Figure F18. Micropaleontological age datums and rank abundances of taxa indicative of paleoclimatic conditions, shown as a composite from Holes U1417A–U1417E. Relative abundance of foraminifers is shown. NPD = Neogene North Pacific Diatom zone of Yanagisawa and Akiba (1998), CM = California margin. Abundance: A = abundant, C = common, F = few, R = rare, P = present, X = present.
