Congratulations to @winnie-polargeo.bsky.social for earning an NSF CAREER grant to map temperatures at the base of the Antarctic ice sheet — the first project of its kind. This research will refine climate models and help predict future melt, protecting coastal communities. b.gatech.edu/3LyaveA

The bathymetry of eastern Lake Superior, the part that would be crossed by an ore carrier coming from the NW, trying to make Whitefish Bay in a storm, is fascinating. I have heard those N-S troughs explained as subglacially eroded tunnel channels, but there are probably other ideas out there.

New video: A glacier on Antarctica’s Eastern Peninsula experienced the fastest retreat recorded in modern history—in just two months, nearly 50 percent of the glacier disintegrated. Watch this video to understand what happened. Study by @ciresnews #Antarctica #glaciermelt

Lovely to receive the first copies of my new book, "Life on a Little-Known Planet." Thanks to www.evangaffneydesign.com for the great cover design.

New paper by Chelsea Volpano where she characterizes the role of landfast ice on coastal sediment transport. interesting nonmonotonic response in sediment transport with the termination depth, explaining much of the erosive vs protective debate of ice agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Check out this time-lapse video of waves eroding an ice front from an experiment conducted in our cryogenic wave tank at the University of Wisconsin-Madison. The tank is housed in a walk-in freezer, and the waves are precisely controlled. This video captures about an hour of wave erosion.

If you're interested in Glacial Geology/Geomorphology consider submitting an abstract to our GSA session "T182. Recent Advances in Glacial Geology, Geomorphology, and Chronology": Deadline for abstract submission is August 5. @geosociety.bsky.social.

This gets far less attention than the Trump administration's attack on Harvard, Columbia, etc. but the GOP is also slashing funding for tribal colleges and universities, with devastating effect. apnews.com/article/trum...

👏🏽 Congrats to INSTAAR alum Peter Clark for being elected to the National Academy of Sciences! He's a professor @osuceoas.bsky.social & specializes in glaciers, ice sheets, sea level, & paleoclimatology. His INSTAAR advisor was John Andrews. Nice 2016 video on Peter: www.youtube.com/watch?v=Tjve...

It’s important that all Americans realise what things would be like #withoutNSF This is your National Science Foundation that pays for scientific research and brought you things that you use and rely on in your daily lives. Without it, we will crumble as a nation. www.nsf.gov/impacts

New paper by @geonatasha.bsky.social where ice was slid atop sediment at a constant velocity but where effective stress, N, was transiently varied and drag measured. Important finding of hysteresis in the system, which was stronger on N unloading! agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Interested in subglacial landforms and sediment deformation? Tomorrow is your day at #EGU2025 . First a talk by @lzoet.bsky.social & Schlegel in GM9.4 and then head over to see Schlegel & @lzoet.bsky.social in PICO CR6.2

Waves through brash ice on Lake Monona. Makes a great sound as the ice bits clang around.

Calling all Oceanography & Atmospheric Sci. professors! Let's teach our students the many & varied ways that the services that NOAA provides impacts their lives.

Nice ice shove on Lake Monona

Not seeing a lot of discussion about this. Some researchers have estimated the Glen's flow law exponent n as ~ 1 rather than 3-4 for temperate ice. This could mean that the world's most critical glaciers are linear-viscous are their base. 🥼❄️ ⚒️ www.science.org/doi/10.1126/...

Is there a more impressive drumlinized landscape than this? Between Columbus and Beaver Dam, Wisconsin. Green Bay Lobe of the Laurentide Ice Sheet. Sentinel 2, Jan 9, 2025, and 1 m lidar. Smaller squares in image are 1/2 X 1/2 mile. US Hwy 151 runs almost parallel to ice flow here.

Very privileged and thankful to have been involved in this research, check out our results!

Check out our paper that came out in @science.org today. It uses some really cool experiments to explore the rheology of temperate ice. We find that contrary to colder ice this warm ice has a value of n=1!! www.science.org/doi/10.1126/...

HUGE congratulations to the friendliest guy in glaciology, Dr Richard Alley! @igsoc.bsky.social 🧪⚒️❄️ www.whitehouse.gov/briefing-roo...

The reality is that the last 10 years are globally both the warmest in the Observational record and almost certainly the warmest since the peak of the last interglacial period, more than 125,000 years ago.

New paper by Francisca Núñez Ferreira that among other findings develops a method to use the sediments in esker deposits to inform on the subglacial effective pressure gradient and how it changed in space/time. We find that eskers largely form at the margin. onlinelibrary.wiley.com/doi/10.1002/...
