New Paper: Using acoustics to learn about harbour porpoise behaviour in tidal environments

Last week our colleagues at SMRU and PAMGuard published a paper on an approach they developed to successfully find and track harbour porpoise in tidally active areas. Their paper entitled Passive acoustic methods for fine-scale tracking of harbour porpoise in tidal rapids was published in the Journal of the Acoustical Society of America.

Ursula co-authors a new porpoise paper

SMRU Consultings Ursula Verfuss has co-authored another paper that is now available online. The paper is entitled: Diel and seasonal patterns in acoustic presence and foraging behaviour of free-ranging harbour porpoises. This links nicely to our last blog on “Listening to Echolocation Clicks with PODs” and is a great example of how echolocation behaviour collected from PODs can be interpreted.

#TBT: Real time PAM mitigation

This blog post is part of SMRU Consulting’s #ThrowbackThursday (#TBT) series. On Thursdays we’re going to posting about projects from way back when, many of which are part of developments that are consented or up and running. This #TBT blog is about our development of a real-time monitoring buoy to provide live detections of dolphins and porpoises during a port construction in the UK.

Avoiding High Frequency Vessel Noise on Porpoise

A new paper in published in Nature has found that harbour porpoises react to low levels of high frequency vessel noise. Odontocetes (toothed whales, dolphins, and porpoises) in particular rely heavily on the propagation of underwater sound for essential life functions including communication, navigation, and foraging.

OCEAN NOISE IS ON THE RISE and it’s important to determine the impacts of these changing conditions on cetacean populations.
