Glaciology: Ice-sheet plumbing in Antarctica
Garry K. C. Clarke1
Abstract
It's not easy to work out what is going on beneath four kilometres of ice. But remote imaging has enabled the discovery of the long-distance discharge of water from one subglacial lake to another in Antarctica.
It is old news that there are lakes under the Antarctic ice sheet1 — indeed, Earth's seventh largest lake, Lake Vostok2, lies deep beneath the Antarctic ice. But are the lakes that form beneath great ice sheets long-lived and stable, collecting and spilling water at a steady rate?
