This database is the first formal version of PAGES' C-PEAT Global Peatland Carbon Database (GD), which contains 267 independently cataloged peat cores and a large number of observations from those cores, including: peat depths, organic matter content values, dry bulk density values, organic density values, as well as carbon and nitrogen content values (Loisel et al. Submitted). This Editorial publication, along with the published scripts for data and metadata retrieval (Ransby et al. 2025), are designed to streamline data use and citation.
