This dataset contains date, mean salinity, temperature, pH and oxygen values of the artificial sea water within 340 ml glass beakers (n=10), which were used as incubation vessels for juvenile Caryophyllia (Caryophyllia) huinayensis, specified according to the exposed sediment concentration: a natural (0.0042 ml/l), a 100-fold and a 1000-fold sediment concentration.

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.
