Abstract
Bioerosion (Neumann, 1966) describes the disintegration processes of hard substrates such as calcareous skeletons through the activity of organisms by mechanical removal of carbonates (bioabrasion) or by chemical dissolution (biocorrosion) and is a well-known process in the alteration of shallow-water coral reefs. Endolithic organisms live within the skeleton either for protection or nourishment. The different bioerosional processes result in a destruction of reefal frameworks. The study of these ichnocoenoses (endolithic trace communities) allows to reconstruct (paleo-)environments and applicable depth zonations of neritic environmental settings through the Phanerozoic era.
The ichnodiversity in the course of time also forms integrals for the understanding of the longevity and fossilisation potential and will lead to the definition of ecologic "health conditions" of deep-water corals for a rapid large-scale assessment. In this presentation, the prevalent aphotic bioeroder community found within the skeleton of the cosmopolitan coral Lophelia pertusa from the Propeller Mound, Porcupine Seabight, sampled in 629 to 780 m water depth, is demonstrated using the vacuum-cast-embedding method with subsequent SEM analysis: Shown are coloured SEM pictures of resin casts with an accentuation of different boring organism groups.
