Antarctic lakes (above and beneath the ice sheet): Analogues for Mars [PDF]

The perennial ice covered lakes of the Antarctic are considered to be excellent analogues to lakes that once existed on Mars. Field studies of ice covered lakes, paleolakes, and polar beaches were conducted in the Bunger Hills Oasis, Eastern Antarctica ...

Ice Sheets Without Dynamic Topography

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Dynamic topography results in uplift and subsidence events on Earth's surface with amplitudes on the order of a kilometer. These vertical motions are known to have influenced ice sheet evolution, but how dynamic topography has controlled the current state of present ice sheets is unknown.

Quantifying the feedback between Antarctic meltwater release and subsurface Southern Ocean warming [PDF]

Earth System Dynamics
The subsurface ocean around Antarctica is one of the primary drivers of mass loss from the Antarctic ice sheet through the basal melting of ice shelves.

Coupled Ice Sheet Structure and Bedrock Geology in the Deep Interior of East Antarctica: Results From Dome A and the South Pole Basin

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract The deep interior of the East Antarctic Ice sheet likely contains important records of climate and ice sheet evolution. Here we report on a recent aerogeophysical survey of the southern flank of Dome A, over South Pole Basin. We find an extensive radioglaciologically defined basal unit under Dome A that abruptly truncates within South Pole ...

Seismic Evidence for Widespread Active Magmatism in Eastern Marie Byrd Land, Antarctica

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Marie Byrd Land is a volcanically active province that overlaps with the Amundsen Sea Embayment, a region of the West Antarctic Ice Sheet that is experiencing particularly rapid ice mass loss. We locate 34 previously undetected seismic events (ML 1.2–3.2) and identify 251 additional similar events from 2019 to 2024 in eastern Marie Byrd Land ...
