Sampling frequency matters! Our new study utilizes a low-cost, high-freq system to track GHG fluxes over 7 months. If we don't measure often, fluxes can get heavily skewed. That's why affordable, high-freq systems are a game-changer for tracking freshwater GHG fluxes. doi.org/10.1002/lom3...
Quantifying temporal dynamics of greenhouse gas emissions in lake mesocosms: Deployment of a low‐cost measurement system
Greenhouse gas (GHG) emissions from freshwater ecosystems contribute significantly to global carbon budgets, yet they remain poorly constrained due to limited high-frequency measurements. We tested a...

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.

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!
