Glaciers in California’s Sierra Nevada are likely disappearing for the first time in the Holocene The projected loss of glaciers in California’s Sierra Nevada is likely unprecedented in at least the past 30,000 years.

Very cool work (with a very sobering result) led by Andy Jones (a paleoCAMP alumnus!) in Science Advances: 'Glaciers in California’s Sierra Nevada are likely disappearing for the first time in the Holocene' www.science.org/doi/10.1126/...

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/...

This one is freshwater, but we've built it to do saltwater too. We can measure the temp everywhere by moving the probe around, but I think we'll build thermistor strings to measure temp in several places at once.

just under an hour

water temp was ~0.5 C

we actually made some pressurized bubbles on accident during a test run and it definitely made a difference

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.

White House budget request slashes funding for tribal colleges and universities If President Donald Trump's budget proposal wins final congressional approval, funding will be slashed for tribal colleges and universities.

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.

Peter Clark

👏🏽 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...

NSF Impacts NSF's mission is to advance the progress of science, a mission accomplished by funding proposals for research and education made by scientists, engineers, and educators from across the country.

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/...

Layoffs hit federal climate, weather agency NOAA The cuts could affect NOAA's weather forecasts, climate research and other functions.

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