Spent a couple of days in the lovely peatlands of northern Minnesota installing and maintaining equipment to measure gas fluxes.

Just out in PNAS - Been thinking about these three graphs for nearly a decade with a great team of smart colleagues. We finally have a story to tell that makes these interesting observations make sense. doi.org/10.1073/pnas...

Freshwater science researchers: Join the #ASLO_ECC and the Society for Freshwater Science (SFS) for the virtual networking event "Building Bridges in the Aquatic Sciences" on 28 Oct (1:00 PM ET). Learn more about funding opportunities, research pathways, and more 🔗 www.aslo.org/building-bri...

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! (If you just can't wait to see what's inside, it's already available online: www.canr.msu.edu/resources/aq...) #MacrophyteMonday

Curious about ecosystem metabolism of tropical rivers? Check out our new @aslo.org publication in Limnology and Oceanography on the role of hydrological seasonality and ecosystem metabolism in rivers of Mexico! #ecosystem #metabolism #rivers 🌎 aslopubs.onlinelibrary.wiley.com/doi/10.1002/...

Join us for our summer public open house! When: Friday, July 18, 2025 from 2 - 4 p.m. Where: NRRI Duluth - 5013 Miller Trunk Highway, Duluth MN 55811 What: Researchers will highlight opportunities for MN to lead the transformation of bedrock industries.

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.

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 #FireLakes #NRRI #LCCMR #MNENRTF

Here is a little insight into the effect of forest fires on lakes here in Northern Minnesota - work led by NRRI researchers 🌎

Fairy shrimp! Kicking off a new project focusing on seasonal pond food webs located in the Superior National Forest.

Well done Hasara! 🎉🎉

A huge congratulations to #SHSU Biology student - Hasara Siriwardane @hasara.bsky.social on her successful defense of her Master’s thesis! Well done Hasara!

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?

‼️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. More by @afreedma.bsky.social here:

We are looking for a Director of Research at the Natural Resources Research Institute (NRRI), University of Minnesota Duluth -- come work with us in beautiful northern Minnesota! hr.myu.umn.edu/jobs/ext/366...

🇨🇦Job alert🇨🇦 Three tenure track positions in Biological Science at UManitoba, 2 on aquatic organisms, 1 in synthetic biology/biochem. Ask me anything about living and working in #Winnipeg -it’s pretty good here! (And in 2025, “pretty good” is actually great imho)! universityaffairs.ca/jobs/job-pre...

In this new review/conceptual paper in J Env Mgmt, we argue for the need to open the black box of internal biogeochemical and ecological processes in order to better manage stormwater ponds to enhance the water quality benefits they provide to society. www.sciencedirect.com/science/arti...

Sunrise on Lake Vermillion, MN today - lovely way to start a Friday.

For scientists interested in large lakes of the world. Contact us if you'd like to be added. Space still available.

Do you study or work in non-perennial, intermittent or ephemeral streams? Please take our survey to better understand the data, opportunities, and challenges of your research!

Fun and quick trip to visit the University of Minnesota’s Saint Anthony Falls Lab for their open house - all kinds of flumes and even a wind tunnel! So cool and inspiring!

A view fall sites from in and around Duluth. Loving all the colors!

It was wonderful to get out into a couple of Duluth’s local streams this week!

The Bonfire site to purchase SFS merch is up and running now! www.bonfire.com/society-for-...

I have officially relocated to Duluth, MN where I will be a research associate at the Natural Resources Research Institute (NRRI) in a couple of weeks. So thankful for my colleagues and students at #SHSU - it has been bittersweet to leave lovely people & so exciting be back in MN!

We're hiring! Work with @jbaron4.bsky.social @mishafredmeyer.bsky.social, and I to synthesize 40+ years of biogeochemical data from lakes across the southern Rocky Mtns. Pay range $65-75k, negotiable start date jobs.colorado.edu/jobs/JobDeta...

The Blue Bonnets are hear in east Texas!

So wonderful to have my eldest niece Emma visit me for spring break. Finally checking out the huge statue of Sam Houston just outside of town. Better late than never.

It's REU season! Applications are popping up across the network. You can see them all at lternet.edu/education-an... Please share widely, and let us know if you don't see your site's program!

We are missing the snow here in northern Minnesota, but we do have awesome ice for skating along Lake Vermillion!

Oliver wasn’t quite so thrilled about his new hat I bought him for our upcoming Minnesota Christmas…

Kicking off my feed on this new site with a call to check out the Aquatic N Fixation RCN if you haven't yet www.aquaticnfixation.com - and if you study N fixation, keep your eyes peeled for our special sessions at the #ASLO and #SFS meeting in June!

2 fully funded PhD positions with Charlotte Alster (researchers.lincoln.ac.nz/charlotte.al...) and myself! Come work at geothermal sites in Aotearoa New Zealand to explore how warming influences microbial trade-offs, food web structure, and soil ecosystem resilience. @marsdenfund.bsky.social

~1 more week until our planned 1st review of applications for a new Analytical Laboratory Manager at Virginia Tech! Please share widely & reach out if you have questions. Stream Team is an inclusive & collaborative group + Blacksburg is a lovely little mountain/college town. @careylab.bsky.social

I have multiple funded positions for MS or PhD students working on data science and hydrology. To apply, send a cover letter, resume/c.v., and contact info for 3 references to jhosen at purdue.edu. For more information go to jakehosen.github.io/DataScienceE... or contact me.

Lovely day in the field at our local field station to download sensors! Hasara and Erica are two of our SHSU graduate students doing stream research.

Oliver is having a great Thanksgiving weekend so far!
