Grain size distribution of Wadden Sea sediment used in an experiment on sediment exposure of juvenile Caryophyllia (Caryophyllia) huinayensis


This table shows the grain size distribution of sediment used for a 12-week sediment exposure experiment, to test how juvenile Caryophyllia (Caryophyllia) huinayensis perform under increased sedimentation. Surface (1 cm) sediment samples were collected from the Wadden Sea in front of Spieker-Neufeld in October 2020 and February 2021. Prior to the use in the experiment, the sediment was sieved into fractions that were mixed proportionally to match the size range of the sediments in Comau Fjord (approx. 42°11' – 42°29'S and 72°35' – 72°22'E, a natural habitat of C. huinayensis). Organic carbon was then removed with H2O2 until the reaction stopped and the sediment was washed for neutralisation. Grain size measurements of the sediment used in the experiments were performed before, during and after the experiment in the Particle-Size Laboratory at MARUM, University of Bremen with a Beckman Coulter Laser Diffraction Particle Size Analyzer LS 13320 that provides grain size distributions in the size range from 0.04 to 2000 μm, divided into 116 size classes.

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.
