Short summary
Short summary
Over the past few decades, a lot of field-based work has been performed around the world to describe the carbon-sink capacity of peatland ecosystems. Here we provide a synthesis product that includes stratigraphic and chronological data from 267 peatland cores. Each one of these datasets is individually downloadable and openly usable through PANGAEA. We also provide scripts (R and Python) to download portions of the database.

Short summary
The peatlands of Central America are vastly understudied, despite their role as long-term carbon stores. This study presents 9 new peat-core datasets from different landscapes found across Costa Rica. Our approach includes multiple paleoenvironmental tools that provide peatland ages, peat-soil geochemical characteristics, and ecological succession histories. The total peat carbon store in Costa Rica is estimated at 0.15 gigatonnes and the averaged peatland carbon stock is 1080 Mg C/ha.
