(Table 3) Relative abundances in percentages of attached and free-living microbesa from water sample station GeoB15704-2

Only microbial groups observed within the aggregates were used to calculate the relative abundances by dividing the microbial abundance for each group by the total number of microbes in all groups. The relative abundances were used to compare the attached microbial community structure with the free-living bacteria at different depths using a
