Šujan et al investigate the Early Pleistocene sediments in Lithuania, and conclude that the first advance of the Fennoscandian Ice Sheet there happened during the Elsterian Glaciation (MIS 12). A unit that was previously interpreted as an earlier advance is now interpreted as a debris flow.

I worked with a great team of collaborators to produce a uniquely long #paleoclimate record from #caves in northern #utah. We dated stalagmites to show that mountain #permafrost repeatedly expanded during glacial periods and disappeared during interglacials in sync with orbital climate cycles over the past ~600,000 years. These results provide rare long-term constraints on alpine permafrost sensitivity and help place modern permafost thaw into a deeper climatic context. The paper was published in Quaternary Research; if you do not have access and wish to get a copy, feel free to send me a private request.

Quaternary (Geological periods 🌍)

The Quaternary is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy, as well as the current and most recent of the twelve periods of the Phanerozoic eon. It follows the Neogene Period and spans from 2.58 million years ago to the present. The Quaternary ...

What did Beringia look like in the last “ice-age?” Alistair Monteath et al.¹ have just published an impressive review article!
I will need some time to read through it.
The more detailed fossil-based understanding of vegetation and soil is really important for a clearer picture of the plant–herbivore interactions. In the end, it’s so much more complex than the naïve concept of a homogenous mammoth steppe grassland…

🔦 Feldforschung in Alaska: Der #Geologe Paul Wilcox entdeckte dort in einer schwer zugänglichen Höhle rund 20.000 Jahre alte Ablagerungen. Eine Analyse dieser Proben erlaubte Rückschlüsse über das Ende der letzten #Eiszeit und darüber, wie das Abschmelzen der riesigen Gletscher damals vor sich ging.
