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/...

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.

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.

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.

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.
