@mrillig I think it is reasonable to send samples out for routine and time-consuming analysis. My idea is that one student should must one skill, know everything about it, and that is enough. Save time for more important questions, don't learn too many skills.

Do-it-yourself in labs or farming things out? Should we do as much as possible in our labs or send samples to companies for analysis? What do you think…. open.substack.com/pub/matthiasri…

If you are: • European national, under 45, Hold a PhD + full-time position in a European university/research institute, interested in 2-year collaborative visits to China (≥30 days per year, 2027–2028)

Any European early-career environmental scientists want to visit China? I’m looking for strong candidates with complementary research interests in AI+Soils and AI to co-apply. NSFC Invitational Visiting Fellowship for European Scholars (IVFES) 2026!

@The_InnovationJ @Innov_Geosci Glad to publish our recent finding in Innovation Geoscience. The floating iron plaque, a new hotspot for methane oxidation.

New in The Innovation Geoscience! Floating iron biofilms as hidden barriers to methane emissions in wetlands. This study identifies floating iron biofilms at the water–air interfaces as a critical and previously overlooked methane-barrier in wetlands.

@MikePeacock86 Really hope I was there

Another science-packed day at #EGU2024. My highlight was Euan Nisbet's interesting (but depressing/scary) talk: "Methane’s record rise 2020-2023: likely causes, impacts and consequences" meetingorganizer.copernicus.org/EGU24/EGU24-12…

@DrBenRunkle It seems my PhD student fits it well, forwarded

Hi scientists, are there any good practices or protocols to manage data from different groups in a big project?

@eLife @KAWstiftelsen @BristolUniLib I believe reviewed preprints is the future of scientific communication.

Did you know that the Knut and Alice Wallenberg Foundation (@KAWstiftelsen) and @BristolUniLib services are embracing reviewed preprints as an alternative way to assess researchers? Find out more about the support surrounding our publishing model: elifesciences.org/inside-elife/e…

Please consider submitting a paper on CECs such as PFAS, Microplastics, Pharmaceuticals, Personal Care Products, or other contaminants of emerging concern! SEH is an excellent journal with a great editorial board. #CEC #pollution #crop #soil

@MikePeacock86 We measured paddy soil porewater with rizon sampler, there is methane. But I don't trust the value.

A question measured dissolved GHG people. Is there any value in taking CH4 measurements from water samples that have been collected, filtered and stored cold (without headspace). Or will all the CH4 have degassed during filtering/been eaten by methanotrophs?

@goldschmidt2023 Thank you very much. I didn't know Goldschmidt had the program, and it is really a great opportunity for my student. I already forward it to her.

@ebiogeochem Has she considered signing up for the @goldschmidt2023 mentor programme, this could be helpful to guide her through her first Goldschmidt? More info here: conf.goldschmidt.info/goldschmidt/20…

My PhD student will attend @goldschmidt2023 from China alone, and it is the first time for her to go abroad. If anyone wants to make a friend with her, please drop a msg and I will let you connect. Thank you

@lesterlin Why dont use glass fibre membrane

I am surprised by how much dissolved carbon can be leached from Whatman 42 filter papers. My group detected 9 to 11 mg C/L after running ultrapure water through them. In contrast, our soil samples typically result in 30 to 60 mg C/L.

@tylerleeanthony It seems there are typos in the Y-axis titles for Fig.1 a and c

Check out our new paper in Nature Communications! nature.com/articles/s4146… I collected four years of continuous GHG fluxes to quantify importance hot moments of N2O emissions from continuous alfalfa agriculture. < 1% of measurements accounted for up to 57% of annual emissions!
