Facies analysis provides new insights into event bed deposition in a hadal trench environment

Sedimentology, Volume 73, Issue 2, Page 441-477, February 2026.
ABSTRACT Hadal trenches preserve exceptional sedimentary archives of past geological events, yet their depositional processes remain poorly constrained. The Japan Trench captures complex earthquake‐triggered event beds that record repeated sediment‐gravity flows that deliver terrigenous and biogenic material into the trench, informing palaeoseismic ...

Modeling the Impact of Alternative Fuels and Hydrogen Propulsion on Contrail‐Cirrus: A Parameter Study

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 2, 28 January 2026.
Abstract Line‐shaped contrails formed behind aircraft can evolve into broadly spread and long‐living cirrus clouds under favorable conditions. These contrail‐cirrus contribute significantly to the aviation‐induced radiative forcing. While past modeling studies have examined contrail‐cirrus across various atmospheric and aircraft‐type dependent ...

Experimental observation of parabolic wakes in thin plates

Physical Review Research
Wakes are medium perturbations created by a moving object, such as wave patterns behind boats, or wingtip vortices following an aircraft. Here, we report about an experimental study of an uncharted form of parabolic wakes occurring in media with the ...

Removal and mixing of the coronal gas from satellites in galaxy groups: cooling the intragoup gas

, 2012
The existence of an extended hot gaseous corona surrounding clusters, groups and massive galaxies is well established by observational evidence and predicted by current theories of galaxy formation.

Spectral Analysis of Confined Cylinder Wakes

Fluids
Bluff body flows, while commonly assumed to be isolated, are often subject to confinement effects due to interactions with nearby objects. In this study, a simple approximation of such a flow configuration is considered, where a cylinder is placed ...

Body Motion Under an Ice Cover in the Presence and Absence of Ocean Waves

Journal of Marine Science and Engineering
This study investigates the unsteady motion of a slender body in a fluid beneath an ice cover, both in the presence and absence of the ocean waves propagating through the ice–water system, using the Fourier and Laplace integral transforms.

Unsteady Secondary Flow Structure at a Large River Confluence

Water Resources Research
River confluences, which are characterized by complex hydrodynamics, are key nodes for flood control and environmental protection. Two field surveys were carried out at the confluence of the Yangtze River and Poyang Lake to investigate the transient ...
