Mayfield has carried out global climate change (GCC) simulation experiments on coral reef mesocosms and developed molecular biological tools for assessing reef coral health. Mayfield is now attempting to use the molecular biotechnological protocols and coral “stress test” assays he developed in Asia with corals from ACCRETE’s GCC manipulation experiments and the South Florida reef tract (particularly reefs that have been found previously by the ACCRETE team members to span a gradient of resilience from highly heat tolerant to extremely sensitive to environmental perturbations). Mayfield's ultimate goal is to create a means of predicting coral health on a pre-death timescale such that coral reef “triage” could be enacted in situ.
