New Insights Into Hikurangi Subduction Inputs and Megathrust Host Rocks Spanning Along‐Margin Changes in Fault Slip Behavior

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The seismic behavior of subduction megathrusts varies spatially and is influenced by the properties of subducting plates, including their sedimentary cover. Characterizing these subduction inputs is essential for understanding the mechanisms behind fault slip variability.

Evidence for Limited Atmospheric CO2 Rise at the Miocene Climatic Optimum

Paleoceanography and Paleoclimatology, Volume 41, Issue 6, June 2026.
Abstract The Miocene Climatic Optimum (MCO; 16.9–14.7 Ma) was a relatively warm period with atmospheric CO2 averaging ∼500 μatm but CO2 change across its onset is poorly documented. We present a record of algal 13C‐fractionation covering the Early to Middle Miocene (∼18.5–15 Ma), with a gap at the MCO onset, from Ocean Drilling Program Site 959 in the ...

Morphological abnormalities in benthic foraminifers of the Antalya coast

Micropaleontology, 2008
Many researchers report abnormal testmorphologies in benthic foraminifers and some suggest that anthropogenic pollutionmay be one of the causes for these anomalies. Some species are even used as bioindicators of anthropogenic pollution. However, environmental stress may be exerted by natural factors also, such as hypersalinity, periodical acidification

Bioerosion Drill Holes Increase Carbonate Dissolution in the Planktonic Foraminifer Globigerinoides ruber

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Planktonic foraminifera are instrumental in reconstructing paleoceanographic and paleoclimatic conditions. However, preferential dissolution can significantly bias both assemblages and chemical analyses, leading to biased interpretations. Bioerosional drill holes are commonly found in foraminiferal tests; however, it remains unknown if these ...

Spatial and Temporal Variability of Eastern Pacific Radiocarbon and Carbon Chemistry From the Ice Age to Today

Paleoceanography and Paleoclimatology, Volume 41, Issue 5, May 2026.
Abstract Proxy records of seawater radiocarbon (14C/C) provide strong constraints on how changes in ocean ventilation contributed to the increase in atmospheric CO2 during the termination of the last ice age (≈18,000‐to‐12,000 years ago). One outstanding problem, however, is the existence of anomalously low deglacial benthic foraminiferal 14C/C in the ...

Intensified Meltwater Influx During Heinrich Stadial 1 Recorded in the Gulf of Maine, USA

Paleoceanography and Paleoclimatology, Volume 41, Issue 5, May 2026.
Abstract Abrupt, millennial‐scale climate events characterize the most recent deglaciation. However, their nature remains poorly understood. Previous work has shown enhanced glacial melt signals from the European/Scandinavian Ice Sheet and a rapid recession of the Laurentide Ice Sheet (LIS) in Eastern Maine during Heinrich Stadial 1 (HS‐1).

Type of Carbonate Production, Sedimentary and Tectonic Evolution of the Pliocene Mixed Carbonate Siliciclastic Unit (Macco) in the Tarquinia Basin, Central Italy

Basin Research, Volume 38, Issue 3, May–June 2026.
Piacenzian mixed carbonate‐siliciclastic succession (‘Macco’ unit) deposited on the passive margin of the Tyrrhenian back‐arc basin. Sedimentation was controlled by syn‐sedimentary tectonics, with NW–SE first‐order faults (3–4 km) creating accommodation space and NE–SW second‐order faults (~0.5 km) influencing facies distribution and growth structures.

Depositional Setting of Eastern Sakarya Zone (NE Türkiye): Late Cretaceous–Paleogene Period Biostratigraphy, Sedimentology and Tectono‐Sedimentary Basin Evolution

Basin Research, Volume 38, Issue 3, May–June 2026.
K‐Pg transition and Maastrichtian stage of sedimentary basin evolution of the Eastern Sakarya Zone. ABSTRACT This study reconstructs the late Campanian–Thanetian tectonic and sedimentary evolution of the Eastern Sakarya Zone Basin (Türkiye) during the closure of the Neotethys Ocean, through the integration of tectonic, biostratigraphic and sedimentary ...

Stratigraphic potential of the Upper Triassic benthic foraminifers

Albertiana, 2010
A succession of unusually rich, well-preserved and diversified Carnian-Norian benthic foraminiferal assemblages has been found in an isolated limestone remnant of the Panthalassa Ocean (Black Marble Quarry, Wallowa terrane, Oregon). Foraminifers, including about 75% of well-known Tethyan species, show there a comparable stratigraphic distribution with ...

Environmental Contamination Affects Associated Bacterial Communities in a Neotropical Arboreal Ant

Biotropica, Volume 58, Issue 3, May 2026.
Environmental stressors such as contamination from mining tailings can alter microbial communities associated with insects, including social ants. Ants, as widespread and ecologically influential insects with stable microbial associations, offer a relevant model to examine these effects.
