Caption

This is a schematic of the drilling rig used to collect the sediment core analyzed by Shakun and colleagues from beneath the Ross Ice Shelf. The drill penetrated 280 feet of ice, 2800 feet of ocean water, and 4200 feet of sediment, recovering a geological history of the Antarctic Ice Sheet stretching back millions of years.
