(Table T1) Calcareous nannofossil abundance in ODP Hole 181-1123C sediments

Abundance estimates as follows: V = very abundant, A = abundant, C = common, F = few, R = rare, - = not found. Lowercase letters indicate reworked specimens. Sediment depth is given in mcd.

丰度分级标准如下：V = 极丰富（very abundant），A = 丰富（abundant），C = 常见（common），F = 稀少，R = 稀有，"-" = 未检出。小写字母代表再沉积标本。沉积物深度以 mcd 为单位。
