| Zusammenfassung |
| Cold-water coral reefs are very abundant along the European continental margin in
intermediate water depths and are able to build up large mound structures. These carbonate
mounds particularly occur in distinct mound provinces on the Irish and British continental
margins. Previous investigations resulted in a better understanding of the cold-water coral
ecology and the development of conceptual models to explain carbonate mound build-up.
Two different hypotheses were evoked to explain the origin and development of carbonate
mounds, external versus internal control (e.g., Freiwald et al. 2004 versus e.g. Hovland 1990).
Several short sediment cores have been obtained from Propeller Mound, Northern Porcupine
Seabight, indicating that cold-water corals grew during interglacial and warm interstadial
periods of the Late Pleistocene controlled by environmental and climatic variability
supporting the external control hypothesis (e.g. Dorschel et al. 2005, R |
