National Coral Reef Monitoring Program:
Monitoring Climate-Driven Impacts

bioerosion monitoring unit (BMU) A bioerosion monitoring unit (BMU) deployed in the Papahānaumokuākea Marine National Monument of the NW Hawaiian Islands.

A changing climate is impacting the nation’s coral reef ecosystems. Increases in ocean temperature and changes to ocean chemistry are causing widespread coral bleaching, more frequent disease, and reduced coral growth rates. Key indicators used to identify and monitor climate-driven trends are listed below.

  • Thermal stress – changes in sea temperature
  • Ocean acidification – changes in carbonate chemistry
  • Ecological impacts – data on coral growth rates, erosion, and community structure to understand impacts of thermal stress and ocean acidification on the ecosystem

Data collection methods include moored oceanographic and ecological instruments stationed at fixed points in the Atlantic and Pacific Oceans, water samples collected by divers, and satellite-based observations.

These extensive monitoring data provide a comprehensive view of climate change impacts on coral reef ecosystems and help identify areas of resilience and vulnerability. The data are also used in modeling efforts.
