Speaking now Cody Sheik on Laurentian Great Lakes & Nfix - where is the increased NO3 coming from? Maybe Nfix! [N] not a master regulator of N fix rates. Read more here: sciencedirect.com/science/articl…

Now talking Sam Wilson - now at New Castle University. Using H based measurements to measure Nfix. Replace N2 with Argon and measure H. read more here: onlinelibrary.wiley.com/doi/full/10.11… #Nfixrules #AGU21

Now into the deep sea with Anne Dekas - does Nfix happen widely in deep sea sediments? gene says VERY widely & phylogenetically diverse! yet rates not detectable. Paper in prep! #Nfix #AGU21

Last talk of our session Saroj Poudel - looking at global nitrogenase distribution. #Nfixrules #AGU21

Our first working group is off and running! RCO1 Focusing on Rates, Drivers and Biodiversity of N Fixation across Aquatic Habitats had a second kickoff meeting today - now, groups will start data gathering in prep for a Workshop in June. #NSFfunded #RCN U.S. National Science Foundation

Please RT: The Aquatic Nitrogen Fixation RCN is searching for a Postdoctoral Researcher to coordinate working group activities, participate in syntheses and lead publications. More info @ the website aquaticnfixation.com/news.html or contact @AmyMarcarelli @ScottBiogeochem Fulweiler Lab

We are getting ready for the first RCN workshop starting tomorrow on N fixation drives and diversity across aquatic habitats. PIs Fulweiler Lab @AmyMarcarelli @ScottBiogeochem, together in the SAME ROOM for the first time since way before the start of the project!

Room is ready!! First in person workshop for working group 1. So excited for the next two days! #nfixrules U.S. National Science Foundation #wevegotannfix

This morning we discussed rates of nfixation across the aquascape! our workshop includes students, postdocs, professors, govt scientists, multiple countries. So fun to here all the ideas #nfixrules #wevegotannfix thanks U.S. National Science Foundation for the funding

Lunch break! This crew has been working hard - chasing down methods, conceptualizing figures, cleaning data. #wevegotannfix #nfixrules

Spread the word - we are hiring a research associate - details here: aquaticnfixation.com/news.html This is a fun, dynamic, active group working on the best N process out there! 😄

Love nitrogen? Want to be in an awesome lab helping conduct cutting edge research on SGD? Check out the Knapp Lab at Florida State as they are hiring a Professional Research Assistant myweb.fsu.edu/anknapp/

We are excited to see the first paper in our special issue in Biogeochemistry is available: link.springer.com/article/10.100…

Our Suzanne Cory Medal recipient Prof Catherine Lovelock FAA is a global expert on how coastal ecosystems impact—& are impacted by—climate change. With most Australians living close to the ocean, it's not just fisheries that depend on healthy coastlines.

We're now accepting applications for our second working group! Interested in stoichiometric drivers and constraints on N2-fixation in aquatic ecosystems? Apply here: forms.gle/L8UEaQvn1oA9EG… Applications due April 14.

There's still time to apply for our second ANF-RCN working group! If you're interested in the stoichiometry of nitrogen fixation in aquatic ecosystems, apply here: forms.gle/gd1XxZhCeqsrjK… Applications due this Friday, April 14!

Working Group 2 Workshop: stoichometry of nitrogen fixation begins! U.S. National Science Foundation #wevegotaNfixation

This morning we talked about many different aspects of nitrogen fixation! #wevegotanNfix

we talked about different types of nitrogen fixation and how we might model these different groups! U.S. National Science Foundation

we had lots of good discussion, exciting ideas, and new model approaches! U.S. National Science Foundation #wevegotanNfixation
