Description
Melting ice unloads the crust, and beneath West Antarctica that crust hides restless magma. Coonin and five co-authors model in 2024 how a magma chamber answers a shrinking ice sheet, thinning the load in a thermomechanical simulation of the rift system below. Andes dates hint that ice and eruptions have fed each other before.
Unloading deepens where rock melts and reshapes the stress that opens or traps dikes. Inside the chamber, the pace of unloading changed how much magma eventually erupted and how much heat reached the ice. The authors frame the loop as a missing term in sea level forecasts. In Antarctica, they show, the ice sheet and the volcanoes negotiate.
