Erosion intensity recorded in Lake Savine (North-western Alps) over the last 5600 years


Information on the production of the dataset: The sediment record of Lake Savine consists partly of flood deposits characterised by the succession of three facies: coarse-grained and well-sorted sediment facies, a less sorted sediment facies with finer particles and a clayey cap, from bottom to top. Based on the age-depth model constructed without considering these instantaneous events (see Sabatier et al. 2017), a flood frequency with a window of 101 years was calculated. This record is used as a proxy for erosion intensity. Another proxy for erosion is the continuous sedimentation rate (i.e. sedimentation between flood deposits). The sum of this sedimentation rate with the thickness of the flood deposits provides a "total accumulation rate" which reflects the total erosion dynamics in this catchment. The signals have been standardized by calculating z-scores.
