2D non-metric multidimensional scaling (NMDS) plots of metabolite similarity according to sample depth across multiple likelihood thresholds. Triplicate samples are represented by the vertices of the triangles and colored by the depth from which they were sampled (DCM = deep chlorophyll maximum, ~ 110 m). “Only good MFs” refers to those features manually labeled as “Good”. NMDS stress values are reported in the upper right corner of each plot
