(Table 2) Nannoplankton occurrences in DSDP Hole 89-586B

Sediment depth is given in mbsf. Species abundance: A = abundant (>50 specimens), C = common (25-49 specimens), and R = rare (<25 specimens) - = absent, obtained by...沉积物深度以海底以下米数（meters below sea floor，mbsf）为单位。物种丰度分级规则如下：A代表丰富（标本数量＞50个），C代表常见（标本数量25~49个），R代表稀少（标本数量＜25个），"-"代表缺失，该数据集通过……获得。
