Discovery of Triassic phylloid algae: possible links with the Paleozoic
, 1986 Triassic phylloid algae have recently been discovered in a reef in the southern Yukon. These plate-like algae are the primary frame builders in a few small patches in the upper section of the reef, where they are associated with fossils and sedimentary ...

Magnitudes and Rates of Strength‐Drawdown Modulate Injection‐Induced Seismicity
Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.Abstract Accurately forecasting injection‐induced seismicity remains a major challenge that is critically important for energy production and storage as controlling mechanisms are complex and remain opaque. We clarify key processes by following time‐histories of bespoke parameters anticipated to control strength reduction (drawdown) through ...

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.Abstract Aqueous‐phase reactions are hypothesized to be a major pathway for secondary organic aerosol (SOA) formation in humid, cloud‐influenced environments, yet direct observational constraints remain limited. Here we investigated aqueous SOA (aqSOA) formation and evolution during the spring 2016 Holistic Interactions of Shallow Clouds, Aerosols, and

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract The timing of Cenozoic deformation in the East Kunlun Mountains, northern Tibet, is crucial for understanding plateau growth but remains disputed due to the scarcity of direct chronological constraints on specific tectonic structures. Here, we present a high‐density‐sampling magnetostratigraphic record from the Xiaohongshan section, interior ...

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract Extratropical cyclones strongly influence Arctic sea ice thermodynamics through episodic heat and moisture transport, yet their thickness‐dependent impacts remain poorly quantified. Using comprehensive observations from the Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC), we investigate how sea ice thickness ...

The SPICE carbon isotope excursion in Siberia: a combined study of the upper Middle Cambrian-lowermost Ordovician Kulyumbe River section, northwestern Siberian Platform [PDF]
, 2008 An integrated, high-resolution chemostratigraphic (C, O and Sr isotopes) and magnetostratigraphic study through the upper Middle Cambrian–lowermost Ordovician shallowmarine carbonates of the northwestern margin of the Siberian Platform is reported. The
