Mo Isotopic Records Imply Persistent Ocean Oxygenation in the Deep Southwest Pacific During the Early Cenozoic Warming Period

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract During the early Cenozoic greenhouse period, counterintuitive contractions in tropical Pacific oxygen‐deficient zones have been linked to enhanced deep‐ocean ventilation, yet direct geological evidence remains limited. Here we present molybdenum (Mo) isotopic records from International Ocean Discovery Program Site U1509.

Channelization Versus Retardation During Trace Element Segregation in Compaction‐Driven Fluid Flow

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract The migration of fluids, such as aqueous fluids and melts, is often channelized and crucial for trace element transport. However, trace elements typically migrate slower than the fluid due to partitioning between solid and fluid phases, known as retardation.

Deformation of the Upper Oceanic Crust in the Outer Rise of the Sumatra Subduction Zone: Insights From P‐ and Doubly Converted S‐Wave Arrivals on Downward Continued Streamer Data

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract The structure and properties of mature upper oceanic plates may evolve through mechanisms such as magmatism, hydrothermal circulation, and faulting. However, high‐resolution constraints, especially those involving both P‐ and S‐waves, remain scarce, limiting our ability to detect these processes and assess their impacts on crustal properties ...

Sediment Characteristics in Stonewort Chara tomentosa Assemblages

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
The study investigated sediment characteristics associated with Chara tomentosa. The results show that sediment grain size and the concentration of the dissolved phosphate in the porewater differ in the seafloor areas characterised by C. tomentosa from adjacent areas at similar depth, but without charophytes.
