Cet article est une étude expérimentale menée sur le site archéologique de Gasr Chouline à Tataouine en utilisant la prospection archéologique et les systèmes d'informations géographiques (SIG) pour améliorer la gestion du site. Bien que cette étude n'ait pas prétendu à l'exhaustivité, elle a fourni de nouvelles données archéologiques par suite d'une prospection systématique.

This paper outlines the ways in which the project is addressing the colonial legacy of Henry Wellcome as well as presenting the data from the first three field seasons at Jebel Moya, south-central Sudan. These data have substantially revised our chronological and socio-economic understanding of the site. Our excavations, initiated in 2017 and continued in 2019 and 2022, show a longer, more continuous occupation of the site than has been previously recognised. The faunal and botanical remains have implications for the spread of early domesticates in the eastern Sahel and for climate changes, and raise issues of resilience. There is confirmed human burial activity from at least the third millennium BC onwards, while the pottery continues to yield information about the variety of decoration and, for the final Assemblage 3, data on its usage. Overall, the continued importance of the site for the eastern Sahel is re-emphasised.

This study explores the impact that recent Bronze Age hoard finds have had on our understanding of hoarding practices across Britain and Northern Ireland. Changes to the legislation of Treasure and the onset of the Portable Antiquities Scheme in England and Wales have produced a wealth of new information on Bronze Age hoards. Beyond a handful of studies which have focused on specific groups of hoards or the distinction between dryland/wetland deposition, however, many of these more recent finds have been overlooked. Our regional understanding of hoarding practices across Britain is also largely based on studies which are now significantly out of date. This paper aims to address this problem by providing a snapshot of hoards and hoarding practices, based on a substantial dataset of 385 hoards (containing 7210 objects) that were reported on between 1997 and 2021. Broad chronological and spatial trends in the distribution are highlighted, with precedence given to characterising these enigmatic deposits based on their size and the categories of objects within them. This investigation provides fresh insights into the selection of certain object groups – particularly axes – during certain periods and within specific regions, whilst also exploring ideas so that we might better understand the scale of metalwork deposition. This research not only demonstrates how recent hoard finds fit into traditional narratives but also how they have the potential to enhance our understanding of regional hoarding practices, offering new and exciting avenues for future research.

This study utilizes speleothem trace elements as climate proxies to reconstruct hydroclimate variability over approximately 350 years in the Southern Cook Islands. Stalagmites Pu17 and Pu4 from Pouatea cave were analyzed using high-resolution LA-ICP-MS for trace elements (Mg, Na, Sr, P, U, Y). By monitoring cave dripwater and conducting regression analysis, we found that Mg, Sr, and Na in Pouatea dripwater mostly originated from marine aerosols, while Sr and Ba were primarily from bedrock, with additional Ba coming from marine aerosols and weathered oceanic basalt leaching. Mg was identified as the most reliable element for hydroclimate reconstruction due to its predominantly marine aerosol origin. Infiltration, via dilution of marine aerosols and bedrock inputs, was identified as the main driver of trace element variations in Pouatea at a seasonal scale. Transfer functions were established between each trace element and effective infiltration was calculated, with Mg showing the strongest correlation. The reconstructed infiltration data were compared with climate indices, showing an overarching role of the SPCZ and ENSO in controlling rainfall in the South Pacific. This research demonstrates the potential of speleothem trace elements for paleohydroclimate reconstructions, improving understanding of rainfall variability in the climatically vulnerable South Pacific Islands over the past millennia.

The rich architectural heritage of Cyprus from the period of Byzantine and Latin rule includes 10 churches inscribed in the UNESCO World Heritage list. Most of these monuments preserve wooden elements: whether structural, decorative or furnishings. Many preserve wall paintings that are considered among the best examples of Byzantine and Medieval art in the Eastern Mediterranean. The dating of these paintings as well as the church buildings themselves, has been based mainly on style, with occasional dedicatory inscriptions and related historical interpretation. We report early results from a project investigating the wooden cultural heritage of Cyprus and in particular the combined use of dendrochronology with radiocarbon via tree-ring sequenced 14C wiggle-matching to help place initial tree-ring sequences. This includes a floating 264-year Pinus brutia chronology from several monuments, which, with a ca. 5-year gap, suggests prospects for >700-years of P. brutia chronology for Cyprus, and, with one gap of several decades to fill, ca. 1100 years of Pinus nigra chronology for Cyprus. Several currently floating elements from the multi-phase UNESCO-listed Timios Stravros church at Pelendri, including a terminus post quem for the celebrated liturgical wooden cross, are approximately dated across the 11th to 16th centuries AD.

In-situ cosmogenic 10Be (and 26Al) concentrations in alluvial sediments provide a spatially averaged signal of the erosion rate of the catchment area. Catchmentwide erosion rates reflect the production rate of the entire basin, and their calculation requires knowledge of the complete production rate model. Available calculators determine production rates on a pixel-based approach and achieve computational efficiency by relying on a scaling method that ignores geomagnetic field strength variations. Here we introduce a new python-based tool that determines erosion rates based on the hypsometry of the catchment. The method relies on the fact that production rates are much more sensitive to changes in elevation than latitude. Our tool has two main advantages: (1) computation time is short (<30 seconds) and independent of the scaling method; there is no need to neglect magnetic field variations, and (2) because production rate scaling is performed by a widely used online calculator, the results are fully comparable to exposure ages or point-based erosion rates determined with the same calculator; future updates to production rate scaling are immediately effective for catchmentwide erosion rate calculation. We demonstrate in two case studies that (1) for similar scaling methods, our calculator reproduces pixel-based results within a few percent, and (2) erosion rates determined with different scaling methods may differ by >20%, differences can vary systematically with erosion rate, and using a time-constant scaling method may result in a bias in the interpretation of catchmentwide erosion rates.
