The table shows the calyx diameters of the juvenile Caryophyllia (Caryophyllia) huinayensis measured in ImageJ (Version 1.53), separated according to exposed sediment concentration at the beginning of the 12-week sediment exposure experiment (week 0), in the middle (week 6) and at the end (week 12). Corals were exposed to three concentrations, a natural (0.0042 ml/l) and a 100-fold and a 1000-fold increased sediment concentration.

C. huinayensis calyx diameter increase (parameter 11) denotes the daily increase of the calyx diameter in percent. This is only shown for the final measurement, as it was calculated as the difference between the final and the initial values.This dataset was generated within the framework of the co-operation between the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (programme: 'Changing Earth – Sustaining our Future', Topic 4.2), the Huinay Scientific Field Station, European Union's Horizon 2020 iAtlantic project (Grant Agreement No. 818123) and the Centre for Marine Environmental Sciences of the University of Bremen.
