Short summary
Processes occurring at the earth's surface (erosion, dust formation, weathering) determine the evolution of the landscape and play an important role in the global climate. The present database (compiled from a literature search) helps to determine the neodymium and strontium radioisotope signature of terrestrial and marine sediments to determine their provenance as well as present and past sediment transport pathways to oceanic basins.
