💡 For #MethodsMonday, we take a deep dive with @alexploring et al. into organic S as both source and sink to sulfate reduction in #LakeSuperior. Key were @SLAClab's particle accelerators, which shoot high energy x-rays at samples to learn about sulfur speciation. 🧵 to #ASLO_LO

Ready for a wild story about sulfur in Lake Superior? I've studied the S cycle in weird places (looking at you Mono Lake), but I'm still surprised by what we found here: organic S as both source and sink to sulfate reduction! Here's what that could mean for the ancient ocean...

Looking for an outstanding aquatic scientist to be the next Director of the Large Lakes Observatory. If you know one, please share: hr.myu.umn.edu/jobs/ext/358208

Do you know any meromictic lakes with surface sulfate in 100-400 uM range where sulfate in not coming from the bottom?

The Ozersky Lab is recruiting a Ph.D. student to join an NSF-funded project on the winter limnology of seasonally-freezing lakes. Please share widely! More info here: aslo.users.membersuite.com/community/care… and here: biolimno.weebly.com

EAR Postdoctoral Fellowships (EAR-PF) applications are due October 25, 2023 new.nsf.gov/funding/opport…

How can sulfur-oxidizing microbes thrive in a low-sulfate lake? Our paper reports on high biomasses of giant (centimeters!) Thioploca bacteria in Lake Superior: sciencedirect.com/science/articl…

Two years ago, I was on the R/V Blue Heron in Lake Superior, collecting (probably too much) water and mud! Today I am stoked to finally submit the first paper from this postdoc work with @EarthSciUCSB and @UmdLLO. Fingers crossed I can share this cool organic sulfur story soon!

The Kakhovka Reservoir was about the size of the Great Salt Lake (in both area and volume). Now it's gone.

Do you know any Ukrainian scientists? @WeizmannScience has a new visiting students/post-docs program for Ukrainians. Visitors will be hosted at one of Weizmann's labs and get monthly support of 5000 NIS (up to 6 months + accommodation/airfare). Link below: weizmann.ac.il/feinberg/suppo…

If you are a professor who is looking for students/postdocs/researchers and would like to support Ukrainian scientists, please put your name and info on this spreadsheet. Also, please retweet. #Ukraine #AcademicChatter #ScienceTwitter docs.google.com/spreadsheets/d…

Happy to (belatedly) welcome Dr. Alex Phillips @alexploring to the lab. Her previous work on organic sulfur at Caltech is a great match for this postdoctoral project, which looks into the unappreciated role of orgS in low-sulfate environments. @UmdLLO @UMDSwenson

News brief: The spread of quagga mussels across the American Great Lakes has transformed the supply of phosphorus - a key biological nutrient - to the ecosystem, according to research published this week in PNAS. twin-cities.umn.edu/news-events/in…

Our new paper in PNAS describes the big effects of tiny invasive mussels, with implications for nutrient management in the Great Lakes pnas.org/content/118/6/… @JIYLi @UmdLLO @UMDSwenson

I wrote this piece two days ago, to help non-specialists understand the exponent of the virus and what the quarantine could do. sereshka.livejournal.com/93000.html It already requires an update, but may be still useful if you struggle to explain to people what we are trying to avoid.
