The thought police...NSF now canceling (aka archiving) its premier climate change research program 'cause Trump and the DOGE bros think it'll make climate change go away? Good luck with that. ❄️🧪 #scicomm #climate #science  🌎 🔬 ⚒️ #geosky #ClimateHealth #ClimateAction www.nsf.gov/funding/oppo...

👏🏽 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...

Abstract. A polar jet stream (PJS) split by the Laurentide Ice Sheet (LIS) is a well-established feature of Ice-Age atmospheric circulation. California’s central Sierra Nevada Mountains (37–38° N) lie...

Applications close on Wednesday (the 19th)! One field season in the (partially) buried mountains of SE Greenland is definitely on the cards. Just have to decide if it's a 300 meter core at red, blue or purple...

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/...

Subglacial hydrology insights from eskers developed atop soft beds of the Laurentide ice sheet
A new method was developed for estimating aspects of the subglacial hydraulic system based on sediments deposited within Eskers. It shows negative basal effective pressure gradients and temporal vari....
