#TopographyTuesday | For decades, Antarctica’s interior remained one of the last blank spaces on Earth’s maps. Beneath ice up to 4 kilometers thick lies a rugged landscape of buried mountain ranges, deep valleys, marine basins, and hundreds of subglacial lakes.

Sources of oceanic and volcanic heat melting a subglacial channel in Kamb Ice Stream, West Antarctica Melting from oceanic heat and basal lubrication from subglacial freshwater are fundamental elements of West Antarctic Ice Sheet mass balance that are poorly constrained. The ice streams feeding the Ro...

Scientists Identify 85 New Active Subglacial Lakes in Antarctica

Using CryoSat-2 data (2010-2020), researchers found 85 new active subglacial lakes in Antarctica, raising the known total to 231. The study was published Sep 19 2025. Read more: getnews.me/scientists-identify-85-n... #antarctica #cryosat2 #subglacial

New Antarctic Subglacial Lakes Reveal Hidden Impact on Sea Levels

Scientists using ESA's CryoSat data (2010‑2020) identified 85 new subglacial lakes beneath Antarctica, raising the known active count to 231 and revealing 12 fill‑drain events. getnews.me/new-antarctic-subglacial... #antarctica #subglacial #cryosat

Using a hot-water drill, the team accessed a channel at the grounding zone of West Antarctica’s Kamb Ice Stream. For the first time, they directly observed #subglacial #water entering an ocean cavity, revealing a turbid plume and signs of major ice melt and sediment movement.

Modelling subglacial fluvial sediment transport with a graph-based model, Graphical Subglacial Sediment Transport (GraphSSeT) Abstract. A quantitative understanding of how sediment discharge from subglacial fluvial systems varies in response to glaciohydrological conditions is essential for understanding marine systems aroun...

🚨 Paper alert! New research co-authored by #VAW member Mauro Werder introduces GraphSSeT, a model that advances #subglacial #sediment #transport analysis by simulating sediment discharge dynamics, grain size transport, and hydrology interactions.
