Coccolith morphotype counts, relative abundance, length measurements, and central tube: Length ratio (CT:L) for the most shallow sample at each site measured in this study.

All measurements and counts were obtained from SEM images. Mean length and mean CT:L are shown including the 95% confidence interval (CI 95%). N: Number of counted coccoliths. Rel. ab. (%): Relative abundance of morphotypes. Morphotype abbreviations: A: Type A, OA: Overcalcified Type A, B: Group B, M: Malformed coccoliths.

所有测量与计数工作均通过扫描电子显微镜（Scanning Electron Microscope, SEM）图像完成。文中给出了平均长度与平均CT:L比值，并附带95%置信区间（CI 95%）。其中，N代表所计数颗石的数量；Rel. ab. (%)指代各形态类型的相对丰度（Relative Abundance, Rel. ab.）。各形态类型的缩写说明如下：A为A型颗石，OA为钙化过度型A型颗石，B为B组颗石，M为畸形颗石。
