Wrench normalized data lead to better downstream inferences. a The sum of log-fold changes of differentially abundant OTUs is used as a measure of net change experienced by a community. This value is plotted for the differentially abundant OTUs in the mesopelagic ocean layer relative to the surface layer in the Tara oceans 16S data, for Total Sum and Wrench normalization. b The same metric plotted for various major phyla of interest in the Tara oceans project
