Stratigraphic evidence for modern‐like glacier extents in south‐central Alaska within the last glacial period (MIS 3)

Boreas, EarlyView.
The last (Wisconsinan) glacial period was punctuated in North America by two glacial maxima, known as the Early and Late Wisconsinan glaciations. In Alaska, these maxima and their subsequent retreats have been the object of dating efforts to reconstruct local climatic events and compare them to global trends.

Middle to Late Pleistocene landscape evolution and glacial dynamics in the Eastern Alps: the Gröbminger Mitterberg record, Austria

Boreas, EarlyView.
Glacial erosion during the Last Glacial Maximum (LGM) has removed much evidence of earlier glaciations and interglacials in the European Alps. At Gröbminger Mitterberg (GM), beneath a blanket of LGM till, a distinctive sediment archive preserves deposits predating the LGM.

Palaeolandscape reconstruction of a shallow coastal embayment in Kattegat, Denmark—influence of sea‐level changes during the latest Pleistocene and Holocene

Boreas, EarlyView.
We analyse the geological processes of a coastal embayment in the Kattegat. Using high‐resolution seismic data and sediment cores, we describe a geological evolution from glacial to shallow marine stages with a variety of preserved facies from different depositional settings, including glacio‐lacustrine, telmatic, limnic and coastal environments.

Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

Boreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.
