(Table 3) Distribution of calcareous nannofossils in DSDP Hole 96-617@en

Sediment depth is given in mbsf. Abundances: V = very abundant (10-100 specimens/field), A = abundant (1-10 specemens/field), C = common (1 specimen/2-10 fields), F = few (1 specimen/11-100 fields), R = rare (1 specimen/101-1000 fields), magnification of x1250. Nannofossil zone = Emiliania huxleyi.沉积物深度以mbsf（海底以下米）为单位。丰度分级如下：V代表极丰富（10~100个标本/视野），A代表丰富（1~10个标本/视野），C代表常见（1个标本对应2~10个视野），F代表稀少（1个标本对应11~100个视野），R代表罕见（1个标本对应101~1000个视野）；观测放大倍数为1250倍。钙质超微化石带（Nannofossil zone）为赫氏艾密里藻（Emiliania huxleyi）。
