(1) Propose a model of cold-water coral reef build-up(1) Propose a model of cold-water coral reef build-up=> CTscan images=> CTscan images – fossils identification – fossils identification
(3) (3) Document ocean circulation changes Document ocean circulation changes => Coupled U-series and Radiocarbon => Coupled U-series and Radiocarbon
dating on dating on Lophelia sp.Lophelia sp.
(2) Reconstruct the spatial and temporal growth (2) Reconstruct the spatial and temporal growth history of the reefhistory of the reef= > Downcore and surface dating= > Downcore and surface dating
(4) (4) Test if trace/minor elements composition in Test if trace/minor elements composition in Lophelia sp. Lophelia sp. skeleton could be used for palaeo-environmental skeleton could be used for palaeo-environmental reconstructions (i.e Temperature – Salinity) reconstructions (i.e Temperature – Salinity) => High resolution ion microprobe study=> High resolution ion microprobe study
