AB  - This study aimed at providing confidence in the predictability of the impacts of 
      drill cuttings (DC) discharge on the cold-water coral Lophelia pertusa. L. 
      pertusa was exposed to DC from offshore exploration in the lab with the goal to 
      assess precautionary thresholds of effects. Two exposure scenarios with DC were 
      tested: a long-term (LT) pulsed exposure (12 weeks, peak concentrations: 
      2-50 mg/L, mean concentrations: 1-25 mg/L) and a short-term (ST) continuous 
      exposure (2.5 weeks, mean concentrations: 4-42 mg/L). After exposure, a recovery 
      period of 16 and 4 weeks was maintained in LT and ST, respectively. While there 
      was an assumption that DC might result in an increase in respiration, decrease in 
      growth, enhanced mucus production, reduced fatty acid content, only a significant 
      rise was noted in skeleton growth at DC 4 mg/L and a significant increase of 
      mucus particulate organic carbon at 25 mg/L at end of the exposure. DC did not 
      markedly reduce prey capture rate consecutive to DC exposure. However, the effect 
      of DC produced an increase of coral polyp activity during exposure and a return 
      to pre-exposure conditions after cessation of DC, and coenosarc was smothered 
      from DC even after a long recovery period (4 weeks). Overall, a DC concentration 
      of 10 mg/L seems to represent a threshold above which changes in coral conditions 
      were observed however with no apparent physiological consequences for the coral 
      within the experimental time scale.
