Data for: Higher flood-frequency periods linked to human activities, increased erosion, and rejuvenation of soils in a subalpine catchment

This data set concerns the analysis performed on Lake Gers sediment sequence and includes its age-depth model, data from the short-lived radionuclides, data of the grain-size of the sediments, loss-on-ignition, magnetic susceptibility, XRF geochemistry, the list of the instantaneous deposits, the erosion, the flood-frequency and the data of the DNA of mammals on trees.
