Short summary

Concurrent sampling of environmental parameters, productivity rates, photopigments, and DNA was used to analyze 24 L estuarine diatom bloom microcosms. Biogeochemical data and an ecological model indicated that the bloom was terminated by grazing. Comparisons to previous studies revealed (1) additional community and diversity complexity using 18S amplicon vs. traditional pigment–based analyses and (2) a potential global productivity–diversity relationship using 18S and carbon transport rates.
