Check out our paper that came out in @science.org today. It uses some really cool experiments to explore the rheology of temperate ice. We find that contrary to colder ice this warm ice has a value of n=1!!

Linear-viscous flow of temperate ice
Accurately modeling the deformation of temperate glacier ice, which is at its pressure-melting temperature and contains liquid water at grain boundaries, is essential for predicting ice sheet discharg...

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....
