Late Holocene moisture variability in Arctic Alaska from chitin δ18O

Boreas, EarlyView.
Amplified warming in the Arctic has resulted in reduced sea‐ice extent, which can impact regional climate dynamics. Elucidating past moisture variability in response to changing temperatures and sea‐ice conditions can offer insight into how anthropogenic climate change may impact Arctic areas such as the Alaskan North Slope in the future. We contribute

Droughts and human impact in the ancient Uaymil region of the Maya lowlands inferred from a 2800‐year sedimentary archive at Lake Kaná, Mexico

Boreas, EarlyView.
The relationship between the climate and societal transformation in Maya lowlands has long been debated, particularly the role of drought in shaping the civilization trajectory during the Classic Period. A high‐resolution, multi‐proxy, geochemical record from Lake Kaná, located in the underexplored Uaymil region of the Yucatán Peninsula in Mexico ...

Drilling the Marathousa palaeo‐lake in Greece (Peloponnese): inferring the environmental context of a Middle Pleistocene archaeological site

Boreas, EarlyView.
The Megalopolis Basin is located in the central Peloponnese (Greece), a region that is situated along one of the primary Pleistocene biogeographical corridors for intracontinental hominin migration. The basin comprises several hundred metres of Plio‐Pleistocene sediments alternating between clastics and lignites.

Towards an ‘absolute’ timing of biostratigraphic and environmental phases from the Saalian late glacial to the Weichselian pleniglacial in central Europe—Insights from a lacustrine succession in Lichtenberg, northern Germany

Boreas, EarlyView.
Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.
