The frozen mass covers Lake Vostok, a freshwater lake.. news.nationalgeographic.com Antarctic Lakes: 145 and Counting, Scientists Say John Roach for National Geographic News November 1, 2004 Don't don your swim trunks just yet, but deep beneath the Antarctic ice sheets are at least 145 lakes that may be teeming with microscopic organisms similar to those that could be thriving beneath the ice on Jupiter's moon Europa, according to scientists.
