New #NSF GRFP removed 2nd year student eligibility

Narrows the pipeline to the point of choking opportunities for all but a few
danielbolnick.bsky.social
The GRFP announcement from NSF cuts out an entire cohort of 2nd year students from consideration, without warning. This is so deeply unfair that it warrants a formal protest from the scientific community. If someone wants to work with me to craft an open letter and solicit signatures, LMK.

New: After a long wait, the GRFP solicitation is live! Deadlines have been extended to early November, so applicants have a bit over a month to submit. www.nsf.gov/funding/oppo...

That’s why I was thinking stiff soils would be the best bet. Greater difference in impedence? Full root masses would easily meet the 0.5 m criteria
happygeojill.bsky.social
The problem would be getting a clear signature with multiple generation of trees - so maybe (total hand waving here) best chance would be in recently deglaciated areas- with soil developing.

I'm not a shallow geophysics person at all so take this all with a grain of salt- it will depend on what kind of resolution you could get with the seismology but in stiff clays I would expect you could see some vertical compression from trees in the wind. Even better in compact frozen soils.

@moreorloess.bsky.social thanks for the shout out- and beating me to the answers 🎄. @andydoggerbank.bsky.social - we were just talking about something similar at a paleoseismic site -methinks it would be hard to distinguish frost heave/mixing from trees in the paleo-record depending on the soil age

So the old guard rules. Sorry about your and Adam's session.

I also am for a name change - and the survey when I was on the social media committee. I saw the survey but never saw the results. I also feel like the division doesn't really have a way of engaging students in the same way that AGU EPSP does - despite trying.

Is that all there is? Well - how did I get here?
Hope to see you at KITP 2026

That's part of the study! A few studies (mainly out of France) have suggested forests may be seismic meta materials - and pointing to characteristics similar to old growth PNW forest- is it root network? roots and trunks? (we know that trees damp wind through branch structure).is it real?
happygeojill.bsky.social
Can forests damp earthquake waves and thus limit co-seismic landslides? What does this mean for Critical Zone development? Postdoctoral position with Will Struble and a multi-disciplinary team (including me🌲🌲🌊🌳🪾). Position is open until filled.

For those who 💙 OR landscapes + lidar... here is a link to desktop images produced by the geomorphology/lidar folks at OR's state mapping service (and so much more!). I have no involvement w/the project - just thought some might enjoy the science scenery. www.oregon.gov/dogami/pubs/...
