Untangling sedimentation processes in a deep fjord lake in Labrador: A high‐resolution archive of past environment dynamics at Grand Lake

The Depositional Record, Volume 11, Issue 5, Page 1259-1284, November 2025.
Sedimentological and geochemical characteristics are used to reconstruct sedimentation dynamics and erosional processes. Several rapidly deposited layers are characterised over changing depositional environments during the Late Holocene, from a phase when the lake was connected to the sea to a more stable state conducive to varve formation.

Co‐Precipitation of Ni‐Rich Me(OH)2 Precursors for High Performance LiNixMnyCo1‐x‐yO2 Cathodes: A Review

ENERGY &ENVIRONMENTAL MATERIALS, Volume 8, Issue 6, November 2025.
This review addresses the nucleation mechanism and the thermodynamic and kinetic reaction processes of co‐precipitation. The comprehensive effects of key parameters on precursor physicochemical properties are also systematically interpreted. Notably, precursor characterization and physicochemical properties, including impurity levels and tolerance ...

Stad Slide: Preconditioning and failure of one of the world's largest megaslides

Journal of Quaternary Science, Volume 40, Issue 8, Page 1392-1406, November 2025.
ABSTRACT Submarine landslides can generate tsunamis and pose risks to underwater infrastructure, but a lack of direct observations of such slides hinders our understanding of their development and hazard potential. Studying the morphology of past slides can offer insights into their preconditioning and failure.

Misplaced fears? What the evidence reveals of the ecological effects of tidal power generation

Ecological Solutions and Evidence, Volume 6, Issue 4, October–December 2025.
Marine energy (tidal range and stream/flow) is a dependable and clean power source that stands out as a compelling alternative to fossil fuels. Despite widespread concerns surrounding the ecological effects of tidal energy infrastructure, we find few of these are substantiated by evidence or long‐term monitoring of existing tidal power projects.

Estimates of the Breaking Strength Parameter for Individual Oceanic Whitecaps

Geophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract The purpose of this study is to present the first estimates of the breaking strength parameter, b $b$, for individual oceanic whitecaps. This is achieved by combining the estimates of the dissipation rate per unit breaking crest length for these whitecaps reported in Callaghan et al.
