Paleoceanography and Paleoclimatology, Volume 41, Issue 10, October 2026.Abstract Although foraminiferal oxygen isotope records (δ18OF) have long been used to develop time‐continuous estimates of past global ice volume, growing evidence indicates that the ice volume and temperature contributions to δ18OF diverge considerably over the last glacial cycle.

Paleoceanography and Paleoclimatology, Volume 41, Issue 10, October 2026.Abstract Reconstructing past interactions between the West Antarctic Ice Sheet (WAIS) and changing environmental conditions in the Ross Sea region can help determine long‐term WAIS stability. Existing sedimentary records reveal changes to oceanography, sea ice and ice sheet extent over the glacial‐interglacial cycles of the last ∼800 kyr.

AMS RADIOCARBON DATES OF KURGANS LOCATED ON THE UST-YURT PLATEAU, UZBEKISTAN
, 2005 Recent osteological analyses of archaeological human skeletal remains from the Ust-Yurt Plateau, Uzbekistan, provided the opportunity to obtain samples for radiocarbon dating. The results of 18 accelerator mass spectrometry (AMS) dates are presented in

Target Capture of Ancient Shell DNA Enables Phylogenetic Reconstruction of Deep‐Sea Molluscs
Molecular Ecology Resources, Volume 26, Issue 7, October 2026.ABSTRACT Target capture is widely used to enrich endogenous DNA from calcium phosphate skeletal material in vertebrates, but its performance on calcium carbonate hard parts widely produced by invertebrates remains poorly understood. Here, we compared DNA recovery from four fresh and 12 ancient (eight radiocarbon‐dated to 1671–1135 years old before ...

U. S. Geological Survey radiocarbon dates, [Part] 5.
, 2013 The dates listed herein have been determined at the U.S. Geological Survey radiocarbon laboratory at Washington, D.C., since the last date list (U.S.G.S. IV, 1958) and up to the end of 1959. Acetylene continues to be the gas chosen.

Application of Multi‐Method Dating for Understanding the Gravettian North of Moravia, Central Europe
Archaeometry, Volume 68, Issue 5, Page 1050-1061, October 2026.ABSTRACT This article presents the results of integrating three methods to assess the age of the Upper Palaeolithic site of Pietraszyn 11 (SW Poland), close to the Moravian Gate. Sediment chronology determined using optically stimulated luminescence produced promising, yet ambiguous results (51.0 ± 3.7 to 20.3 ± 0.7 ka).

New radiocarbon dates of the North Asian steppe zone and its consequences for the chronology.
, 2001 The chronological problems of the Steppe zone have been under intensive investigation during the last years but no generally accepted chronological system existed up to now. We present new radiocarbon dates of samples from several excavation sites.

Early Bronze Age Copper Circulation in the Guadalentín and Segura Valleys (SE Spain)
Archaeometry, Volume 68, Issue 5, Page 1139-1151, October 2026.ABSTRACT Identifying the sources of copper used in Early Bronze Age metalwork from south‐east Spain is key to resolving a long‐running debate concerning centralized control, or lack thereof, over El Argar society's economic organisation. This study provides the first substantial integrated programme of EDXRF and MC‐ICP‐MS analyses for copper‐base ...
