Thousands of tiny quakes shake Antarctic ice at night
Stay overnight on an Antarctic ice shelf, and you may feel the shaking from thousands of tiny quakes as the ice re-forms after melting during the day.

More than 26,000 years ago, sea level was much lower than it is today partly because the ice sheets that jut out from the continent of Antarctica were enormous and covered by grounded ice—ice that was fully attached to ...
