Summary Introduction

Introduction:

Lake Whillans is a small and shallow lake situated half a mile beneath polar ice sheets. I is completely encased in ice and sits along the slanting hill below the icy surface. The lake receives no sunlight at all, and a few millilitres of freshwater is added to it because the heat from the Earth’s core melts the ice. Scientists have drilled through this ice cover and collected water samples from Lake Whillans. They found approximately 4000 distinct microbial species in the samples.
