This year's holiday card embellishes an image selected from our Polar Geomicrobiology Group, taken by Alex Michaud on Whillans Subglacial Lake in 2013. The Lake's namesake, Ian Whillans, was a renowned glaciologist at the Byrd Center who was instrumental in revealing the unstable nature of the West Antarctic Ice Sheet.
