Recycled arc mantle recovered from the Mid-Atlantic Ridge. [PDF]
Nat Commun, 2020 AbstractPlate tectonics and mantle dynamics necessitate mantle recycling throughout Earth’s history, yet direct geochemical evidence for mantle reprocessing remains elusive. Here we present evidence of recycled supra-subduction zone mantle wedge peridotite dredged from the Mid-Atlantic Ridge near 16°30′N.

Dense cold-water coral garden of Paragorgia johnsoni suggests the importance of the Mid-Atlantic Ridge for deep-sea biodiversity. [PDF]
Ecol Evol, 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.

Occurrence and characterization of tremolite asbestos from the Mid Atlantic Ridge. [PDF]
Sci Rep, 2021 Tremolite is one of the most common amphibole species and, in the fibrous form (i.e., characterized by crystals/particles consisting of fibres with length > 5 µm, width 3), one of the six asbestos minerals.

Detachment tectonics at Mid-Atlantic Ridge 26°N. [PDF]
Sci Rep, 2019 AbstractSpreading processes associated with slow-spreading ridges are a complex interplay of volcanic accretion and tectonic dismemberment of the oceanic crust, resulting in an irregular seafloor morphology made up of blocks created by episodes of intense volcanic activity or tectonic deformation. These blocks undergo highly variable evolution, such as

Cephalopods of the northern Mid-Atlantic Ridge [PDF]
Marine Biology Research, 2010 Abstract A two-leg cruise of R/V G. O. Sars in summer of 2004 along the Mid-Atlantic Ridge explored the diversity and distribution patterns of pelagic and non-hydrothermal bottom communities in the vicinity of the northern Mid-Atlantic Ridge. In total, 1295 cephalopods were caught, representing 56 species.

Microbial iron mats at the Mid-Atlantic Ridge and evidence that Zetaproteobacteria may be restricted to iron-oxidizing marine systems. [PDF]
PLoS One, 2015 Chemolithoautotrophic iron-oxidizing bacteria play an essential role in the global iron cycle. Thus far, the majority of marine iron-oxidizing bacteria have been identified as Zetaproteobacteria, a novel class within the phylum Proteobacteria.

Volcanic Geological Sites in UGGp European Geoparks: Special Issue [PDF]
Geoconservation Research, 2023 In this Special Issue, we present 11 of the 15 geoparks that show key aspects of the past and current volcanic development of Europe. The sites include currently active locations along the mid-Atlantic ridge, from the Canary Islands and the Azores in the

Feeding ecology of Coryphaenoides rupestris from the mid-Atlantic Ridge. [PDF]
PLoS ONE, 2010 The Macrourid fish roundnose grenadier, Coryphaenoides rupestris, is one of the most common benthopelagic fishes on the northern mid-Atlantic Ridge.

Nature Communications, 2022 Uniform magmatic crust formed at the Mid-Atlantic Ridge in the equatorial Atlantic Ocean reveals a two-dimensional mantle upwelling facilitated by the large transform faults and the high concentration of volatiles in the primitive melt in the mantle.
