Key Points:

A team of 29 scientists and engineers from the SWAIS2C project successfully drilled a 228-meter sediment core from beneath 523 meters of ice at Crary Ice Rise in West Antarctica, marking the deepest sediment core ever recovered from under an Antarctic ice sheet.
The sediment core reveals alternating layers of glacial debris and marine mud containing light-dependent organisms, indicating periods when the site was open ocean rather than ice-covered, spanning roughly 23 million years including times warmer than today.
This discovery provides crucial new data directly from beneath the ice sheet, improving understanding of how the West Antarctic Ice Sheet has responded to sustained warming above 2°C, a key factor for predicting future sea level rise.
Crary Ice Rise’s unique location, where ice rests on bedrock rather than floating on ocean water, makes it a sensitive indicator of ice sheet stability and past retreat events, helping scientists identify environmental drivers behind ice margin fluctuations.
The sediment core will be distributed to over 120 scientists worldwide for detailed analysis, with findings expected to enhance climate models and improve forecasts of Antarctic ice melt and its impact on the 680 million people living in low-lying coastal regions.
