Data & Code Accessibility

The GCRMN produces estimations regarding the status and trends of coral reefs using data acquired by the members of the GCRMN network. The data are collected following Data Sharing Agreements (DSA) with data contributors and as such the GCRMN is not the owner of datasets shared by its members. Therefore, for the “Status of Coral Reefs of the World: 2025” report, the GCRMN is unable to share the raw datasets. However, some members of the GCRMN network and report contributors have made their datasets publicly available. For benthic cover monitoring data, such open access datasets are listed here.

All code used to produce the results and figures presented in the “Status of Coral Reefs of the World: 2025” GCRMN report is openly available on a GitHub repository. This repository allows full reproducibility and transparency of the analyses.
