Comment:
Information on the dataset production: The sediment record of Lake Anterne is mostly made of flood deposits characterized by the succession of three facies: a coarse-grained and well-sorted sediment facies, a less sorted with finer particles sediment facies and a clayey cap, from the bottom to the top. The thickness of these deposits varies from millimeters to tens of centimeters. Only the deposits greater than 5 millimeters were identified and listed. Based on the age-depth model built without taking into account these instantaneous events (see the list of radiocarbon dates in https://doi.org/10.1594/PANGAEA.842827 and the associated manuscript Giguet-Covex, C et al. (2011): Changes in erosion patterns during the Holocene in a currently treeless subalpine catchment inferred from lake sediment geochemistry (Lake Anterne, 2063 m a.s.l., NW French Alps): The role of climate and human activities. The Holocene, 21(4), 651-665, https://doi.org/10.1177/0959683610391320), a flood frequency has been calculated with a 101-running window. This record is used as a proxy of erosion intensity. Another proxy for erosion is the continuous sedimentation rate, which also mostly includes flood deposits but with a thickness lower than 5 mm. The sum of this sedimentation rate with the thickness of flood deposits higher than 5 mm provides a "total accumulation rate" which reflects the total erosion dynamics in this catchment. The signals have been standardized by calculating z-scores.
