Abstract:
Here we provide the age-depth models of sediment cores for Lake Kyutyunda (core PG2023) and Lake Lama (core PG1341) from arctic Siberia. Both models provide the temporal information for a project on sedimentary ancient DNA metabarcoding using the ITS marker for fungal composition and diversity changes as well the plant-specific g and h primers of the trnL gene to track changes of terrestrial plants (see von Hippel et al., 2022, Dryad Digital Repository).
The age-depth model of Lake Kyutyunda is an updated version of the age-depth correlation from Biskaborn et al. (2016) with refined correlation between the core segments, based on the IntCal20 calibration curve compiled in the R package 'Bacon'. This age-depth model covers the last 39.000 years.
The age-depth model of Lake Lama (Taymyr peninsula) is based on the Accelerator Mass Spectrometry radiocarbon dating of 19 core samples and two additional dated woody remains from Andreev et al. (2004). This age-depth model was established using the R package 'Bacon', based on the IntCal13 calibration curve and dates back 23.000 years.
