Resumen de Antarctic aquifers may teem with life
Antarctica's Blood Falls are well named. There, the white tongue of the Taylor glacier is stained crimson, as if the ice itself has been wounded. The iron in the water comes from the weathering of the bedrock beneath the ice, a process enhanced by microbial action. This unique feature is much more than a curiosity--it is a portal into the Antarctic subsurface, a hint at what lies beneath, says Jill Mikucki at the University of Tennessee in Knoxville.
