Notes: The relative abundance of benthic foraminiferal species is given as a percentage, where + = <1% and P = present (the relative abundance was not calculated because of small sample size). Absolute abundance (per11 ~20 cm3 of sediment) of benthic foraminifers is given as A = abundant (<500 specimens); C = common (250–500 specimens); F = few (100–249 specimens); R = rare (50–99 specimens); T = trace (1–49 specimens); and B = barren (no specimens).
