Don’t mind us, just recovering a buoy and upgrading it for more high-frequency data gathering!

Testing the ECO ADCP at Lake Ormstrup (thanks to our colleagues in Roskilde who lent it to us!). Now, we hope for the wind to pick up, so we can measure some velocity profiles.

Congratulations to Olivera on this really nice paper! This paper was possible thanks to the wonderful AQUACOSM project which supported many transnational access days to collaborate with us using our unique mesocosm infrastructure.

Nutrient inversion but not warming drive changes in periphyton biomass and composition in shallow lake mesocosms
Periphyton plays an important functional role in shallow lakes and is sensitive to variation in nutrient availability and global warming. Understanding the responses of periphyton to changes in nutri...

The aim of this home made, low cost, system Ed is working on is to measure fluxes of carbon dioxide and methane (diffusion and bubbles) 6 times a day, 7 days a week, hopefully 365 days the year on all 24 mesocosms. That will 52 560 flux estimates, though we might miss a couple over the year!
@edevardtdanielsen.bsky.social, @tubabucak.bsky.social, @etileter.bsky.social and @thosdavidson.bsky.social launched Ed’s PhD project at the Lemming mesocosms! We study how nutrients, temperature, and macrophytes affect oxygen dynamics and GHGs in aquatic systems. Excited to see what we uncover!

splendid paper this one!
Your model is your hypothesis. So, why not use multiple of them? Championed by Feldbauer & Mesman, in our fresh-off-the-press paper we highlight the performance of temperature models across the globe, and discuss the path forward to get better projections!

How can we build better predictive models? And what can AI tell us about complex ecosystem mechanisms?
I’m hiring a PhD student to work with me on applying data-driven discovery methods on high-frequency lake data to begin September 2025. Application is due on May 4.
