Relative abundance of marine microbes in the top 25 m of the ocean, partitioned between archaea, bacteria, cyanobacteria, chloroplast 16S rRNA, and eukaryotic 18S. (A) Relative abundance % (y axis) across longitude in decimal degrees (x axis) from MOSAiC within the Arctic Ocean. (B) Relative abundance % (x axis) vs latitude in decimal degrees (y axis) from within the Pacific Ocean, the Atlantic Ocean, and Indian Ocean (C) relative abundance (x axis) vs latitude in decimal degrees (y axis) from within the Southern Ocean.
