The core location was monitored in an earlier study. Based on monitoring, textural and chemical relationships, it has been hypothesized that the stable carbon isotope signal of the flowstone deposit is a regional humidity record, indicating wet periods 3.8 to 3.4, 3.0 to 2.8 and 2.0 to 1.6 ka cal BP, and a prominent dry period between 2.1 and 2.7 ka cal BP. Furthermore, stable H isotope data of inclusion-hosted water were used to reconstruct the atmospheric temperatures that fit independent regional paleotemperature records, indicating warm conditions around 2.7 ka BP and a relatively cold period between 2.5 and 1.5 ka BP. Comparisons with regional speleothem records and reconstructed North Atlantic Oscillation data indicate that the Late Holocene paleohumidity changes recorded by the BNT-2 stable carbon isotope record can be detected in the entire Western-Central European region with further links to the North Atlantic realm. © 2019 Elsevier Ltd and INQUA |
