The cores show a sediment succession of the late Pleistocene and the Holocene. A core photograph is depicted, followed by a detailed core scetch and a depositional code for the depositional environment and facies. Samples taken for grain size, pollen, foraminifera, diatoms, macrobenthos, radiocarbon dating, XRD analysis and XRF data are marked in the columns right of the plot of the core. In the last column additional notes are given.The cores were taken in the backbarrier tidal flats of the Eastfrisian Island Norderney (central Wadden Sea, German North Sea coast) within the frame of the multidisciplinary national research project 'WASA – Wadden Sea Archive'. WASA has been undertaken to reconstruct submerged palaeo-landscapes in the central Wadden Sea. It was running from 2016 to 2020 (Bittmann et al. 2022).Each of the three cores were collected in the subital with a modified version of the vibrocorer VKG6 (medconsultant GmbH) which was used from aboard the research vessels FK SENCKENBERG (Senckenberg am Meer, SaM, Wilhelmshaven) and BURCHANA (Niedersächsischer Landesbetrieb für Wasserwirtschaft, Küsten- und Naturschutz, NLWKN, Norderney). The vibrocorer was deployed in full-weight load mode (1.1 t gravity weight) and was equipped with PVC liners of 5000 mm length maximum and 100 mm diameter. The cores were described based on the field proven core catalogue by Capperucci et al. (2022), which was developed on the base of all 140 cores taken in the area of Norderney within the WASA project. The core catalogue allows the identification of the local sedimentary sequences and their characteristic facies and depositional environments of the Late Pleistocene and Holocene of the central Wadden Sea.

Each of the files shows a core taken in the backbarrier tidal flats of the Eastfrisian Island Norderney (central Wadden Sea, German North Sea coast) in a jpeg file including a header with all metadata , e.g., coordinates, coring depth, operators, date of collection. A core photograph is depicted, followed by a detailed core scetch and a depositional code for the depositional environment and facies. Samples taken for grain size, pollen, foraminifera, diatoms, macrobenthos, radiocarbon dating, XRD analysis and XRF data are marked in the columns right of the plot of the core. Additional notes are given in the last column.
