Early to Mid‐Holocene molluscan community dynamics in Billefjorden, central Svalbard: the interplay of local geomorphology and regional climate

Boreas, EarlyView.
The postglacial evolution of High Arctic coastal environments is recorded in the rich fossiliferous archives of raised marine terraces. This study employs a multi‐proxy approach combining molluscan community analysis, taphonomy and sedimentology to reconstruct the Early to Mid‐Holocene environmental dynamics of the Mimerdalen embayment in the ...

The last glacial cycle in western Norway—extensive MIS 5d glaciation, multiple glacial advances and LGM glacial advance phases

Boreas, EarlyView.
Raised marine MIS 5c sediments evidence extensive preceding (5d) glaciation in western Norway. This is the first out of five (or six) major Weichselian glacier advances that seem to correspond to North Atlantic sea surface cooling periods. Till beds capping the marine sediments show stages of pre‐LGM advance and subsequent retreat.

Lead isotope evidence for Antarctic Ice Sheet changes in the Weddell Sea sector since the Last Glacial Maximum

Boreas, EarlyView.
The Weddell Sea influences global ocean circulation and sea level through modulating Antarctic Bottom Water formation and Antarctic Ice Sheet discharges, but the history of ice‐sheet dynamics in this region remains poorly constrained due to limited well‐dated geological records.

Formation of clastic sediments in the Atl cave of the Sierra Zongolica, Veracruz Mexico, and their relationship to the soil cover

Acta Carsologica
Allochthonous cave sediments contain important paleontological and archaeological records as well as indicators of recent ecological processes. Correct interpretation of these records requires knowledge about the sediment sources and deposition processes,

Best Practices in Open and Reproducible Antarctic Marine Sediment Core Research

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract Marine sediment cores from Antarctica are archived by national programs for reuse and resampling by future researchers, creating a resourceful way to conduct Antarctic science. With reduced budgets to conduct Antarctic field work and to collect new sediment cores offshore of the icy continent, the accessibility of these archived cores and ...

Quantifying user variability in the traditional X‐ray ice‐rafted‐debris counting technique

Journal of Quaternary Science, Volume 41, Issue 7, Page 1048-1059, October 2026.
ABSTRACT The flux of icebergs is most commonly constrained in the palaeo‐record by manually counting gravel clasts in sediment core X‐ray images—a trusted method in Quaternary science and palaeoceanography for nearly 40 years. In this study, we explore the reproducibility (user consistency and between‐user variability) of the traditional clast‐counting

Decoupling glacier retreat and surface stabilization on the Snežnik Plateau (Slovenia), insights from in situ cosmogenic 36Cl exposure and depth‐profile ages

Journal of Quaternary Science, Volume 41, Issue 7, Page 1060-1077, October 2026.
ABSTRACT Glaciokarst landscapes pose distinctive challenges for cosmogenic dating because meltwater and runoff can be rapidly rerouted into ponors and conduit networks, weakening glacier–river coupling and promoting local sediment storage. We reconstruct glacier retreat and postglacial stabilization on the Snežnik Plateau (SW Slovenia) using in situ ...

Before the winter came: The Early Pleistocene pre-glacial history of the Baltics illuminated by facies analysis and cosmogenic nuclide dating of borehole cores from Lithuania (NE Europe)Mendeley Data

Quaternary Science Advances
Understanding the evolution of past ice sheets is essential for comprehending Earth's climate and improving its prediction. However, information about the oldest Quaternary continental glaciations is scarce due to preservation limitations and ...

Lodge moraines: a common yet underreported end‐moraine type—a review

Boreas, Volume 55, Issue 4, Page 906-931, October 2026.
Lodge moraines are a distinct genetic type of end moraine formed by submarginal accretion of subglacial till; they are some of the largest end moraines in the world. Although underreported in the literature, they are of equal importance to push, dump and hummocky end moraines. End moraines are formed at glacier ice margins and show the extent of former

Early evidence of Acheulean settlement in northwestern Europe--la Noira site, a 700,000 year-old occupation in the center of France.

PLoS ONE, 2013
The human settlement of Europe during Pleistocene times was sporadic and several stages have been recognized, both from paleaoanthropological and archaeological records.
