Notes: The relative abundance of benthic foraminiferal species is given as a percentage, where + = <1%. Absolute abundance (per ~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).
