Figure S5. Unassembled paired-end reads (5.1 Gb) from the metatranscriptome were mapped to the Oceanospirillales draft genome. A total of 3.0 Gb from themetatranscriptome mapped to the assembled draft genome. The average contig coverage is shown above. Contigs containing COGs coding for methyl-accepting chemotaxis proteins are shown in red. Contigs containing COGs for flagellar processess are shown in green. COGs for pilin are shown in purple.COGs implicated in biofilm formation are shown in dark blue. COGs for nutrient acquisition are shown in light blue. COGs for signal transduction are shown in orange. COGs for plasmid maintenance and stabilization are shown in light brown. Contigs are shown in length order.

Figure S6. SR-FTIR analysis of proximal plume water. The spot labelled as 1 in the visible and infrared image corresponds to spectrum #1, which is interpretedas MC252 oil. Spot 2 corresponds with spectrum #2, which is interpreted as a a cluster of prokaryotic cells. Spot 3 corresponds with spectrum #3, which represents a mixture of prokaryotic cells and MC252 oil. Spot 4 corresponds to spectrum #4, which represents a blank spot.
