Deep glacial troughs and stabilizing ridges unveiled beneath the margins of the Antarctic ice sheet

A high-resolution update of Antarctic bed topography using mass conservation reveals broad stabilizing ridges for glaciers flowing across the Transantarctic Mountains, and stabilizing slopes beneath Moscow University, Totten and Lambert glacier system.

An ancient river landscape preserved beneath the East Antarctic Ice Sheet

Using satellite and survey data, an ancient river landscape 300 km wide has been discovered buried and preserved beneath the ice in East Antarctica. It has likely survived largely intact for up to 34 million years since before ice sheet growth.

On-shelf circulation of warm water toward the Totten Ice Shelf in East Antarctica

The Totten Glacier in East Antarctica is grounded below sea level and vulnerable to ocean forcing. Observations and simulations demonstrate warm water access from offshore to the glacier, facilitated by deep topography off the Sabrina Coast.

Steep reverse bed slope at the grounding line of the Weddell Sea sector in West Antarctica

The bed of the West Antarctic ice sheet is, in places, more than 1.5 km below sea level. Radio-echo sounding data from the Weddell Sea sector of Antarctica reveal a large subglacial basin immediately upstream of the ice sheet’s grounding line, with a steep reverse gradient and a smooth floor.

Seismic detection of an active subglacial magmatic complex in Marie Byrd Land, Antarctica

Several volcanoes exist in Marie Byrd Land, a highland range in West Antarctica, but none were thought to be currently active. Analysis of seismic data from the region shows that magma could be moving beneath the West Antarctic Ice Sheet, with potential implications for ice flow.

Initiation and long-term instability of the East Antarctic Ice Sheet

Geophysical and geological data reveal increased ice-sheet variability and surface meltwater—possibly analogous to future conditions—offshore of the Aurora subglacial basin of East Antarctica during warm climate intervals of the past 50 million years.
