Lauren Andrews and I caught up in January 2024 when she visited Dartmouth to give an ice+climate seminar as well as work on an ICESat-2 collaborative project.

Much of conversation focused around subglacial hydrology, the flow of water under glaciers and ice sheets. In particular, we discuss the field campaign that she worked on as a graduate student. The result of this fieldwork was published in her 2014 Nature paper. 

A few names of folks that appear numerous times throughout the show are

• Bob Hawley, Dartmouth College
• Martin (Tinu) Lüthi, University of Zurich
• Matt Hoffman, Los Alamos National Laboratory

I also mention the borehole catalog that I am compiling. In this project, I am collecting borehole observations of subglacial effective pressure (the difference between ice overburden and water pressure). The goal is to understand the distribution of effective pressure below glaciers (figures 1 and 2) and to constrain subglacial hydrology models. The data catalog is stored as a google sheet: please be in touch if you have data to add to the catalog!
