Distribution of SAR324 metabolic pathways at Station ALOHA. Hierarchically clustered heatmap of depth (blue) distribution of metabolic pathways in metagenomes from HOT time-series. Heatmap of distribution over time has been overlaid in purple. Depth and time distribution of each pathway have been scaled from 0 to 1. Average coverage over depth is displayed in red for each pathway. Color backgrounds have been applied to pathway clusters according to the depth at which their relative abundance peaked, from yellow in the surface to dark blue in the deep
