Behavior and Ecology of Silky Sharks Around the Chagos Archipelago and Evidence of Indian Ocean Wide Movement

Frontiers in Marine Science, 2020
Silky sharks (Carcharhinus falciformis) represent a major component of global shark catch, both directly and as bycatch, and populations are declining as a result.

Insights Into Microscale Biomineralization in Deep‐Sea Callogorgia Coral via Halogen Banding

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract Halogen incorporation into coral carbonate skeletons serves as a valuable proxy for reconstructing paleoenvironments. However, the underlying mechanisms remain poorly understood. This study employed femtosecond laser ablation‐inductively coupled plasma time‐of‐flight mass spectrometry (fs‐LA‐ICP‐TOFMS) to perform multi‐elemental (I, Br, P, Ca,

Characterizing Incoming Cocos Plate Structure Outboard of the Guerrero Gap and Adjacent Segments Offshore Mexico: Implications for Along‐Strike Variations in Megathrust Slip Behavior

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract Megathrust slip behavior in subduction zones can vary along‐strike, yet the mechanisms driving this variability remain uncertain. The Middle America trench offshore Mexico provides an ideal setting to investigate the structural controls on megathrust slip behavior.

Examining Controls on Fluid Overpressure in Buried Basement Highs of Oceanic Crust: Implications for Permeability of the Astoria Fan

Geochemistry, Geophysics, Geosystems
Vigorous hydrothermal circulation in the basement aquifer of the oceanic crust homogenizes temperatures within the aquifer and generates fluid overpressures at the tops of buried basement highs.

Characterizing the Forearc Basement and Subducting Structures of the Northern Ecuadorian Margin

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract We present 2D P‐wave velocity (Vp) models from the northern Ecuadorian subduction zone, north of the Carnegie Ridge. Data were collected during the HIPER2 3D wide‐angle seismic experiment, both onshore and offshore. Key seismic profiles were manually picked to determine P‐wave first‐arrival times, which were used for a traveltime tomographic ...

Heat flows and chemical composition of volcanic samples from Henry Seamount, Meteor cruise M146

, 2020
Our knowledge of venting at intraplate seamounts is limited. Almost nothing is known about past hydrothermal activity at seamounts, because indicators are soon blanketed by sediment.

Halos of Enhanced Sediment Alteration Above Buried Seamounts Approaching the Cascadia Subduction Zone

Geochemistry, Geophysics, Geosystems
Sediment thermal history controls the progress of diagenetic reactions that can alter the mechanical behavior of material entering a subduction zone that then: accretes to the margin, hosts the plate boundary interface, or is carried deeper within the ...

The complete mitochondrial genome of a deep sea ophiuroid of the genus Amphiura (Ophiuroidea: Amphiuridae)

Mitochondrial DNA. Part B. Resources, 2019
Amphiura is a widely distributed genus of Ophiuroidea from various environment, play an important role in evolution. Here, we reported a complete mitochondrial genome of Amphiura sp. which was collected from a deep sea seamount in the West Pacific.

Testing the Seismic Detectability of Magmatic Underplating Beneath the Hawaiian Ridge: A Synthetic Wavefield Approach

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Magmatic underplating beneath the Hawaiian Ridge has been inferred from early active‐source and teleseismic studies, whereas more recent active‐source seismic imaging and reprocessed legacy data have not identified a distinct underplated layer.
