Carbonate budget of a cold-water coral carbonate mound: Propeller Mound, Porcupine Seabight
High resolution studies from the Propeller Mound, a cold-water coral carbonate mound in the NE Atlantic, show that this mound consists of >50% carbonate justifying the name ‘carbonate mound’. Through the last ~300,000 years approximately one third of the carbonate has been contributed by cold-wat...
