Outcrop and subsurface characterisation of a mixed tidal and wave‐influenced coastline (Triassic Red Beds, SE Spain)

open access: yesSedimentology, Volume 73, Issue 6, Page 2381-2416, October 2026.
ABSTRACT Paralic depositional systems are complex and heterogeneous sedimentary environments, presenting challenges for predicting reservoir architecture and connectivity. Their stratigraphic and facies variability arises from the dynamic interplay between fluvial, tidal and wave processes, and their sensitivity to sea‐level fluctuations, sediment ...

Cryogen‐Aided Chromatographic Purification of Millimole Quantities of Methane for Spectroscopic Clumped Isotope Analysis

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 18, 30 September 2026.
ABSTRACT Rationale Quantum cascade laser absorption spectroscopy (QCLAS) is a fast and reliable method for analyzing the bulk (𝛿13C‐CH4, 𝛿D‐CH4) and clumped isotopic (∆13CH3D and ∆12CH2D2) composition of methane. However, precise measurements of ∆12CH2D2 require 0.5 to 1.8 mmol of purified methane (equivalent to 15 to 40 mL at STP).

Meteorological and Emission Drivers of Compound Heat and Ozone Pollution Episodes in Oklahoma City During Periods Influenced by Atlantic Tropical Cyclones

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Compound heat and ozone (O3) pollution events are widespread and pose significant health risks in urban areas. In the Southern Great Plains (SGP), where heat waves are becoming more frequent and intense, these compound events represent a growing environmental and public health concern, underscoring the need for improved process‐based ...

Associations of Outdoor Air Pollution With Incidence of Cancers Other Than Lung Cancer in a Large US Prospective Cohort

open access: yesInternational Journal of Cancer, Volume 159, Issue 6, Page 1440-1454, 15 September 2026.
Associations between outdoor air pollution and cancers other than lung cancer remain unclear, particularly in the context of tobacco use. Here, the authors assessed possible links between ambient air pollutant exposure and incidence of 20 non‐lung cancers among adults followed over a 25‐year period in the United States.
