Sedimentation can bury corals, cause physical abrasion, and alter both spectral intensity and quality; however, few studies have quantified the effects of sedimentation on coral reef metabolism in the context of episodic sedimentation events. Here, we present the first study to measure coral community metabolism - calcification and photosynthesis - in a manipulative mesocosm experiment simulating a pulse sediment event. We exposed a mixed benthic community composed of 75% live carbonate rubble cover and 25% Montipora capitata coral cover to an approximately 275 mg cm−1 (sediment accumulation) acute pulse sediment loading event. No differences were found in net calcification or net photosynthesis between the control and treated mesocosms 48 h and 25 d following exposure to pulse sediment input. Results from this community experiment indicate the ability of Montipora capitata, a common reef coral, to persist under these acute sediment levels, demonstrating resistance to episodic sediment events.
