深海钻探项目第15航次采集的岩芯中发现的钙质微型浮游生物的这一记录旨在帮助选择样本进行更详细的研究。钙质超微化石的丰度和保存状态的指示在本卷中描述岩心的部分中给出。本章包括：（1）已确认物种清单;（2）用于确定样品地层位置的最高和最低产出面和带的摘要，以及关于每个钻孔中每个地表位置的数据;（3）一系列表格，列出关于每个已检查样品中已确认物种丰度的数据;（4）在147、148、149和154 A孔发现的更新世钙质超微化石的特殊剖面。
This account of the calcareous nannoplankton encountered in cores recovered on Leg 15 of the Deep Sea Drilling Project is intended to serve as an aid in the selection of samples for more detailed studies. Indications of the abundance and state of preservation of calcareous nannofossils are given in the sections of this volume dealing with the description of the cores. This chapter contains (1) a list of the species recognized; (2) a summary of the highest and lowest occurrence surfaces and zones used to determine stratigraphic position of samples, with data on the position of each surface in each of the holes cored; (3) a series of tables presenting data on the abundances of the species recognized in each of the samples examined; and (4) a special section on the Pleistocene calcareous nannofossils found in Holes 147, 148,149, and 154A.
