This project aims to investigate the interconnected processes that led to past reef growth and demise. The iconic Great Barrier Reef and reefs globally are under threat. Yet reefs appear to have undergone cycles of death and recovery, though the causes are poorly understood. This project will reconstruct past climate, rainfall, water quality, coral bleaching and reef ecology feedbacks across Great Barrier Reef death events to establish which environmental stressors and paleoclimate variations are most critical for reef health. The outcomes will better constrain long term coral reef dynamics and provide significant benefits to those who manage reefs globally, since the Great Barrier Reef covers the full range of reef environments.

该项目旨在调查导致过去珊瑚礁生长和死亡的相互关联的过程。标志性的大堡礁和全球的珊瑚礁正受到威胁。然而，珊瑚礁似乎经历了死亡和恢复的循环，尽管其原因尚不清楚。该项目将重建大堡礁死亡事件中过去的气候，降雨，水质，珊瑚漂白和珊瑚礁生态反馈，以确定哪些环境压力和古气候变化对珊瑚礁健康最重要。这些成果将更好地限制珊瑚礁的长期动态，并为全球珊瑚礁管理者提供重大利益，因为大堡礁涵盖了所有珊瑚礁环境。
