Cracking Antarctica’s Iceberg Code

RIFT-TIP is investigating iceberg calving on the Brunt Ice Shelf. It uses field monitoring, lab testing, and modelling to predict when icebergs will form.

Reducing uncertainty in sea-level predictions

OCEAN:ICE studies how Antarctic ice and Southern Ocean processes drive sea-level rise and influence global climate, using new data and advanced ice–ocean–climate models.

Melting at Thwaites Grounding Zone and its Control on Sea Level

MELT 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

GHOST 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.

International Thwaites Glacier Collaboration

The International Thwaites Glacier Collaboration unites global scientists to study Antarctica’s most vulnerable glacier, predict sea-level rise, and inform climate action worldwide.

Ocean-driven ice-shelf thinning in Antarctica

By 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

The 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.

iStar-D will identify the potential contribution to sea-level rise, from ice locked in the Amundsen Sea sector of Antarctica

Maps reveal landscape beneath Antarctica’s weak underbelly

A 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. […]
