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.

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!

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.
