The objective was to determine the surface-water response to environmental perturbations during the OAE. A decrease in surface water fertility at the two localities is suggested by an increase in relative abundances of taxa with oligotrophic affinities and a concomitant decrease in taxa with mesotrophic or eutrophic affinities. Oligotrophy and anoxia at both localities are likely responses to increased water-column stratification associated with the incursion of warmer waters from lower latitudes.
