Background: 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 delimitation, including imagery of voucher specimens, Darwin Core (DwC) data and links to vouchered specimen material and new GenBank sequence records. This paper includes genetic and imagery data for 129 species of annelids from 339 records and is restricted to material that is, in general, in too poor a condition to describe formally at this time, but likely contains many species new to science. We make these data available both to aid future taxonomic studies in the CCZ that will be able to link back to these genetic data and specimens and to better underpin ongoing ecological studies of potential deep-sea mining impacts using the principles of FAIR (Findable, Accessible, Interoperable, Reusuable) data and specimens that will be available for all.
New Information: We include genetic, imagery and all associated metadata in Darwin Core format for 129 species of annelids from the Clarion-Clipperton Zone, eastern abyssal Pacific, with 339 records.

Polymetallic nodules' (PMNs) deep-sea mining poses risks to marine ecosystems, yet its effects on surface picophytoplankton remain unclear. This study assessed metal release from PMNs and its impact on picophytoplankton in the Clarion-Clipperton zone through laboratory and field incubation experiments. PMNs particles, particularly finer ones, released chromium, cobalt, nickel, and copper more rapidly under light exposure, high salinity, and algal secretion.

In an era where human activities increasingly impact the deep sea and, with future ventures such as deep-sea mining on the horizon, describing deep-sea biodiversity is vital for conservation, sustainable resource management, understanding global ecological processes, and informing policy decisions. Polymetallic nodule fields, in particular, have been proven to be reservoirs of previously undiscovered biodiversity. As part of ongoing efforts to unveil this dark diversity, two new species of Caymanostella -Caymanostella persephone nov.

Deep-sea mining activities in the Clarion-Clipperton Zone (CCZ), Pacific Ocean, are expected to generate continuous noise pollution across multiple depth zones, with potential impacts on biodiversity. Impact studies have primarily focused on sediment plumes and habitat destruction, leaving consequences of industrial-scale deep-sea mining noise largely unexplored. Many marine taxa, including invertebrates, fish, and mammals, rely on sound for communication, navigation, and predator avoidance.

This study investigates MPs in sediments and polymetallic nodules collected from the Clarion Clipperton Zone (CCZ) in the Pacific Ocean, using samples collected during a deep-sea mining exploration. MPs were detected in over half of the sediment samples and a third of the nodule samples, with an abundance ranging from 0 to 480 items/kg dry weight (d.w.

The abyssal plains of the Clarion-Clipperton Zone (CCZ) are famous for their fields of polymetallic nodules, which are inhabited by benthic invertebrates. Ten specimens from the Interoceanmetal Joint Organisation (IOM) licence area in the CCZ were collected in 2014 and submitted to a short-read genome skimming sequencing. In total, mitochondrial genomes and nuclear ribosomal genes were retrieved for nine different organisms belonging to Ophiuroidea, Holothuroidea, Polychaeta, Bryozoa, Porifera, and Brachiopoda (assigned to these phyla immediately upon retrieval from the seafloor).
