Short summary
In this study we present results from the first long-term bioerosion experiment (1–14 years of exposure) outside the tropical realm. A novel micro-CT approach was used to visualise and to quantify the development of macrobioerosion traces. After 14 years, 30 % of the original substrate volume was excavated chiefly by sponges. High spatio-temporal variability prohibited clear conclusions about the onset of macrobioerosion equilibrium conditions, calling for further long-term experiments.
