A different sort of countdown was under way on New Year's Eve at a remote field camp in West Antarctica.

In this case, the count literally went down to near the bottom of the West Antarctic Ice Sheet (WAIS), where drillers extracted about 72 more meters of ice cores in five days, reaching a final depth of 3,405 meters for the multiyear WAIS Divide Ice Core project.
