Productive and diverse microbial communities in aquifers (Alberta, Canada)
Groundwater ecosystems are globally widespread yet still poorly understood. We investigated the age, geochemistry, and microbiology of 159 groundwater samples from 95 monitoring wells (<250m depth) located in 14 aquifers in the Canadian Prairie. Geochemistry and microbial ecology were tightly linked revealing large-scale aerobic and anaerobic hydrogen, methane, nitrogen, and sulfur cycling carried out by productive and diverse microbial communities.
