Abstract: |
This dataset includes all sediment analyses performed on core AST-P2-18 from lake Ástjörn on northern Iceland and include all data presented by van der Bilt et al. 2021 (Communications Earth & Environment: accepted, but at the time of uploading only available as a pre-print: 10.21203/rs.3.rs-83734/v1). Core AST-P1-18 (described in the manuscript) was not analyzed as it covered a shorter sequence. The investigated record has been extracted during the summer of 2018 with a piston coring device, analyzed throughout 2019 and covers the past 4.5 ka BP. Core AST-P2-18 was taken to investigate the timing and magnitude of glacio-volcanic megafloods from the Jökulsá á Fjöllum: lake Ástjörn sits above this river and therefore receives slackwater sedimentation when floodwaters spill into the basin. The data are organized per paper figure per .txt file: Fig. 5 includes EPMA (microprobe) data of analyzed glass shards used for tephrochronology, Fig. 6 includes all stratigraphic data generated on an ITRAX XRF core scanner/ProCon CT-ALPHA CT scanner/Mastersizer 3000 particle size analyzer as well as density and loss-on-ignition (LOI) measurements, while Fig. 7 includes grain size endmember modelling output. Additional details may be found in the appended readme file. |
