Cluster analysis of open ocean samples from different geographical locations. (a) Geographical locations of the 56 global ocean samples. The 23 open ocean samples are indicated as follows: Sargasso Sea (n=7, blue), Caribbean Sea (n=2, cyan), Eastern Tropical Pacific (n=4, green), and Tropical South Pacific (n=10, red). (b) Clustering results of open ocean samples based on 5-tuples and dissimilarity measure d2S|M0.
