Thanks to @earthscope.org for making the archiving process easy, and facilitating the reuse of hard-won, tax-payer funded data collection.
Here's a look at the glaciohydraulic tremor amplitude over the course of the melt season, from a paper soon to be (re-)submitted. If you have any interest in glacier seismology, or know someone who does, I hope you'll spread the word!
I'd love to have more science come out of this dataset
I'm very pleased to have publically archived what I think is an exceptional seismic data set. 5 months from 8 stations on the ablation area of the West Greenland ice sheet, NE of Ilulissat. Very good data quality and uptime spanning the entirety of the ablation season.

At this field area, downstream of McCarthy, Alaska, we can go and touch these overridden sediments and study them with as much detail as we wish. More commonly, these sediments are only accessible as a cm-scale core or via low resolution geophysical surveys.
Then, imagine my surprise when we learned that two complete glacial cycles were preserved in the sediment below! These predate the LGM and extend back probably close to 100 ka
I still find it mind boggling that in one of my favorite places, in Alaska, we can walk along on the bed of an ancient, water-terminating ice stream, just as we might find in Antarctica or Greenland. onlinelibrary.wiley.com/doi/10.1111/...
cool- thanks! I hadn't seen that one. So perhaps if the present ACC temperatures are a transient warming, which then passes, then they can all recover..?
(with the provision that the models all are simulating key physics sufficiently)
Glaciologists-
are you aware of any literature in the last couple decades that finds Thwaites to be in a stable setting? Or even that it might not collapse?
I'm not sure why we keep writing that "Thwaites Glacier _might_ collapse"
Can we just all cut to the chase?
A local journalist reached out to ask about regional glacier change- one of the first places I checked was maps.theia-land.fr, a really super, interactive resource, hidden within Hugonnet et al., 2021, www.nature.com/articles/s41....
This is some bullshit
“The NSF polar office has awarded 88 percent less money in grants this year.”
This would take standard ~10% funding rates down to 1%.
No wonder my program officer was forbidden from telling me the funding rate after we were rejected www.nytimes.com/interactive/...
My wife hears Richard Alley giving kickoff plenary at an IPY meeting, and comes down the hall to ask "Who is _this_? This person is a delight!"
Talk about generational talent...
But I guess, if the main point is that "it's complicated," it's a small wonder that I hadn't yet encountered this essay. Where's the fist shaking?!
Here's the glacier intervention article that I wish everyone would lead with: eos.org/opinions/gla...
Neither in thrall to the wonders of Antarctica nor absolutist in opposition, the authors illuminate the middle way and finally get right the fact that there are many many complicated considerations
Although in retrospect, I realize part of the reason this was so popular is that it was a break from otherwise wall-to-wall covid coverage.
For more bewildering coverage of the highest impact work I’ll ever do, I tried to track it here: tbartholomaus.org/media/#:~:te....
Ahhh…. a simpler time…
Hearing all the trump news makes me think of a grad student who’s sending me a new draft manuscript every 4 hrs, with the note, “New version! Ignore the last one. Give me feedback on this one ASAP.”
Have you gotten any reviews back recently? Anything out of the ordinary?
I remain committed to my work of understanding glacier behavior, in order to empower community responses to catastrophic flooding. But I'm not sure how to proceed in this mix of not enough and too much information
Did we get sunk by the Trump Administration's mandated dragnet? www.washingtonpost.com/science/2025...
Or again, maybe we just fell short of an already competitive review environment- certainly neither proposal was perfect!
Any other recent experiences NSF experiences out there I can compare with?
There were glacier proposals, and according to 2024 best practice and current NSF guidance (www.nsf.gov/funding/lear...), we wrote "The team is dedicated to increasing diversity, equity, and inclusion in cryospheric science"
I've just had two resubmitted proposals rejected by NSF's Arctic Natural Sciences. One had only two reviews (E and VG) w/o a panel summary, and one had a short note from a program officer (stating that reviews were attached) but without any kind of peer review whatsoever. Unlucky? Or NSF in 2025?
Congratulations!
The @uidaho.bsky.social Dept of Civil and Enviro Engineering is hiring a Geological Engineer! Open until filled.
I highly recommend both the Univ of Idaho, and life in Moscow, ID. Excellent research and teaching support, stellar quality of life.

Ice sheet loss leads to coastal flooding- now and in the future.
Unfortunately, ice sheet modelling groups haven't been empowered to reproduce observed ice sheet changes in a way that is necessary to have confidence in projections.
See my #AGU24 presentation here:

This is cool. I also can't help but watch and try to deconvolve EOFs in my head
Be in touch if you have questions or want to discuss more.
The first step to addressing this problem is identifying and communicating the problem.
This problem stems from the novelty of the research in this area and the legacy view of ice sheet modeling as an academic curiosity. Now that there is a clear applied need for ice sheet modeling to inform coastal planning, there needs to be a funding program to meet this need.
Because the simulations of observed ice sheet change are so flawed, the projections of sea level rise are likely flawed similarly. This means the funding going towards protecting coastal communities is potentially misallocated- it may not provide the level of protection for which its designed.

I created a starter pack on "Sea level change and coastal erosion". If you think I should add other people, please let me know. 7/x
