Note: Abundance: D = dominant, A = abundant, C = common, F = few, R = rare. Preservation: VG = very good, G = good, M = moderate, P = poor. See “Foraminifers” in the “Site U1312–U1315 methods” chapter. PF = planktonic foraminifers. d = dextral, s = sinistral. P in ostracodes column = presence of valves. IRD = ice-rafted debris, FaO = first abundant occurrence, LO = last occurrence.
