Polynesia Mana: Coral Reef Monitoring in French Polynesia
Project Overview:
Since 1991, this project has conducted long-term coral reef monitoring across French Polynesia and neighboring regions, including Pitcairn, Kiribati, Samoa, Tonga, and the Cook Islands. Surveys are carried out at each site every two years to track changes in reef health and biodiversity.
Program Partners
- CRIOBE
Location
- Tikehau, Raiatea, Takapoto, Samoa, and Tonga
Expected Time Frame
- March - November 2026
Duration of Expedition
- 2-7 Days
Accommodation Needed
- 2-3 Researchers
Special Equipment Needed
- Swim platform (hydraulic or stationary) or easy access to water; access to tender or smaller vessel; compressor (for scuba diving).
Expedition parameters listed above are flexible and negotiable.
Background:
These monitoring efforts are supported by the French National Center for Scientific Research (CNRS) and enhanced through cutting-edge technology developed in collaboration with institutes such as the University of California, San Diego’s Sandin Lab. This includes advanced techniques like photogrammetry and environmental DNA (eDNA) analysis.
Mission:
The primary goal is to collect consistent, long-term data on coral reefs in the region, including measurements of coral cover, fish densities and biomass, water temperature, wave activity, and other key indicators. This data helps identify and analyze global trends affecting coral reefs in the area.
Applications:
These research reports are shared with local authorities who may use the data to inform conservation policies and decisions.
