Horribly AI generated marine aesthetic logo.
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?

#Voted in #Denmark today, as i have been here for over 4 years!
The ballots are as long as CVS receipts.
Postdoc position(s) available!
Work on:
- Muskox movement ecology
- Ecosystem & carbon dynamics
These can be done back-to-back for someone keen on both topics or split into two separate roles.
π Full details in the attached flyer!

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

And, last talk of the day, Ellen Jacobs talks @dtobioflow.bsky.social and how we are working to harmonize #PAM #harborporpoise detections across Europe. @mialybkaer.bsky.social
New post-doc Xavier Raick gave an overview of his work with year-round #minkewhale residents in warmer climates.
Section Leader @signesveegaard.bsky.social summarizes 12 years of porpoise #PAM results, highlighting the importance of conducting a #poweranalysis to understand the meaning of your results.
Sorting #otoliths is hard work! But Lousie Mau dedicatedly takes on the task to report on what dolphins are eating in East #Greenland.
Rikke Guldborg Hansen discussed her #tagging results on the declining #ringedseal population within their ice habitat.
Yours truly presented the response of #spermwhales when being harassed by #Orcas off Andrea, Norway.
Anders Galatius discusses the potential evolutionary reason for the slight #sexualdimorphism found in #white-beakeddolphins.
Line Kyhn presenting how the number of detection positive minutes decreases in the presence of USBL signals.
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.
Professor Jonas Tielmann presenting the paths six minke whales took after being tagged in Scandinavia.
First up we have Prof. @jonasteilmann.bsky.social giving an overview of the hight ambitious North Atlantic #minkewhale #tagging project.
Live from the Danish Marine Mammal Symposium! Here I'll be posting talks given by @marinemammalsau.bsky.social scientists! Stay tuned ππ¬π¦ππ’π
'Reducing our dependence on whales as an energy source will send us sliding down the slippery, spermaceti-lubricated slope to socialism.'
This results in three sperm whales forming a defensive position against the harassing orcas. This audio, detailed in our paper, has also been made publicly available for potential use in other studies.
This work was spearheaded by Mel Cosentino.

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 πΌοΈβ€΅οΈ.

Our Senior Researcher Fredrik Christiansen completed the third photogrammetry field season on bowhead whales in Disko Bay, Greenland. Together with MSc student Oliver Nowak and local hunters, he measured over 500 whales during March to June to investigate their prey consumption and condition.

This work has been done in #Denmark with many folks at @marinemammalsau.bsky.social and NIRAS. Tusind Tak to the Danish Environmental Protection Agency and the Aage V. Jensen Naturfond for supporting research on the critically endangered Baltic harbour porpoise!
In the video we are using a crane to lift the array lander overboard, while our crane operator, the trustworthy deck boss Artur, monitors an underwater camera to make sure the lander settles correctly on the seafloor. Then Line Kyhn takes a GPS point to mark the position.
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.
Its that time again - the list of Ecology/Evolution/Marine Bio Labs recruiting grad students for Fall 2026 is live!

Bonfires are pretty, but I consider myself lucky to round out midsommer off the coast of MΓΈns Klint.
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.
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 π data to the #DataLake via @aquatictracking.bsky.social. Very excited to make this #bigdata π’π project a reality.
Small screenshot of Microsoft Word grammar suggestion of 'Pull the line taught' to 'train to the train.'
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?'
Terrific work spearheaded by Mark Mikaelsen and Line Kyhn at NIRAS, with co-authors Sidsel Marie NΓΈrholm (NIRAS), and at @marinemammalsau.bsky.socialΒ Signe Sveegaard, myself, and @beestfloris.bsky.social. Funding for this study was provided by #Energinet. Full report can be found here‡οΈ.

It clear that more focus on the use and impact of USBL systems is needed, especially to keep the source level π as low as possible. Taken measures could be:
- maximum USBL source levels as a technical criteria π«
- requirements to avoid unexpected and undocumented in source level variations. π
π§΅5/6
Additionally, the amount of time before a porpoise would return to an area was positively correlated π with USBL signals. Meaning, that if USBLs were detected at a station, porpoises would take longer to return after the geophysical survey was complete than if there had been no survey. π§΅4/6
