially…

A bit of game changing going on

In 1972 the Marine Mammal Protection Act (MMPA) was crafted as a response to scientific and public concern that certain marine mammals would become extinct unless they were protected by regulatory intervention. It was the first ecosystem based regulation –…

We’ve come a long way from the “Silent Seas”

It is amazing how many people in the field of ocean science and conservation credit Jacques Cousteau as the inspiration for their love of the sea. Just when color TV was migrating into the American living room Cousteau was offering…

The little things that count (also)

In the early years of the ocean noise discussion there were heated debates about whether or not introduced noise was really harmful to marine life. Our understanding was shallow and the tools blunt. Even when animals washed ashore deafened, dead,…

Getting away with being nice.

This week Ker Than from National Geographic asked us for a critique on recommendations that came out of a study on the impacts of seismic surveys on Gray whales. The research was conducted by an “A Team” of scientists pulled…
