Table 1. 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.
