A Machine Learning Framework for Retrieving Atmospheric Composition and the Associated Averaging Kernels From a Geostationary Hyperspectral Infrared Sounder

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Geostationary hyperspectral infrared sounders provide hourly observations of the atmospheric composition. However, the conventional optimal estimation method (OEM)‐based retrieval algorithm requires computationally expensive radiative transfer calculations and inverse modeling, making it difficult to monitor in real time. This study presents a

A Time‐Calibrated Phylogeny and Historical Biogeography of Leptoceridae (Trichoptera): Diversification Shaped by Gondwanan Fragmentation and Conflicting Evidence for the Family's Origin

open access: yesJournal of Biogeography, Volume 53, Issue 10, October 2026.
ABSTRACT Aim Leptoceridae is the second most diverse caddisfly family, spreading across all biogeographical regions but with a higher species richness in the Oriental region; nevertheless, the Afrotropical, Austral and Neotropical regions have greater genera diversity and endemicity.

The Unexpected Discovery of Paleocene? Coals in Outcrops Thought to Be Cambrian, Al Huqf, Oman

open access: yesJournal of Petroleum Geology, Volume 49, Issue 4, Page 1179-1194, October 2026.
ABSTRACT Two brown organic deposits were encountered whilst investigating kaolinitic claystones thought to occur at the base of a Cambrian formation at outcrop. The age of these organic deposits is probably Paleocene from palynology. Organic petrography shows that they are subbituminous coals with some oil source potential.

Spatial and temporal evolution of a coastal erg margin: The Middle Jurassic Page Sandstone, southern Utah, USA

open access: yesSedimentology, Volume 73, Issue 6, Page 2081-2119, October 2026.
ABSTRACT Aeolian deflationary events are erosive to static stages where sediment supply is insufficient to support bedform migration and preservation in the rock record. In the vicinity of shallow‐marine environments, inland rises of relative water table and associated generation of deflationary super surfaces may be driven by the onset of ...

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 ...

A Triassic chronostratigraphic and palaeogeographic framework for the Utsira High area, northern North Sea: Reconstructing a basin‐scale drainage divide

open access: yesSedimentology, Volume 73, Issue 6, Page 2417-2453, October 2026.
ABSTRACT The Triassic succession of the northern North Sea comprises a series of interbedded sandstones, mudstones and conglomerates deposited under a fluctuating arid to semi‐humid climate regime, which are often difficult to correlate regionally due to differing lithostratigraphic schemes and poor age control. Despite existing regional studies on the
