Notes: Includes diatom upwelling and freshwater assemblages, opaline phytoliths, and silicoflagellates (in percentages). Abundance: A = abundant; F = few; C = common; T = trace; and R = rare. Preservation: G = good; M = moderate; and P = poor. PhFD = the ratio of opal phytoliths to freshwater diatoms, calculated as [phytoliths/(freshwater + phytoliths)] x 100 (Jansen et al., 1989).
