Abstract:
A representative split of 356 washed samples (>38µm) was analysed for foraminifera size. Size parameters of randomly oriented foraminifers were measured using a Malvern Mastersizer laser granulameter. The maximum diameter of the object was chosen as the most suitable size estimator because it is least affected by random orientation. The 90th percentile of the maximum diameter (or D90) was used to describe these strongly skewed distributions.
