Notes: Based on microscopic analysis of biogenic sediment constituents >63 µm, particularly benthic foraminifers, from core catcher samples. Foraminifer assemblages: PF = planktonic foraminifers, ONBF = outer neritic to upper bathyal benthic foraminifers, ESBF = middle to inner neritic smaller benthic foraminifers, LBF = larger benthic foraminifers, Pres = preservation. Div = common and diverse, Dom = dominant; A = abundant, C = common, G = good, M = moderate, P = poor, R = rare, T = transported, VP = very poor, ? = uncertain. MBF = mixed benthic foraminiferal assemblages including inner/middle neritic with outer neritic/upper bathyal representatives.
