Slab‐Mantle Interaction During Subduction Initiation: Constraints From Trace Element and Sr‐Nd‐Pb Isotope Systematics of Boninite and Other Magmas and Metamorphic Sole in the Oman Ophiolite

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The Late Cretaceous Oman ophiolite includes a series of volcanic rocks generated during the transition from spreading ridge to protoarc associated with subduction initiation. We analyzed major and trace elements and Sr, Nd, and Pb isotope compositions of lavas and dikes of the protoarc stage, especially boninites. We also analyzed amphibolites

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

open access: yesGeochemistry, 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 ...

Louisville Seamount Chain: Petrogenetic processes and geochemical evolution of the mantle source

open access: yesGeochemistry, Geophysics, Geosystems, 2014
The Louisville Seamount Chain is a ∼4300 km long chain of submarine volcanoes in the southwestern Pacific that spans an age range comparable to that of the Hawaiian‐Emperor chain and is commonly thought to represent a hot spot track.

Characterization and Phylogenetic Analysis of a Novel Uncultivated Magnetotactic Coccus Harbouring Multi‐Chain Magnetosomes

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 1, February 2026.
A novel marine magnetotactic coccus, strain HHB‐1, was isolated from intertidal sediments in Houhai Bay, China. HHB‐1 cells are large coccoid–ovoid bacteria that contain multiple chains of prismatic magnetite magnetosomes and conspicuous Ca/Mg‐rich polyphosphate granules.

Deep-sea coral distribution on seamounts, oceanic islands, and continental slopes in the Northeast Atlantic [PDF]

open access: yes, 2007
A database of deep-water (\u3e 200 m) antipatharians, scleractinians, and gorgonians has been assembled for the NE Atlantic to determine what their distribution and diversity was before coral habitats became heavily impacted by bottom fishing gear ...

Achieving Full Representativity of Seafloor Biodiversity With Minimal Expansion: Exploring a Strategy for New Zealand Marine Conservation

open access: yesDiversity and Distributions, Volume 32, Issue 2, February 2026.
ABSTRACT Aim A key element of the Global Biodiversity Framework Target 3 is ‘representativity’, which refers to the inclusion of the full range of existing ecosystems, ecological processes and regions within protected areas, with the aim of ensuring that the full spectrum of biodiversity is protected.

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

open access: yesMitochondrial 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.

Facies analysis provides new insights into event bed deposition in a hadal trench environment

open access: yesSedimentology, Volume 73, Issue 2, Page 441-477, February 2026.
ABSTRACT Hadal trenches preserve exceptional sedimentary archives of past geological events, yet their depositional processes remain poorly constrained. The Japan Trench captures complex earthquake‐triggered event beds that record repeated sediment‐gravity flows that deliver terrigenous and biogenic material into the trench, informing palaeoseismic ...
