Abstract
Abstract. Four remarkable Pleistocene cliff outcrops scattered across the peninsula of Jasmund exhibit the dynamics of the Scandinavian Ice Sheet during the Weichselian glaciation in this area. The investigated sites display up to 30 m thick sequences of glacial tills with intercalated (glaci)fluvial to (glaci)lacustrine sediments. Based on detailed lithofacies analyses and a physical age chronology, we trace the reconstruction of the depositional sequences and their corresponding stratigraphic position within the Weichselian record.
Highlights
For the reconstruction of the Weichselian SIS oscillations and their response to climate signals, an accurate and absolute age constraint of the different ice extents is required
Optically stimulated luminescence (OSL), infrared stimulated luminescence (IRSL), and terrestrial cosmogenic nuclide (TCN) dating methods have opened up new avenues to refine the chronology of single ice advances of the SIS during MIS 3 and 2 (e.g. Rinterknecht et al, 2014; Hardt et al, 2016; Kenzler et al, 2017)
In Mecklenburg-Western Pomerania, only a few of the surface exposure dating (SED)-dated erratic boulders are related to Weichselian ice marginal positions (IMPs) (e.g. Rinterknecht et al, 2014), and most of the radiocarbon ages are Late Glacial to Holocene (e.g. Lampe et al, 2016)
Summary
This article gives an overview of the current state of research on the peninsula of Jasmund, with special consideration given to the stratigraphy of the Pleistocene deposits. The southern maximum extent of the SIS during the Weichselian glaciation reached from Denmark across northern Germany through Poland and the Ukraine in the southeast of Europe. After more than 130 years of Quaternary research, the timing and even the number of SIS advances into the southwestern Baltic Sea area during the last glaciation are still unclear and far away from being solved (Hughes et al, 2016).
