Subglacial Lake Discharge Affects the Age and Concentration Distribution of Dissolved Organic Carbon in Ross Sea Surface Waters

AGU Advances, Volume 7, Issue 5, August 2026.
Abstract The Ross Sea continental shelf plays a key role in the global carbon cycle. However, the sources and cycling of dissolved organic carbon (DOC) in the region are poorly understood. Here, we determined the radiocarbon (14C) and stable carbon isotope (13C) contents of DOC in addition to those of dissolved inorganic carbon (DIC) in the Little ...

The loss of an Indigenous‐maintained She‐Oak woodland in southeast Australia

Geographical Research, Volume 64, Issue 3, August 2026.
A 2600‐year multi‐proxy palaeoecological record (pollen, charcoal, and sediment) from Balfour Swamp, east Gippsland, reveals the persistence of an open, grassy She‐Oak woodland maintained by GunaiKurnai. This vegetation community, resilient to climatic variability and fire, was lost following the disruption of Aboriginal land management and replaced by

Fecal Steroids as Tracers of Human Population and Waste Management Practices at the Ancient Maya City of Ucanal, Guatemala

Archaeometry, Volume 68, Issue 4, Page 646-658, August 2026.
ABSTRACT Geochemical data compiled from dried sediments from three water reservoirs at the ancient Maya city of Ucanal, Petén, Guatemala, reveal low to undetectable fecal biomarker concentrations. These low concentrations may be the result of the aerobic decay of sterols combined with well‐managed waste disposal practices.

Ring‐Width Dendrochronology, Isotopic Dendrochronology and Radiocarbon Dating of Timbers From the Spire Scaffold of Salisbury Cathedral, Wiltshire, England

Archaeometry, Volume 68, Issue 4, Page 761-772, August 2026.
ABSTRACT Ten timbers from the spire scaffold of Salisbury Cathedral were dated using a combination of ring‐width dendrochronology, stable oxygen isotopic dendrochronology and radiocarbon dating. Seven timbers were coeval and assigned a combined empirical felling date range of 1352–1378, which was further refined to 1351–1359 (OxCal 95.4%).

Navigating the Flames: Comparative Analysis of Cremation Practices in the Roman and Early Medieval Periods at Gbely‐Kojatín (SK) and Přítluky (CZ)

Archaeometry, Volume 68, Issue 4, Page 818-830, August 2026.
ABSTRACT Cremation became the dominant funerary practice in the Middle Danube Region during the Roman Period (RP) (1st–4th century) and reappeared in the Early Medieval Ages (EMA) (6th/7th–8th century). This study aims to reconstruct differences in cremation conditions from the Gbely‐Kojatín site (Slovakia, RP and EMA) and the Přítluky site (Czech ...

Radiocarbon calibration and age estimation

, 2019
Radiocarbon dating can be applied to archaeological materials which contain radiocarbon from the atmosphere or the oceans. In order to interpret radiocarbon measurements as dates, it is necessary to compare them against measurements on known‐age samples which have been dated by other methods. This allows calibration onto a timescale derived from either

An Archaeometric Approach to Reveal Organic Compounds via GC‐MS Analyses of Two Discovered Incense Burners at Daba Al‐Bayah

Archaeometry, Volume 68, Issue 4, Page 804-810, August 2026.
ABSTRACT This study focuses on two terracotta incense burners discovered in the Daba Al‐Bayah necropolis in the Musandam Peninsula (Oman), associated with an Iron Age collective tomb (LCG‐2). Through gas chromatography–mass spectrometry (GC‐MS), the organic residues preserved within these artifacts were analyzed to investigate their use and ...

Dealing With Inbuilt Age: A Bayesian Approach to Radiocarbon Dating of Rice, Bamboo and Charcoal From Non Ban Jak, Thailand

Archaeometry, Volume 68, Issue 4, Page 811-817, August 2026.
ABSTRACT New radiocarbon determinations from rice grains and bamboo have been obtained from Non Ban Jak, Northeast Thailand. These, along with charcoal, date a late Iron Age building sequence. The results come from short‐lived species and charcoal with potential inbuilt age. We built a series of Bayesian models to obtain a reliable chronology.
