Heat map displaying the abundances of bacterial families identified on plastics particles collected from the North Atlantic Subtropical Gyre (NASG, samples PP1 to PE3; abbreviations: PP, polypropylene; PE, polyethylene) (29) and the NPSG (samples 2a to 15b). Heat map displaying the abundances of bacterial families identified on plastics particles collected from the North Atlantic Subtropical Gyre (NASG, samples PP1 to PE3; abbreviations: PP, polypropylene; PE, polyethylene) (29) and the NPSG (samples 2a to 15b). The abundance of each bacterial family in a sample is relative to the total number of SSU rRNA gene reads in that sample assigned a prokaryotic family. Families with abundances of >1% in at least one sample are shown. The average percent identities of sample reads to their top hit (NASG/NPSG) are in parentheses. Cyano, Cyanobacteria. Jessica A.
