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
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.

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
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.
