| Zusammenfassung |
| Interglacials have long been distinguished on basis of their marine isotopic signatures and,
on land, by their terrestrial fossil assemblages. High-resolution correlation between the
marine and terrestrial realms is of utmost relevance for studies of past climate changes and
how those might inform us on the future. However, slow accumulation rates and
bioturbation effects may result in an attenuated expression of climate change in the marine
record, while in the terrestrial record the global climate component may be convolved in a
more local or regional climate signal. For our understanding of (palaeo)climate to advance
and to delineate potential regionality in the expression of climate change, high-resolution
correlation between the marine and terrestrial realms is of utmost relevance. High resolution
terrestrial sequences, however, often represent comparatively short time
intervals, which hampers clear-cut correlation to deep sea and ice core records. Here we
report on climatic and chronological proxy records derived from an interdisciplinary study
of the infill of a small basin at Neumark Nord (NN) 2, Germany, which contains abundant
traces of Neandertal activity during the last interglacial. Palaeomagnetic analysis
revealed a high-resolution record of the Blake Event which we are able to position in the
early part of the Last Interglacial (Eemian) pollen sequence identified from the same
location. The NN2 data now enable precise terrestrial-marine correlation for the Eemian
stage in central Europe and demonstrates a surprising time lag between
the MIS 5e ‘peak’ in the marine record and the start of the Last Interglacial in this region. |
