I'm teaching a scientific writing course and figuring out how to talk about effective use of AI writing tools. I was interested to see ChatGPT's response about its weaknesses. Do other people have effective activities for talking about ethical LLM use with undergraduates?

Just got back from a week of work on the lake-terminating Gilkey Glacier near Juneau #Alaska. A quick summary of data collected and some initial results:

Excited that Noah Caldwell's work is officially out in @igsoc.bsky.social Journal of Glaciology! Noah used satellite remote sensing to estimate how much ice is being lost to iceberg calving and subaqueous melt on 55 Alaska lake-terminating glaciers. Read more: doi.org/10.1017/jog....

I’m thinking we should spread this news about the firings at NOAA as far and wide as possible. Like cancer research, weather forecasting seems likely to be broadly popular across the political spectrum. apnews.com/article/nati...
Hundreds of weather forecasters fired in latest wave of DOGE cuts
Federal workers who were not let go said the afternoon layoffs included meteorologists who do crucial local forecasts in National Weather Service offices across the U.S.

Why does science need government funding?
What are the impacts to the US of cutting polar science?

N.S.F. Cuts Raise Fears of a Reduced U.S. Presence in Polar Regions
The National Science Foundation has fired workers at the office that manages polar research, raising fears about a reduced U.S. presence in two strategic regions.

Very proud to see Lily Vowels' senior thesis work published in #Geomorphology! Lily used #Landsat imagery to investigate how suspended sediment in #Alaska glacier-fed rivers has changed over the last ~40 years as #glaciers have retreated and terminal #lakes have formed and grown 🧪

GPS enthusiasts - has anyone ever seen behavior where a station non-physically jumps positions back & forth between epochs? The jumps are 10-100 cm in scale, the data were processed via NRCan PPP, it’s a Trimble NetRS receiver sampling every 15 s installed on a glacier in the Canadian Rockies
