This gem of an #AI marine logo(?) graced my screen. I can't pick a favorite: - Dolphin tunas - The seal with: - a three point tail - connecting dorsal and pectoral fins - ant eater face merging with sky - Sky whale - Smaller sky polar bear - boat? - MARINNE CONIEERATIO⼏|

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.

Next we have Line A Kyhn, former lab member, presenting results from our joint #USBL study, technology which needs more regulation as their presence dramatically reduces how much time porpoises spend in their habitat.

New paper! Here we report four opportunistic observations of orcas harassing adult male sperm whales near Andenes, Norway. In one instance of recorded audio one sperm whale, using a series of clangs and codas, appears to call to other sperm whales nearby when approached by a group of orcas. See 🖼️⤵️.

This week I'm out in the Danish #BalitcSea on the #SAMBAHII Project, working to monitor the remaining 500 Baltic #harborporpoise. Here, we are deploying a 4-channel array to calculate the #dectectionFunction, or the likelihood of detecting porpoise #echolocation in the study area.

Bonfires are pretty, but I consider myself lucky to round out midsommer off the coast of Møns Klint.

Last week, @mialybkaer.bsky.social, Ellen Jacobs, and I traveled to @vliz.be as part of the @dtobioflow.bsky.social project! We got into the nitty gritty to bring #porpoise pod 🔊 data to the #DataLake via @aquatictracking.bsky.social. Very excited to make this #bigdata 🔢📈 project a reality.

Researchers from the Marine Mammal Research division at Aarhus University and the European Tracking Network group at the Flanders Marine Institute met in Begium at VLIZ to discussion our big data goals. Image is of 9 researchers standing outside in the wind in front of a building.

Often in first drafts I confuse my homophones and realize in the read-through I've used the wrong word. For example, here, I was trying to type pull the line taut, not taught. However, what is with this grammar suggestion? What does 'train to the train' mean? How does it come from 'line taught?'

Small screenshot of Microsoft Word grammar suggestion of 'Pull the line taught' to 'train to the train.'

Surprisingly, USBLs were detected at ALL stations (‼️), indicating that USBL signals are far more prevalent than what is currently reported. As for disturbance, the presence of USBLs had a significant negative correlation on the probability of porpoise positive minutes (PPM) detected. 🧵3/6

Bar plot with the results of the Control-Impact analyses on porpoise positive minutes (PPM). Model predicted mean and 95% CI intervals (in black) are provided for control and impact stations contrasting PPM between periods without USBL signals (blue bar), periods with USBL signals from other sources (orange bar) and USBL signals from survey vessels (red bar). The letters below the bars indicate whether the predicted mean between groups is significantly different at a p-value of 0.05. As such, bars with similar letters indicates that the mean PPM between groups do not differ from each other, while bars with different letters indicates that the mean PPM between groups differ from each other.

At the control stations, there is a significant difference between porpoise presence during unknown USBL activity (other sources) and without. At the impact stations, there is a significant difference between porpoise presence during known and unknown USBL activity, and without.

The prevalence of ultra short baseline acoustic position systems, also known as USBLs 🔊, is understudied in #EuropeanWaters and its effect on marine mammals 🐋, such as the #harbourPorpoise, is mostly unknown. These systems are used in #geophysicalSurveys and during #trawling fishing activities. 🧵1/6

At #ECSconference2025 @crisbri.bsky.social made a compelling #BlueAnthropocene argument: that animals are living in a world heavily and historically influenced by us. #CulturalEcosystems require historical context.

Heading to #ECSconference2025 this weekend in the Azores! Exciting to take part in noise and SAMBAH workshops, and to present this observational report of #orcas harassing #spermwhales in northern latitudes. Paper forthcoming, but for now, stop by and see my poster, I'll tell you all about it!

Some days you're at sea counting whales 🐋 🐬. Some days you're in deep with your code, solving puzzles👩‍💻🧩🔢. And some days, you're stuck in an elevator with 700 kg of stones.
