Mission Plan

Using several hundred samples previously collected from around the Arctic, this project aimed to establish a necessary baseline of microbiological community data by applying next-generation DNA sequencing technologies and cutting-edge bioinformatics approaches. Scientists referred to this strategy as ‘metagenomic mapping’ and have argued that more detailed metagenomic maps will lead to many future discoveries.
