Polar glaciers may be home to previously undiscovered carbon cycle

Microbes in streams flowing on the surface of glaciers in the Arctic and Antarctic may represent a previously underestimated source of organic material and be part of an as yet undiscovered "dynamic local carbon cycle," according to a new paper published by researchers supported by the National Science Foundation (NSF).
The cycle, they argue, could become a significant global source of carbon as temperatures rise worldwide and microbial activity increases.
