Effects of sediment load on polyp extension of the juvenile cold-water coral Caryophyllia (Caryophyllia) huinayensis ...

The table shows the polyp behaviour of juvenile Caryophyllia (Caryophyllia) huinayensis during a 12-week sediment exposure experiment. Corals were exposed to a natural (0.0042 ml/l), a 100-fold and a 1000-fold increased sediment concentration and observed three times a week, two hours after feeding...

Description
Summary:The table shows the polyp behaviour of juvenile Caryophyllia (Caryophyllia) huinayensis during a 12-week sediment exposure experiment. Corals were exposed to a natural (0.0042 ml/l), a 100-fold and a 1000-fold increased sediment concentration and observed three times a week, two hours after feeding start and once a week without feeding, by illuminating only the targeted coral briefly with a spotlight torch. Polyp extension was categorized into three groups: A = polyp fully extended (polyp fully visible, 100 %), B = polyp partly extended (polyp partly visible, 50 %) and C = polyp fully retracted (polyp tentacles not visible, 0 %). ... : 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. ...
