This data collection of age determination data from high latitude lake systems (50° N to 90° N, 55 sediment cores, and a total of 602 dating points) was part of the multi-core study of the LANDO approach. The term “LANDO” refers to the implementation by Pfalz et al. (2022), which stands for “Linked age and depth modeling”. We collected the data between 2018 and 2021 from either the Pangaea database, PaleoLake database, or tables within the main body or supplementary material of publications. The uploaded data collection contains links to the main data source and paper reference for the corresponding age determination dataset. The data harmonization followed the syntax and semantics proposed by Pfalz et al. (2021) on harmonizing heterogeneous multi-proxy data. This data collection is based on drilling campaigns from 1993 to 2020.

This dataset presents global revised age models for taxonomically harmonized fossil pollen records. The age-depth models were established from mostly Intcal20-calibrated radiocarbon datings with a predefined parameter setting. 1032 sites are located in North America, 1075 sites in Europe, 488 sites in Asia. In the Southern Hemisphere, there are 150 sites in South America, 54 in Africa, and 32 in the Indopacific region. Datings, mostly C14, were retrieved from the Neotoma Paleoecology Database (https://www.neotomadb.org/), with additional data from Cao et al. (2020; https://doi.org/10.5194/essd-12-119-2020), Cao et al. (2013, https://doi.org/10.1016/j.revpalbo.2013.02.003) and our own collection. The related age records were revised by applying a similar approach, i.e., using the Bayesian age-depth modeling routine in R-BACON software.
We complement the data publication by providing the source information on the references (most data are related to Neotoma) as a table linked to each Dataset ID. The data set and site IDs are from Neotoma if the data sets are derived from the Neotoma repository. In case of our own data collection efforts (Cao et al. (2020), Cao et al. (2013) and our own data), we used the already published PANGAEA event names in case they are related to the data or created our own site names with referencing to geographical regions similar to the Neotoma data naming principle.
