| Zusammenfassung |
| Paleoclimate archives provide unique insights into the dynamics of the climate
system. However, time-scale uncertainties often inhibit the reliable investigation of
leads and lags as well as time-transgressive climate variations. Identification and
synchronization of common cosmogenic radionuclide variations in natural archives
can lead to improved chronologies. This approach has been successfully applied
to synchronize 10Be records from Greenland ice cores and 14C time-series from
trees.
Here, we explore the potential of this approach for the synchronization of the 10Be
records from varved sediments of Lakes Czechowskie and Tiefer See to 14C variations
inferred from the IntCal13 calibration record around the grand solar minima at 250 BP
(Maunder Minimum), 2800 BP (Homeric Minimum) and 5500 BP. We discuss the robustness
of the synchronization. Furthermore, we investigate lake/catchment characteristics that favor
the application of this method for comparing and synchronizing cosmogenic radionuclide
records from varved lake sediments to those from other environmental archives. |
