Reef Metabolism Monitoring Methods and Potential Applications for Coral Restoration

Coral reef metabolism measurements have been used by scientists for decades to track reef responses to the globe’s changing carbon budget and project shifts in reef function.

Description
Summary:Coral reef metabolism measurements have been used by scientists for decades to track reef responses to the globe’s changing carbon budget and project shifts in reef function. Here, we propose that metabolism measurement tools and methods could also be used to monitor reef ecosystem change in response to coral restoration. This review paper provides a general introduction to net ecosystem metabolism and carbon chemistry for coral reef ecosystems, followed by a review of five metabolism monitoring methods with potential for application to coral reef restoration monitoring. Selected methodologies included those with measurement scales appropriate to assess outplant arrays and whole reef ecosystem outcomes associated with restoration interventions. Subsequently we discuss how water column and CO 2 chemistry could be used to address coral restoration monitoring research gaps and scale up from biological, colony-level metrics to ecosystem-scale function and performance assessments. Such function-based measurements could potentially be used to inform several goal-based monitoring objectives highlighted in the Coral Reef Restoration Monitoring Guide . Lastly, this review discusses important methodological factors, such as scale, reef type, and flow environment, that should be considered when determining which metabolism monitoring technique would be most appropriate for a reef restoration project.
