Subglacial Microbial Communities (Image 1)

A cross-section of Blood Falls, in Antarctica, shows how microbial communities survive. After sampling and analyzing the outflow from below the Taylor Glacier, an outlet glacier of the East Antarctic Ice Sheet in the otherwise ice-free McMurdo Dry Valleys of Antarctica, researchers believe that, lacking enough light to make food through photosynthesis, the microbes that live there have adapted over the past 1.5 million years to manipulate sulfur and iron compounds to survive.
