Estimated size–weight scaling and its 95% confidence interval of Globigerina bulloides, Globigerinoides ruber (white), and Globigerinoides elongatus, sampled from March 2002 until April 2003 with sediment trap L1/K276.

Some samples either contained no or too few specimens to estimate the scaling or its confidence interval, or were not significant in the Kendall–Theil robust line fitting, and were thus not included in the analysis. A possible annual mean value of the size–weight scaling per species, that would never fall outside the 95% confidence interval, is indicated as well (in Globigerina bulloides this only works if one sample from early May 2002, marked by the green arrow, is regarded as an outlier). Gray boxes with letters at the bottom indicate months, the vertical, dashed, gray line marks the end of 2002.
