Terrestrial Ecosystem Response to Changing Temperature and Seasonality in the Paleocene‐Eocene Thermal Maximum: Shallow Marine Records From the Salisbury Embayment, USA

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 3, March 2026.
Abstract The Paleocene‐Eocene thermal maximum (PETM, ∼56 Ma) is marked by a massive and rapid rise in atmospheric CO2 and ∼5°C of global warming. It is globally characterized by a negative carbon isotope excursion (CIE), and, at least locally, is preceded by a pre‐onset excursion (POE).

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

open access: yesTectonics, 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

Relationship and Source of Whitings Used as a Painting Ground in Icons From Polish Museum Collections Based on Their Calcareous Nannofossil Content

open access: yesArchaeometry, Volume 68, Issue 1, Page 132-143, February 2026.
ABSTRACT In icon painting, chalk whiting is key to creating a gesso ground, providing a smooth, absorbent surface for paint. Calcareous nannofossils, tiny marine skeletons found in chalk, are an ideal tool for analyzing the origin of an icon's chalk ground, often the only reliable information about where the icon came from.

Sea Surface Temperature and Salinity Changes in the Easternmost Mediterranean During the Pre‐Evaporitic Messinian Controlled by the Restriction at Gibraltar

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 1, January 2026.
Abstract During the latest Miocene, the Mediterranean Basin was affected by extreme paleoceanographic and paleoenvironmental changes culminating with evaporite (gypsum and halite) formation during the Messinian Salinity Crisis (MSC: 5.97–5.33 Ma).
