The Danakil Depression in Ethiopia is one of the most inhospitable places on Earth.

The introduction and concentration of electron donors and acceptors in the subsurface biosphere is controlled by the mixing of subsurface fluids, but the mechanisms and rates at which microbial communities respond to changes induced by fluid mixing and transport are relatively unknown.
