Replication Data for: Hydroclimate intensification likely aided glacier survival on Svalbard in the Early Holocene

This dataset includes the results of analyses presented in the study \"Hydroclimate intensification likely aided glacier survival on Svalbard in the Early Holocene\" by Auer et al. 2025. The study presents evidence of glacier survival on Svalbard during the warmer-than-present Holocene Thermal Maximum (HTM). The analyses were performed on sedimentary records from two lakes (Berglivatnet, Lakssjøen) which receive meltwater from the Åsgardfonna ice cap.The cores were extracted in the summer of 2021 using a Nesje corer (piston cores) and a UWITEC gravity coring system. Chronological data shows they cover ~14 ka. The data are organized per paper figure per .txt file and include magnetic susceptibility, chronology, X-ray Fluorescence, Computed Tommography and grain size analysis. Additional details may be found in the appended readme file.
