Principal coordinates analysis of the census counts of planktonic foraminifera carried out among (A) all surface samples, (B) all downcore samples with each site treated as a group and (C) all samples grouped by their hydrographic signature. The p value of the associated ANOVA is shown for (B) and (C) only because there is only a single surface sample per locality in (A). The graphs were generated with R55 using the ggplot2 package59.
