It's live! Please see my new paper in Ecological Informatics on the #detection and #categorization of frequency notched echolocation from wild recordings. 🐬🔊👇

www.sciencedirect.com/science/arti...
Graphical abstract for the paper 'A simple categorization method for frequency notched echolocation.' Here, we describe how from four passive acoustic monitoring stations in Skagerrak, echolocation clicks from white-beaked dolphins were manually audited. These signals exhibit distinct spectral peaks and notches between 20-80 kHz in 75-90% of visually confirmed species recordings. A nonlinear least squares model was used to dynamically map the spectral banding pattern. Our template was significantly correlated with 87% audited white-beaked dolphin events, making this a viable, computationally efficient method.

Fresh off the press from colleagues at the CMST lab (not on Bluesky), Australia. Paper focusing on Omura’s whale song features off northern Australia, published as JASA-EL EDITOR'S PICK

Omura's whale (Balaenoptera omurai) song features and structure in northern Australian waters
This paper describes Omura's whale vocalizations recorded off northern Australia. Most common was a two-unit “doublet” (17–50 Hz, peak 25.5 Hz, duration ∼15 s).

🤯 "perhaps most great whales have an unrecognized potential for great longevity that has been masked by the demographic disruptions of industrial whaling. This unrecognized longevity has profound implication for basic biology and conservation of whales." Astonishing stuff.

New paper alert
Extreme longevity may be the rule not the exception in Balaenid whales
by @alaskaraven.bsky.social , Els Vermeulen, and me.

♀Southern rights could live much longer than we thought (10% >130);
♀North Atlantic rights' lives are truncated (10%>47)

Whale life spans have likely been greatly underestimated.
