Seasonal Changes in Marine Archaeal Tetraether Lipid Export Depth Linked to Net Primary Productivity

Paleoceanography and Paleoclimatology, Volume 41, Issue 2, February 2026.
Abstract Marine ammonia oxidizing archaea (AOA) produce isoprenoid glycerol dibiphytanyl glycerol tetraethers (GDGTs) which form the basis of seawater temperature proxy TEX86. Although most studies use TEX86 for sea surface temperature (SST) reconstructions, maximum GDGT production occurs at and below the nitracline. Moreover, sedimentary GDGT‐2/GDGT‐3

Revised History of Pleistocene Vertical Motions in NE Sicily and Southern Calabria, Italy, From 40Ar/39Ar Dating and Fault Zone Morphology

Tectonics, Volume 45, Issue 2, February 2026.
Abstract Long‐term rates of crustal uplift in southern Calabria and NE Sicily are incompletely understood due to limited information about the age of marine terraces at 1.0–1.3 km above sea level (asl). This study provides a new constraint on high‐elevation terrace ages through integrated analysis of geochronology, stratigraphy, shoreline modeling, and

Micrography and XRF Techniques to Investigate Protohistoric Gold Artifacts: The Case of Roca Vecchia (Lecce, Italy)

Archaeometry, Volume 68, Issue 1, Page 51-63, February 2026.
ABSTRACT Protohistoric gold findings from the archaeological site of Roca Vecchia (Melendugno, Lecce, Italy) are analyzed involving micrography and stratified XRF analysis. This exploitation allows to get a deeper insight into ancient gold manufacturing and wear processes adopted in the Southern Italian FBA.

Pan‐Arctic Peatlands Have Expanded During Recent Warming

Global Change Biology, Volume 32, Issue 2, February 2026.
Arctic peatland carbon is important because it represents a large carbon stock that may be vulnerable to climate change. This work explores the expansion and/or shrinkage of Arctic peatlands using observations in two north–south transects in Canada and in Europe.

BURIED ORNAMENTS: EXPLORING FUNERARY BEHAVIOURS IN THE CHALCOLITHIC FROM THE LOWER DANUBE

Oxford Journal of Archaeology, Volume 45, Issue 1, Page 2-27, February 2026.
Summary This article focuses on personal adornments found in Chalcolithic funerary contexts from the Lower Danube. Generally, these artefacts are made from exotic raw materials originating from the Mediterranean sea, particularly Spondylus shells, along with Glycymeris or Antalis shells, and less frequently from local materials.
