Checklist of newly-vouchered annelid taxa from the Clarion-Clipperton Zone, central Pacific Ocean, based on morphology and genetic delimitation [PDF]

Biodiversity Data Journal, 2023
We present a checklist of annelids from recent United Kingdom Seabed Resources (UKSR) expeditions (Abyssal Baseline - ABYSSLINE project) to the eastern abyssal Pacific Clarion-Clipperton Zone (CCZ) polymetallic nodule fields, based on DNA species ...

Relational or abyssal?

Political Geography, 2022
What I characterise (with David Chandler) as ‘abyssal work’ is (re)turning to the Caribbean in a significant way, as a powerful vortex; an explosive, highly generative, geo-ontological space which enables us to more sharply delineate the stakes of critique – on the one hand, opening out to how everything is co-constituted through traceable inter ...

Deep-sea scavenging amphipod assemblages from the submarine canyons of the Western Iberian Peninsula [PDF]

Biogeosciences, 2012
Submarine canyons have often been identified as hotspots of secondary production with the potential to house distinct faunal assemblages and idiosyncratic ecosystems. Within these deep-sea habitats, assemblages of scavenging fauna play a vital role in

Distribution of species in deep-sea biogeographic provinces and molecular phylogeny for the superfamily Neotanaoidea (Peracarida; Tanaidacea) indicate high levels of connectivity

Frontiers in Marine Science
Here we analyze available recorded occurrences for species of Neotanaoidea, a deep-sea peracarid superfamily, in the frame of biogeographic bathyal, abyssal, and hadal provinces.

An End-to-End DNA Taxonomy Methodology for Benthic Biodiversity Survey in the Clarion-Clipperton Zone, Central Pacific Abyss

Journal of Marine Science and Engineering, 2015
Recent years have seen increased survey and sampling expeditions to the Clarion-Clipperton Zone (CCZ), central Pacific Ocean abyss, driven by commercial interests from contractors in the potential extraction of polymetallic nodules in the region. Part of

Petrogenetic Implications for Ophiolite Ultramafic Bodies from Lokris and Beotia (Central Greece) Based on Chemistry of Their Cr-spinels

Geosciences, 2017
Cr-spinels from ultramafic rocks from Lokris (Megaplatanos and Tragana), and Beotia (Ypato and Alyki) ophiolitic occurrences were studied. These rocks comprise principally harzburgite with minor dunite. Small amounts of clinopyroxene-rich harzburgite and

Sea level anomalies affect the ocean circulation at abyssal depths

Scientific Reports, 2023
Abyssal channels are the key points controlling bottom circulation of the World Ocean. They provide meridional transport of the coldest Antarctic Bottom Water between deep-water basins influencing the meridional overturning circulation and the climate on

Abyssal Slope Currents [PDF]

Journal of Physical Oceanography
Abstract Realistic computational simulations in different oceanic basins reveal prevalent prograde mean flows (in the direction of topographic Rossby wave propagation along isobaths; aka topostrophy) on topographic slopes in the deep ocean, consistent with the barotropic theory of eddy-driven mean flows.

Biogeographic Insights Into the Late Miocene Diversification of the Giant Deep‐Ocean Amphipod Eurythenes

Ecology and Evolution
Mechanisms driving the spatial and temporal patterns of species distribution in the Earth's largest habitat, the deep ocean, remain largely enigmatic. The late Miocene to the Pliocene (~23–2.58 Ma) is a period that was marked by significant geological ...

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

Biological Reviews, EarlyView.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis
