Growth of north-east Atlantic cold-water coral reefs and mounds during the Holocene: A high resolution U-series and C-14 chronology
We investigated the Holocene growth history of the Mingulay Reef Complex, a seascape of inshore cold-water coral reefs off western Scotland, using U-series and radiocarbon dating methods. Both chronologies revealed episodic occurrences of the reef framework-forming scleractinian coral Lophelia pertu...
