Digital Twins of the Polar Regions
Read more of: Digital Twins of the Polar RegionsThis project is developing digital twins of Antarctic and Arctic environments and resources. A digital twin makes it possible to test “what if” questions far more quickly than traditional computer models.

Melting at Thwaites Grounding Zone and its Control on Sea Level
Read more of: Melting at Thwaites Grounding Zone and its Control on Sea LevelMELT is an ice-based project that will use autonomous sensors to monitor the ice column and ocean beneath the ice shelf in the critical area of the grounding line (the point where the glacier goes afloat to become ice shelf).

Geophysical Habitat of Subglacial Thwaites
Read more of: Geophysical Habitat of Subglacial ThwaitesGHOST is an ice-based project which will examine the bed beneath the Thwaites Glacier, to assess whether conditions are likely to allow rapid retreat, or if the retreat may slow or stop due to a ridge 70 km inland.

Ocean-driven ice-shelf thinning in Antarctica
Read more of: Ocean-driven ice-shelf thinning in AntarcticaBy exploiting advances in ice sheet modelling, and new Antarctic-wide datasets, this project aims to predict how far and how fast the observed ocean-driven thinning of floating ice shelves will propagate into the interior of the Antarctic ice sheet, and assess the consequences for global sea level over decadal-to-centennial timescales.

Ice Sheet Modelling
Read more of: Ice Sheet ModellingThe ice sheet modelling group integrates observational data with dynamical models to improve our representation of how the ice flows beneath the surface, and to reveal how the shape and flow of the Antarctic ice sheet has changed in the past.

Maps reveal landscape beneath Antarctica’s weak underbelly
Read more of: Maps reveal landscape beneath Antarctica’s weak underbellyA UK team of researchers has produced high-resolution maps of the bed beneath a major glacier in West Antarctica, which will help them predict future sea-level rise from this region. […]
