Lower Glacial Oxygen in the Eastern Equatorial Pacific Concentrated in the Deep Sea

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Oxygen in the global oceans has declined since the 1960s, including in the Eastern Equatorial Pacific (EEP). Reconstructions of EEP glacial oxygenation help advance understanding of current and projected ocean deoxygenation. Previous estimates of the glacial oxygen deficient zones (ODZs) in the upper EEP are poorly constrained. Here we include

The Use of Micro‐CT Analysis of the Second Metacarpal to Assess Cortical Bone Loss in Archeological Human Skeletal Remains

American Journal of Biological Anthropology, Volume 189, Issue 2, February 2026.
ABSTRACT Objectives The assessment of cortical bone loss in archeological populations can give insights into past lifeways and bone health. The second metacarpal index (MCI) is assessed via radiogrammetry to quantify cortical thickness. However, as this method is limited to a single‐point measurement, this study explores the use of micro‐computed ...

Polygonal tepee structures of Arabia

The Depositional Record, Volume 12, Issue 1, February 2026.
Tepee structures on Sheybarah Island form polygonal microbial cemented crusts in the intertidal. Radiocarbon dating suggests they formed in the Holocene and reflect minor sea‐level changes, highlighting their value as palaeoenvironmental indicators. Satellite surveys identified 126 polygonal features, including coral reefs that may have developed on ...

Enhancing event stratigraphic correlations in the ultra‐deep Japan Trench using XRF‐CS cluster‐based chemostratigraphy

The Depositional Record, Volume 12, Issue 1, February 2026.
Cluster‐based chemostratigraphy using XRF‐CS enables high‐resolution correlation of event deposits across contrasting depositional settings in the Japan Trench. This approach reveals previously unrecognised events and compositional heterogeneity, offering new insights into sediment provenance and earthquake‐triggered deposition, with implications for ...

Laguna Fuente de Piedra: An example of a dolomite factory recording ~50,000 years of depositional and paleoclimatic evolution

The Depositional Record, Volume 12, Issue 1, February 2026.
This study characterises carbonate mineral precipitation mechanisms and their paleoenvironmental implications in a semi‐arid, saline playa lake system. SEM image with EDS spectra shows microcrystalline, spherical shaped dolomite crystals from Laguna Fuente de Piedra composed of nanocrystals with bacterial voids and EPS.
