Biogeographic partitioning of Southern Ocean microorganisms revealed by metagenomics
Summary We performed a metagenomic survey (6.6 Gbp of 454 sequence data) of S outhern O cean ( SO ) microorganisms during the austral summer of 2007–2008, examining the genomic signatures of communities across a latitudinal transect from Hobart (44° S ) to the M ertz G lacier, A ntarctica (67° S )....
