Metagenomic survey of the taxonomic and functional microbial communities of seawater and sea ice from the Canadian Arctic.
International audience Climate change has resulted in an accelerated decline of Arctic sea ice since 2001 resulting in primary production increases and prolongation of the ice-free season within the Northwest Passage. The taxonomic and functional microbial community composition of the seawater and s...
