Tolerance to long-term exposure of suspended benthic sediments and drill cuttings in the cold-water coral Lophelia pertusa
The cold-water coral Lophelia pertusa was exposed to suspended particles (<63 mu m) for 12 weeks. Skeletal growth was significantly lower under exposure concentrations of similar to 25 mg l(-1) than similar to 5 mg l(-1) and there was a trend of lower growth rates when exposed to water-based dril...
