TABLE 1.

Average abundances and relative contributions of major taxa to the observed BCC differences among samples from the GRNMS, revealed by SIMPER analysis^a

^aAvg, average relative abundance; δ_i, estimated individual contribution of a bacterial taxon to the observed between-sample differences; spr, spring; surf, surface water; md, mid-depth water; bot, bottom water. Shading highlights the top four contributors for each comparison group.

^bAverage relative abundances of the taxa in samples taken at different depths were measured in the spring.

^cAverage relative abundances of the taxa in samples taken during the day and at night were measured in the fall.
