CryoSat reveals surprising ebb and flow of subglacial lakes

Hidden from view by ice kilometres thick, there is a vast network of lakes and streams at the base of the Antarctic ice sheet. This subsurface meltwater affects the speed with which the ice sheet flows towards the ocean. Using a decade of altimetry data from ESA’s CryoSat satellite, scientists have made an unexpected discovery about how lakes beneath Thwaites glacier have drained and recharged in quick succession.
