Raw data of two lake sediment cores from southern Norway to reconstruct the frequency of palaeo floods

The data is from two separate sediment cores (LYP118 and LYG118) retrieved in November 2018 from the same coring location in Lake Lygne, southern Norway. LYP118 was retrieved using a piston corer equipped with a 6 m PCV-tube, whereas LYG118 was retrieved using a a UWITEC gravity corer equipped with a 2 m plastic tube. The purpose was to reconstruct palaeo floods from the Lygna river system by identifying flood layers in the sediment record. The sediment cores were stored in a refrigerated room (4 degrees C) prior to analysis. The attached data includes continuous magnetic susceptibility (MS) data measured at 0.2 cm intervals and continuous x-ray fluorescence (XRF) data measured at 0.05 cm intervals. Additionally, there are three images from a CT-scan, highlighting layers of low (0-5th percentile) and high (90-100th percentile) density. The grainsize, dry bulk density (DBD), and loss-on-ignition (LOI) data are from 1 cm samples collected at specific depth intervals (see column I for depth interval).
