Antarctic lakes (above and beneath the ice sheet): Analogues for Mars
The perennial ice covered lakes of the Antarctic are considered to be excellent analogues to lakes that once existed on Mars. Field studies of ice covered lakes, paleolakes, and polar beaches were conducted in the Bunger Hills Oasis, Eastern Antarctica. These studies are extended to the Dry Valleys,...

The perennial ice covered lakes of the Antarctic are considered to be excellent analogues to lakes that once existed on Mars.
