I’m excited to share that I received the Villum Young Investigator grant. Thank you! In this project, I’ll develop new ecosystem models to improve our projections of stochastic processes, ie, turbulent mixing and algae dynamics. The grant will fund a PhD, a postdoc, and high frequency monitoring.

Clarifying the trophic state concept to advance macroscale freshwater science and management
For over a century, ecologists have used the concept of trophic state (TS) to characterize an aquatic ecosystem's biological productivity. However, multiple TS classification schemes, each relying on...

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.

THE BUOYS ARE BACK IN TOWN!
We got new buoys today to extend our lake monitoring for the Danish Long-Term Ecological Research. These will extend our high-frequency data sets of oxygen and temperature in two new lakes to better understand slow as well as rapid environmental changes.

Here's is my experience from the financial crisis of 2008 (and Covid). Even though the whole way we are doing and funding science has changed significantly, people's shortcuts for determining whether or not you are "succeeding" will take longer to recalibrate. /1
I wonder, for those of us on a tenure clock, how will this situation factor in?
We’re not playing the same game we set out to play.

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!

Work with me on getting depth-discrete profiles of water quality using high-frequency loggers and microCTD measurements! And then let’s be creative to infer mechanisms that could improve mechanistic modeling.

Great paper that highlights the performance of four lake models (bulk, energy balance, and 2x k-Epsilon models) on lakes, globally! There’s no clear winner. Some perform well there, some better there. So, using ensemble modeling is the path forward to improve projections and state uncertainty 🌊🌡️💧
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.
