Dense cold‐water coral garden of Paragorgia johnsoni suggests the importance of the Mid‐Atlantic Ridge for deep‐sea biodiversity

open access: yesEcology and Evolution, 2021
Mid‐ocean ridges generate a myriad of physical oceanographic processes that favor the supply of food and nutrients to suspension‐ and filter‐feeding organisms, such as cold‐water corals and deep‐sea sponges.

A Highly Depleted and Subduction‐Modified Mantle Beneath the Slow‐Spreading Mohns Ridge

open access: yesGeochemistry, Geophysics, Geosystems, 2022
The Mohns Ridge is a very slow‐spreading ridge that, together with the Knipovich Ridge, marks the boundary between the North American and Eurasian plates in the Norwegian‐Greenland Sea.

Origin of Alkaline Basaltic Intrusive Rocks in an Exhumed Accretionary Complex: Implications for Past Petit‐Spot Volcanism in the Ocean

open access: yesGeochemistry, Geophysics, Geosystems, 2023
Accreted basaltic rocks are expected to provide information on intraplate volcanism in the oceans. Basaltic rocks, originating from mid‐ocean ridges, plateaus, and seamounts, have been reported from exhumed accretionary complexes. However, basaltic rocks

Persistent Magma‐Rich Waves Beneath Mid‐Ocean Ridges Explain Long Periodicity on Ocean Floor Fabric

open access: yesGeophysical Research Letters, 2022
The ocean floor makes up the majority of the Earth's surface and yet, its geomorphology is not fully understood. Recent debate has focused on whether sea level changes—driven by Milankovitch glacial cycles—generate the abyssal hill fabric of the ocean ...

Corals and Reef‐Dwelling Fish Regulate Carbon Storage and Cycling Processes in Coral Reef Ecosystems

open access: yesAdvanced Science, EarlyView.
Coral reefs are biodiversity hotspots, yet their role in carbon storage and cycling remains poorly understood. Using field surveys and modeling in the South China Sea, we reveal the overlooked potential of carbon storage in reef ecosystems and how reef fish, corals, and surface sediment jointly shape reef carbon reservoirs.

A new species of Lonchidiidae (Hybodontiformes) from the Late Jurassic of Brazil (Aliança Formation, Jatobá Basin)

open access: yesThe Anatomical Record, EarlyView.
Abstract The Aliança Formation (Jatobá Basin) represents lacustrine deposits formed in oxygenated waters that hosted a diverse fauna, including Hybodontiform sharks. Within this group, the Family Lonchidiidae comprises 11 valid genera, with Parvodus previously reported in Brazilian deposits from the Brejo Santo Formation (Araripe Basin, Late Jurassic ...

Multiphase Tectonic Process With Slab Dynamics in the Northern East China Sea Shelf Basin

open access: yesGeological Journal, EarlyView.
Megasequence 1 characterised by Palaeocene extension and differential subsidence driven by the rollback of the subducting Izanagi Plate. Megasequence 2 records a kinematic reorganisation of the East Asian margin, transition from a rifting to a compressional regime.

Complete mitochondrial genome sequence of the genus Austinograea (Malacostraca: Brachyura: Bythograeidae) and its phylogenetic analysis

open access: yesMitochondrial DNA. Part B. Resources, 2020
Austinograea species are restricted to hydrothermal vents and are typically considered to be omnivorous predators in vent communities. Here we present the complete mitochondrial genome of Austinograea sp. which was collected from Carlsberg Ridge, the mid-

The Energetic 2022 Seismic Unrest Related to Magma Intrusion at the North Mid‐Atlantic Ridge

open access: yesGeophysical Research Letters, 2023
A seismic swarm affected the 53.3°–54.3° Latitude North section of the Mid‐Atlantic Ridge from 26 September to 10 December 2022. We rely on regional, teleseismic and array data to relocate 61 hypocenters and derive 77 moment tensors.
