Researchers quantified the potential methane consumption rates of microbial communities living in carbonate rocks collected from seven geologically diverse deep-sea methane seeps, comparing the effects of microbial abundance, community composition, and mineralogical context on the consumption rates; the results showed that these understudied microbial communities may be ubiquitous in carbonate rocks at methane seeps throughout the ocean and have the potential to consume methane, a greenhouse gas, at rates up to 5,500 nanomoles per cubic centimeter per day.
