Abstract:
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).
