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. โ๏ธ๐งช

New paper by Francisca Nรบรฑez 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.
