The Transformation of Trace Metal Distributions Across the Mackenzie Shelf and Through the Northwest Passage

Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.
Abstract Understanding the distributions of trace elements, like iron (Fe), manganese (Mn), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), cadmium (Cd), lead (Pb), barium (Ba), and vanadium (V) in the Arctic Ocean is motivated in part because they can modulate key biogeochemical rate processes as micronutrients and/or toxins for primary producers ...

Quantifying Groundwater–Surface Water Exchange on a River Island: A Comparative Analysis of Direct and Indirect Methods

Water Resources Research, Volume 62, Issue 10, October 2026.
Abstract Groundwater–surface water exchange is a key hydrological process that governs river water quality and aquatic ecosystems. However, the quantification of such exchange remains uncertain, especially within river island aquifers where exchange processes are highly heterogeneous.

Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

Boreas, Volume 55, Issue 4, Page 964-992, October 2026.
Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...

Typhoon‐Driven Near‐Surface Groundwater Dynamics Revealed by Ambient Noise in the Mountain Watershed

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Near‐surface groundwater dynamics (NSGD) regulate water residence time and downstream water resources in mountain watersheds, yet whether a single extreme rainfall event can reorganize near‐surface storage remains unclear. Here, we examine typhoon‐driven NSGD using ambient seismic noise from four stations, together with hydrological and ...

Optimizing Stratification in Binary Colloidal Supraparticles

Advanced Science, Volume 13, Issue 52, 18 September 2026.
Supraparticles from binary particle populations show stratification when dried at high Péclet numbers. In spray‐dried systems at high initial particle concentration and fast drying conditions optimal combinations of particle size ratios and volume fractions that produce maximal stratification are found both in experiment and simulation, contrasting the

A CE/SE Scheme for Flows in Porous Media and Its Applications [PDF]

, 2009
In this paper, a new computational scheme for solving flows in porous media was proposed. The scheme was based on an improved CE/SE method (the space-time Conservation Element and Solution Element method).

Surface hydration‐induced damage in tight oil‐bearing sandy conglomerate reservoirs

Deep Underground Science and Engineering, Volume 5, Issue 3, Page 809-828, September 2026.
A series of techniques such as X‐ray diffraction, scanning electron microscopy, energy‐dispersive spectroscopy, conductivity tests, and infrared thermal imaging were used. The key findings are the identification of a two‐stage surface hydration process and the elucidation of the effects of various minerals and elements on the hydration process ...
