Using sophisticated geochemical techniques to analyse the water trapped within sediment cores recovered from the sea-floor of Pine Island Bay, the team concludes that the area once featured several sub-glacial lakes, the largest of which was the size of Loch Lomond. The results were published this month in the journal Nature Communications.
