Short summary
Here we present the updated International Soil Radiocarbon Database version 2, which compiles radiocarbon data from over 500 studies at 1700 locations worldwide. The database provides various soil radiocarbon measurements to improve our understanding of factors that influence the age distributions of carbon in soils. While we have made progress expanding the database and improving its structure, important gaps remain in tropical regions, deep soils, and certain measurement types.
