Here are a few pics from a field trip to Gothic, CO last week! Lots of neat instruments, great discussion, and beautiful scenery. A big thanks to PB from Nebraska, @deboerg, and Joe for planning and leading this. And thanks to @SMaltarich from CIRES for joining the adventure!

❄️Full Waveform Inversion to model firn AND ice slabs? ❄️ Have a look at my paper: cambridge.org/core/journals/… If you use seismic data in glaciology, consider FWI in the future! But don't let me tell you what to do, read the paper and decide yourself!

🚨 My first, first-author paper has been published in The Cryosphere! ❄️ Co-authors Nander Wever, Max Stevens, Jan Lenaerts, Brooke Medley, and I evaluated and compared two firn models on the Greenland Ice Sheet. Check out what we found here: tc.copernicus.org/articles/17/21…

New research article: An evaluation of a physics-based firn model and a semi-empirical firn model across the Greenland Ice Sheet (1980–2020) doi.org/10.5194/tc-17-…

Impressive change of possibly my favorite glacier. You can see both retreat and thinning! 🚨

Out today! Our new study in #AGUpubs: “Quantifying Antarctic-Wide Ice-Shelf Surface Melt Volume Using Microwave and Firn Model Data: 1980 to 2021” agupubs.onlinelibrary.wiley.com/doi/full/10.10… W/ co-authors N Wever, @DevonDunmire & @gsnowph CIRES National Snow and Ice Data Center CU Boulder College of Arts and Sciences AGU Cryosphere Protect Our Winters

Antarctic ice shelves experienced only minor changes in surface melt since 1980, according to a new CIRES/CU Boulder 🦬-led assessment. But the authors of the paper expect melt to increase in the coming decades. Read the story: cires.colorado.edu/news/antarctic…

In a very wholesome moment at our research group dinner yesterday, we reminisced about the best #clouds ☁️ we'd ever seen. In case anyone's wondering, these are my top 3 📷 🔥 pyrocumulus in Colorado, 🛸 lenticular on Mt. Rainier, & 🏔️ a perfect band of clouds on the Tetons

Ever wondered why the edges of floating ice tongues look feathered? Check out this paper by Tim Bartholomaus's former PhD student Chris Miele: agupubs.onlinelibrary.wiley.com/doi/10.1029/20… Chris used the icepack model (icepack.github.io) to show loss of side friction causes extension & rifting!

Croc spotted at Sweitzer Lake State Park 👀👀👀 Be careful on the water this weekend folks!

'tis the season of automatic email replies making me very jealous of everyone's summer field work

For this week’s #HumansOfCIRES, meet Megan Thompson-Munson, a PhD student ATOC at CU-Boulder. Megan uses models to study how climate change affects the #Greenland Ice Sheet, and her favorite food is apple pie w/ extra-sharp cheddar cheese! Read the interview: bit.ly/HOC_Thompson-M…

New preprint in TC on our work developing high-resolution maps of grain size and ice layer stratigraphy in firn cores! Check it out to see more about the method, dataset, and an application of these maps to document firn structure changes after extreme melt. Feedback is welcome!

📢 Exciting Announcement! The firn Symposium's review paper is out in Nature Reviews Earth & Environment 🌈, shedding light on the crucial role of firn in Greenland and Antarctic ice sheets 🏔️❄️ 🌊 [1/n]. 📰 doi.org/10.1038/s43017… [Behind 💰-🧱, so DM if you want a copy]

👏👏👏Congratulations to Megan Thompson-Munson for winning OSPA AGU (American Geophysical Union) 2023!!

Check out our new paper! And please enjoy this great write-up on it in CIRES: cires.colorado.edu/news/warming-h…

A new CIRES and INSTAAR 🏳️‍🌈-led study found Greenland's "firn" - the spongy layer between ice and snow - is more sensitive to warming than cooling. The paper was led by CIRES and CU Boulder 🦬 PhD graduate Megan Thompson-Munson and CIRES Fellow PB from Nebraska Read the story: cires.colorado.edu/news/warming-h…
