Oxygen supersaturation has been reported to protect aquatic animals from heat waves. We tested this in a large collaborative experiment on many species of fish and crustaceans. Our new paper in @plosbiology.org shows that the effect of hyperoxia on thermal tolerance is negligible. Unfortunately.

Sad that ChatGPT makes up two male scientists instead of the real scientists Andrea Franke and Catriona Clemmesen.

And here is young me moving in to that empty office 10 years ago. And starting the NTNU lab with Rachael and four aquaria.

Cleaned out my office at NTNU, exactly 10 years after moving in. Looking at the list of people who passed through the lab, so many great scientists and friends!

Yes, I feel a little sentimental.

New fish species keep popping up in Sweden, most likely because of ocean warming!
Today a large Mahi Mahi in Lysekil!

This is very worrying! Zero eels per hour of fishing for many trawl surveys!

Yes, looks very much like the harbour porpoises we see here in Scandinavia, in both shape and behaviour.

The Kristineberg Underwater Observatory is now live!! 🐟🧪🦑

Watch the eel grass meadow full of life live from your desk! Gobies, crabs, pipefish, several species of wrasses including some massive Ballan wrasse. Enjoy!

Warming waters mean new warm-water species! The venomous lesser weever and the gilt-head seabream have almost no previous recordings in Sweden but our catches may mean they’re getting more common.
