Fig. 3

A The taxonomic composition of sediment, rock, and seawater communities. B Chao1 estimated microbial richness, showing a significantly higher richness in the rock and sediments samples, compared to the seawater communities (two-sided T-test: P = e−8). C Heatmap showing the relative abundance of OTUs (columns) per sample (rows) and their distribution across sample types. The community detected on the ultramafic rocks was significantly different compared to the seawater communities (ANOSIM: P = 0.001). More than half of the total OTUs detected were found only in the seafloor samples (rocks and sediments).
