Average percentage abundance identified from each ICoMM project, normalised for sequencing effort. Data was compiled from publically accessible data at ICoMM Marine Microbes Database (http://vamps.mbl.edu/). CAM: census of Antarctic marine life [16]; AWP: Azores water profile; AOT: Atlantic Ocean transect; ABR: active but rare (Nth and Sth Pacific) [17]; LCR: latitudinal gradient from South Atlantic to the Caribbean [18]; PML, English Channel L4, UK [19]; CCB: microbial diversity in Caribbean coral species; CMM: coastal microbial mats; SPO: marine sponge-associated bacteria [20].
