Chronology from sediment core HZM19, Holzmaar (West-Eifel Volcanic Field, Germany)

Chronology is based on Birlo et al. 2023, the Age is in calibrated years Before Present. The sediment core HZM19 was collected in 2019, from Holzmaar, West-Eifel Volcanic Field in Germany using a UWITEC Piston Corer. The sediment core was collected to reconstruct environmental and climate changes of Holzmaar for the last 16,000 years cal BP. Particularly in this data set we cover between 2450-2950 cal BP.

X-ray fluorescense (XRF) core scanning from sediment core HZM19, Holzmaar (West-Eifel Volcanic Field, Germany)

XRF measurements in 0.2 to 1 mm increments with an ITRAX XRF core scanner (Cox Analytics) and Cr tube (Croudance et al. 2015, doi:10.1007/978-94-017-9849-5 ). The sediment core HZM19 was collected in 2019, from Holzmaar, West-Eifel Volcanic Field in Germany using a UWITEC Piston Corer. The sediment core was collected to reconstruct environmental and climate changes of Holzmaar for the last 16,000 years cal BP. Particularly in this data set we cover between 2450-2950 cal BP.

CNS analyses from sediment core HZM19, Holzmaar (West-Eifel Volcanic Field, Germany)

C, N and S analysed with a CNS elemental analyser (EuroEA, Eurovector). Biogenic silica was measured following the leaching method of Müller & Schneider (1993, doi:10.1016/0967-0637(93)90140-X). The sediment core HZM19 was collected in 2019, from Holzmaar, West-Eifel Volcanic Field in Germany using a UWITEC Piston Corer. The sediment core was collected to reconstruct environmental and climate changes of Holzmaar for the last 16,000 years cal BP. Particularly in this data set we cover between 2450-2950 cal BP.

Diatom counts from sediment core HZM19, Holzmaar (West-Eifel Volcanic Field, Germany)

Diatom analyses were done following (Battarbee, 1986; Battarbee et al., 2002; doi:10.2478/s11756-019-00407-8). Including an updated list of names. The sediment core HZM19 was collected in 2019, from Holzmaar, West-Eifel Volcanic Field in Germany using a UWITEC Piston Corer. The sediment core was collected to reconstruct environmental and climate changes of Holzmaar for the last 16,000 years cal BP. Particularly in this data set we cover between 2450-2950 cal BP. An aliquot of each freeze-dried sample was processed with standard procedures (Battarbee, 1986; Battarbee et al., 2002). Only species with >=5% relative abundance in at least two samples were used for further analyses. Species acronyms are listed seperately.
