After five incredibly happy years at Macalester, I recently moved to Chapman University. I am incredibly grateful to Macalester for my time there, and I am the scientist and person I am today because of the wonderful mentorship and inspiring student, staff and faculty community!

[Christine Sierra O'Connell, PhD @csoconn]

Thank you, Mac, for everything. ❤️

Meanwhile, I have not posted on Twitter in several years, and am going to continue to be inactive on this platform. I have a profile under the same username at Bluesky and may be slightly more active there. But I am updating my affiliation above.

Poking my head up during sabbatical to (very late on) highlight a neat paper I collaborated on and led by Maya Almaraz (not on Twitter), with @whendeesilver @lesterlin @StephenPorder @PeterGroffman. Yay!

Nitrogen changes from insulating greenhouse gas forms to inert forms called dinitrogen as it moves between soil, air, and life. Scientists now have discovered that soils emit more nitrogen in its inert form than previously thought.

For those interested in comparing ecosystem responses to drought across sites that differ in climate/productivity... this analysis will be useful. Nice work.

This is Anasco Puerto Rico #fiona #CBSnews we just landed here.

[Angélica Serrano-Román @angelicaserran0]

“At least Fiona isn't like Hurricane María.” Puerto Rico was left without electricity. Thousands still live in damaged houses covered with blue tarps. People are worried. Judging by the videos, some would lose their homes. Five years later, Puerto Rico still hasn't recovered.

if you want to support Puerto Ricans in the aftermath of hurricane Fiona DIRECTLY:

here's a thread of local organizations (don't donate to the red cross)

[❤️‍🔥 @stellarislunvr]

I want to remind everyone especially in the US that Hurricane Fiona has also made landfall in the Dominican Republic as well as the Virgin Islands. A lot of the times I feel PR is very central to news coverage of these disasters, but the Caribbean in whole will need assistance.

[Tana Wood @Tana_TropicsGal]

And it only took a newly formed Cat 1 Hurricane!!! Nothing near Maria. Zero lessons learned it seems.

@KateBrauman I’m so sorry to hear this, Kate! I’ll be thinking of you and both of your parents. ❤️❤️❤️

[Christine Sierra O'Connell, PhD @csoconn]

@KateHelmstedt @QUTDataScience @QUT Yayyyyy!!!!! 🥳🥳🥳 So well deserved!!
