It was a fun afternoon of sharing the work we do at @umnnrri.bsky.social to visitors for our open house last week. Lots of science and work to be shared! My role was to talk about our awesome eddy covariance towers and peatlands in Minnesota!

Our new field guide just arrived from the printer! So happy. Can't wait it to get it into people's hands!

I have a fully funded PhD position open for start in Jan or May 2026. Field work in peatlands of the Northwest Territories, with lab work to understand potential downstream mobilization of carbon, nutrients, mercury after thaw or wildfire. Reach out for more information, and please send on!

Superior National Forest seasonal ponds are drying quickly! We are down to 2/9 of or study sites with water yet. We did however sample some of these lovely Dytiscidae larvae from one pond that will likely be gone tomorrow.

Wildfires could leave lakes murky for years Research that began after the 2021 Greenwood Fire seeks to understand how wildfires affect a lake’s water quality, and for how long. It also looks at what that means for mercury accumulation in fish.

When you're a limnologist you worry about lakes and water quality. NRRI's Chris Filstrup was concerned after the 2021 Greenwood Fire and quickly jumped into research mode, launching a study to find out more. This year, that work is even more important. bit.ly/4dAfRj4

Ha! That’s true - but does that mean the modeler is getting into the field?! Yes - I changed institutions. All was well at SHSU - but was able to find a great position with more focus on research and allowing me to move β€˜home’ - this is the closest I have lived to family in 25 years!

Hi Enrico! I hope you are doing well!! That is wonderful to hear that you like the MX loggers! I ended up going with the MX pressure logger - so far testing in the lab they seem to work great!

Anyone have experience using the Onset HOBO MX Water Level Data loggers? I have used the Hobo U20L-01 for many years, but am interested in the MX series as they can be downloaded via bluetooth in the field. Any experiences for recommending the MX loggers or if you all found any major issues?

Scoop: U.S. delegation pulled from key U.N. climate science meeting The IPCC meeting in China is slated to determine the content in the group's next series of reports.

‼️The US-based @ipcc.bsky.social technical support unit (TSU) for Working Group 3 Co-Chairs has been terminated, and the US won’t be attending next week’s IPCC meeting where the AR7 chapter outlines will be approved.
