Decoupling of N2O Production and Emissions in the Northern Indian Ocean
N2 ${\mathrm{N}}_{2}$O emissions are largely fueled by nitrification (∼ ${\sim} $57%), followed by denitrification (∼ ${\sim} $30%) and transport from remote regions About 74% of N2 ${\mathrm{N}}...

I wanna make a consolidated mini series on soils biogeochem, with like just the barest amount of ochem that matters, for gardeners. If someone could come up with a cute name for that project that would be great, thank you. Travis says I should do beginner stuff like: what is soil? But idk. Thoughts?

Research topics are flexible but should at least broadly incorporate questions related to how microbial death pathways influence soil microbial community composition and function.

A bit of #fieldwork nostaligia trip today
On 12 March 1998 4 of us (3 from @AWI_Media & me from @sos_bangor_uni ) had just finished a remarkable remote field camp at Drescher Inlet #Antarctica
Including a rudimentary but effective #biogeochem lab. Our Doc was the vet!

pressure in some areas has changed, so, say what does the biogeochem/physics reasonably predict about that given the changes to depth there? I’ve looked for recent articles on it but everything is pretty wooly.
I know about the freezer and pot lid theory that supposedly holds clathates in. Does

recall correctly, we also covered ecosystem structure & function effects of herbivory more in biogeography & biogeochem classes, like through effects on carbon cycling as a result of beavers affecting wetlands.

I am very jealous of this trip.
Etah, Greenland is further north than Thule Air Base! There's basically no biogeochem data on Arctic Data Center from that area (yes I did look)!
Rusty is a very good travel writer, excited to read all about whats sure to be an amazing expedition

I’m going kayaking in the Arctic and the whole trip hinges, in part, on whether the local narwhal hunters are too busy for us.

Biogeochem folks, I'm setting up a lab! We have old Nalgene containers that I'm using for an acid bath and Ultrapure water storage, and its...unclear what they were last used for.
What would be the best way to clean them? I was thinking citranox, rinse, 10% HCl soak, rinse, then should be ok?

Excited to share that I just started a new position as a Senior Editor of biogeochem at Nature Communications 🥳
This move out of academia will still allow me to attend conferences and stay close with my colleagues ❤️
So ready for this next chapter!
