Contrasting Responses of Dissolved Oxygen in the Northern Benguela Upwelling System to Four Decades of Warming

Journal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract The Northern Benguela Upwelling System (NBUS) is a highly productive yet low‐oxygen region, influenced by the combined effects of circulation and biogeochemical processes. Using data from a high‐resolution (∼7 km) coupled physical–biogeochemical model spanning 1980–2020, this study investigates long‐term dissolved oxygen (DO) variability in ...

Investigation of behavior of the dynamic contact angle on the basis of the Oberbeck-Boussinesq approximation of the Navier-Stokes equations

MATEC Web of Conferences, 2016
Flows of a viscous incompressible liquid with a thermocapillary boundary are investigated numerically on the basis of the mathematical model that consists of the Oberbeck-Boussinesq approximation of the Navier-Stokes equations, kinematic and dynamic ...

The Structure and Lifecycle of Stratified Mixing by Shear Instabilities in Continuously Forced Flows

Journal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract The turbulent energy cascade of ocean mixing remains poorly understood at geophysically large Reynolds numbers (Re $\mathrm{R}\mathrm{e}$). Here we propose a new conceptual model for the structure of small‐scale mixing grounded in high‐resolution multibeam echosounding observations from the mouth of the Connecticut River, a shallow salt‐wedge ...

Thermal dissipation of two-step combustible tangent hyperbolic fluid with quadratic Boussinesq approximation and convective cooling

Results in Materials
This study explores thermal criticality and dissipation involving a two-step reaction in a hyperbolic tangential fluid flow and quadratic Boussinesq approximation to model the complex internal heat transfer mechanisms during combustion.

How Does Ice Shell Geometry Shape Ocean Dynamics on Icy Moons?

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract A poleward‐thinning ice shell can drive circulation in the subsurface oceans of icy moons by imposing a meridional temperature gradient–colder at the equator than the pole–through the freezing point suppression due to pressure. This temperature gradient sets a buoyancy gradient, whose sign depends on the thermal expansion coefficient ...

Effect of Alongshore Aquifer Property Changes on the Steady‐State Extent of Seawater in Coastal Aquifers: Analytical Derivation and Numerical Validation

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract The spatial variability in coastal aquifer hydraulic properties significantly affects the extent of seawater and its movement. Yet, previous analytical solutions have almost exclusively evaluated only homogeneous and stratified aquifers. This study derived analytical solutions for the steady‐state, sharp‐interface seawater extent in two ...

Interface Deformation, Exhumation, and Underplating: The Role of Plate Velocity Changes Throughout the Evolution of a Subduction Zone

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Exhumed metamorphic rocks yield critical insights into the mechanical, chemical, and thermal structure of the plate interface that can be used to infer exhumation pathways and their evolution throughout a subduction zone's lifetime. Metamorphosed oceanic rocks often record exhumation and underplating over relatively punctuated time periods ...

Beyond Equilibrium: Kinetic Thresholds and Rheological Feedbacks Create a Potentially Complex 410 in Slab Regions

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract The seismic expression of Earth's 410 km discontinuity varies across tectonic settings, from sharp, high‐amplitude interfaces to broad transitions—patterns that cannot be explained by equilibrium thermodynamics without invoking large‐scale thermal or compositional heterogeneities.

Couette-Hiemenz exact solutions for the steady creeping convective flow of a viscous incompressible fluid with allowance made for heat recovery

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2018
In this paper, we study the steady creeping convective flow of a viscous incompressible fluid in the thin infinite layer. The study of the fluid flow is based on the exact solutions class for the Oberbeck-Boussinesq equations in the Stokes approximation ...
