(Table 3) Distribution of calcareous nannofossils at DSDP Site 82-563 in the North Atlantic

Derived from a count of 500 specimens; Discoaster druggii and Discoaster kugleri are indicated as number of specimens relative to about 3000 coccoliths. The presence of species out of a count of 500 coccoliths is indicated with <0.1

本数据集基于500份标本的计数结果构建；德鲁吉盘星藻（Discoaster druggii）与库格勒盘星藻（Discoaster kugleri）的标本数量以约3000颗颗石（coccolith）为参照基准进行标注。在以500颗颗石为总计数的样本中，若某物种的丰度小于0.1，则以<0.1标识其存在情况。
