Glaciers with a layer of rocky debris on their surfaces are distinct from clean-ice glaciers, with debris mostly insulating the glacier ice. However, debris data are scarce. We present the Debris Database (DebDaB), a database of debris thickness and physical properties of debris, with data from 84 glaciers in 13 global glacier regions compiled from 172 sources and including previously unpublished data. DebDaB serves as an open central repository for the scientific community to do research on debris-covered glaciers.
