I'm so excited to share our new paper in Global Change Biology: A network of 18 wildfire chronosequences reveals key environmental drivers and knowledge gaps in the boreal nitrogen balance, with @michael-gundale.bsky.social and others. doi.org/10.1111/gcb....

Big CONGRATS to @kacizarek.bsky.social!!! Her new paper is out in @agu.org's JGR-B!

The paper has a little bit of everything -- N biogeochemistry, intermittent stream hydrology, concentration-connectivity relationships!

Check it out here: agupubs.onlinelibrary.wiley.com/doi/full/10....
Conceptual figure illustrating predicted biogeochemical responses to changes in network connectivity and streamflow. (a) At the watershed outlet, we predicted NO3− export would increase in response to increasing watershed‐scale connectivity and streamflow, resulting in an enrichment of NO3− downstream. As watershed‐scale connectivity (active surface drainage network length) and streamflow decrease in the dry‐down, NO3− export will decrease due to N source limitations. (b) Throughout the watershed, we predicted the seasonal dry‐down period to be the greatest potential for denitrification to occur given the availability of both NO3− and dissolved organic carbon, anoxic conditions, and decreased streamflow.

Do you work on lakes globally? Check out what is, to my mind, the most complete global database of lakes (~6M) and associated attributes, newly published in WRR. Also the basis for SWOT lake data. agupubs.onlinelibrary.wiley.com/doi/full/10....
Map of global lake distribution, colored by the number of SWOT overpasses per 21 day cycle. There are many lakes with a high number of SWOT overpasses at high northern latitudes, but there are also tens of thousands to more than a million lakes on every continent. Lakes are graphed by latitude and longitude on the edges of the figure.

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.

"Abrupt transformation of west Greenland lakes following compound climate extremes associated with atmospheric rivers". This new article in PNAS by Jasmine Saros and colleague Vendy Hazuková is pretty striking www.pnas.org/doi/full/10....

My first post on bsky to announce my first solo author paper is out in @aslo.org L&O Letters. doi.org/10.1002/lol2...
Thanks to lots of amazing conversations with collaborators and a call out on that other social media to gather info on lakes, rivers, streams, wetlands, etc with calcium carbonate.
Images of calcium carbonate deposits as travertine, covering leaves, as microbialites, on a macroinvertebrate, as a whiting event in a lake, and as a benthic microbial mat.

We often think of rivers as linear features, but lateral dynamics are just as important and often overlooked!

In our paper we present a framework for the study and management of rivers which emphasises lateral connectivity.

The sky above Umeå has been colorful lately (when it's not pitch black that is).
Everyone in IceLab has seen these.
Except the fish. 🐠
They're just doing their regular fishy things.

Yesterday's single #nacreous cloud was nice, sure, but this morning we had an explosion of them! Again, everyone in Umeå seemed to have something to say about them. We are all connected in our awe or rainbow clouds. #cloudappreciation #photography #LifeNearThePoles

I am soon recruiting two PhDs and a postdoc, to work on carbon, methane, metabolism in arctic stream networks. Glad to chat potential opportunities during #AGU24 @agu.org ! There is also soon another postdoc position on oxygen responses to peatland restoration with @ryansponseller.bsky.social ⬇️
