We’ve wrapped up drilling at Crary Ice Rise with 228m of sediment core. This is an unprecedented record of the history of the West Antarctic Ice Sheet stretching back millions of years. Initial observations indicate the core includes periods of environmental change during past times of warming.

Our science team are preparing for when we have our first core on deck. They’ve dug out a pit for cold storage of microbiology samples. The warm science container has been transformed into a lab, ready to X-ray cores and take sediment samples for microbiological analysis.

It’s a very Crary Christmas for our on-ice team in Antarctica! After several weeks of weather delays preventing them getting out to our deep-field camp at Crary Ice Rise, on Christmas Eve the team received the best possible present – a Basler flight to Crary! Crary Christmas from SWAIS2C!

Chuffed to have contributed to this new QSR paper led by @geologicaljo.bsky.social! Check it out of you fancy learning about glacial deposits in the Hudson Mountains, West Antarctica, and what they tell us about past ice thicknesses, thermal regimes, and ice flow directions 🧊🇦🇶🏔️ tinyurl.com/yh9je8sf
Two maps - the first shows the Amundsen Sea Embayment, West Antarctica, and major glaciers that flow into it (most notably Pine Island and Thwaites glaciers). The second map shows the Hudson Mountains, a series of volcanoes adjacent to Pine Island Glacier and dissected by Larter and Lucchita glaciers.Three plots showing the surface profile (elevation) of Pine Island, Larter, and a Lucchitta glaciers against distance from ice shelf front or grounding line (km). Grey boxes above the surface profiles show the extent of exposed rock at each nunatak (a volcano in each case here). Different symbols in/on the grey boxes show the location and elevation of erratic cobbles collected or observed at each nunatak. There is a pie chart above each nunatak showing the different erratic lithologies observed.
