The deep sea encompasses the largest ecosystems on Earth. Although poorly known, seafloor provide services that are vitally important to entire ocean and biosphere. Rising atmospheric greenhouse gases bringing about significant changes in environmental properties of realm terms water column oxygenation, temperature, pH food supply, with concomitant impacts deep-sea ecosystems. Projections suggest abyssal (3000–6000 m) temperatures could increase by 1°C over next 84 years, while habitats...
Although initially viewed as oases within a barren deep ocean, hydrothermal vent and methane seep communities are now recognized to interact with surrounding ecosystems on the sea floor in water column, affect global geochemical cycles. The importance of understanding these interactions is growing potential rises for disturbance from oil gas extraction, seabed mining bottom trawling. Here we synthesize current knowledge nature, extent time space scales background systems. We document an...
Abstract Aim Globally, species distribution patterns in the deep sea are poorly resolved, with spatial coverage being sparse for most taxa and true absence data missing. Increasing human impacts on deep‐sea ecosystems mean that reaching a better understanding of such is becoming more urgent. Cold‐water stony corals (Order Scleractinia) form structurally complex habitats (dense thickets or reefs) can support diversity other associated fauna. Despite their widely accepted ecological...
Mora and colleagues show that ongoing greenhouse gas emissions are likely to have a considerable effect on several biogeochemical properties of the world's oceans, with potentially serious consequences for biodiversity human welfare.
Abstract Aim Three‐quarters of Octocorallia species are found in deep waters. These cold‐water octocoral colonies can form a major constituent structurally complex habitats. The global distribution and the habitat requirements deep‐sea octocorals poorly understood given expense difficulties sampling at depth. Habitat suitability models useful tools to extrapolate distributions provide an understanding ecological requirements. Here, we present maps for seven suborders Octocorallia:...
Abstract Cold‐water stony corals create habitat for a diverse range of deep‐water species but are thought to be threatened by ocean acidification due oceanic uptake anthropogenic CO 2 . Knowledge the severity this threat is hampered our limited understanding distribution and requirements these corals. Here we estimate global organisms using database cold‐water coral records modelling approach. We parameterised models present‐day environmental data, then replaced data with future projections...
Abstract Aim The benthic fauna of seamounts typically includes organisms that are slow‐growing, long‐lived and sensitive to mechanical disturbance, making susceptible anthropogenic impacts. Such impacts may arise from mining cobalt‐rich crusts, envisaged for in the central North Pacific; this scenario requires environmental guidelines operations on be developed. Here, we provide biological information essential effective conservation planning deep‐sea features targeted such mining. Location...
Cold seep communities with distinctive chemoautotrophic fauna occur where hydrocarbon-rich fluids escape from the seabed. We describe community composition, population densities, spatial extent, and within-region variability of epifaunal at methane-rich cold sites on Hikurangi Margin, New Zealand. Using data towed camera transects, we match observations to information about probable life-history characteristics principal develop a hypothetical succession sequence for communities, onset fluid...
A new species of cirolanid isopod, Bathynomus maxeyorum sp. nov., from The Bahamas, Western Atlantic, is described. This represents the fourth to be described tropical and sub-tropical Atlantic. nov. characterized by 7 broad short pleotelsonic spines, with setation running along ~80% posterior margin pleotelson. Genetic analysis indicates a ~14% sequence divergence sympatric giganteus.
Growing human activity in areas beyond national jurisdiction (ABNJ) is driving increasing impacts on the biodiversity of this vast area ocean. As a result, United Nations General Assembly committed to convening series intergovernmental conferences (IGCs) develop an international legally-binding instrument (ILBI) for conservation and sustainable use marine biological diversity ABNJ [the (BBNJ) agreement] under Convention Law Sea. The BBNJ agreement includes consideration genetic resources...
The Hawaiian gold coral has a history of exploitation from the deep slopes and seamounts Islands as one precious corals commercialised in jewellery industry. Due to its peculiar characteristic building scleroproteic skeleton, this zoanthid been referred Gerardia sp. (a junior synonym Savalia Nardo, 1844) but never formally described or examined by taxonomists despite commercial interest. While collection is now regulated, globally habitats are increasingly threatened variety anthropogenic...

We report signs of recovery on protected seamounts 30- to 40-year time scales.
Recent studies have countered the paradigm of seamount isolation, confounding conservation efforts at a critical time. Efforts to study deep-sea corals, one dominant taxa on seamounts, understand connectivity, are hampered by lack taxonomic keys. A prerequisite for connectivity is species overlap. Attempts better overlap using DNA barcoding methods suggest coral widely distributed seamounts and nearby features. However, no baseline has been established variation in these genetic markers...

We use full mitochondrial genomes to test the robustness of phylogeny Octocorallia, determine evolutionary pathway for five known gene rearrangements in octocorals, and suitability using higher taxonomic-level phylogenetic reconstructions. Our supports three major divisions within Octocorallia show that Paragorgiidae is paraphyletic, with Sibogagorgia forming a sister branch Coralliidae. Furthermore, cauliflora has what presumed be ancestral order but presence pair inverted repeat sequences...
Deep-sea scleractinian coral reefs are protected ecologically and biologically significant areas that support global fisheries. The absence of observations deep-sea in the Central Northeast Pacific, combined with shallow aragonite saturation horizon (ASH) high carbonate dissolution rates there, fueled hypothesis reef formation North Pacific was improbable. Despite this, we report discovery live on six seamounts Northwestern Hawaiian Islands Emperor Seamount Chain at depths 535-732 m state...
Discovery of chemosynthetic communities associated with whale bones led to the hypothesis that falls may serve as stepping-stones for faunal dispersal between disjunct hydrothermal vents and cold seeps on ocean floor (1). The initial observation was followed by a inventory revealed diverse assemblage microbes invertebrates, supported chemoautotrophic production, living in close proximity remains (2, 3). To date, conspicuous absence from vestimentiferan tubeworms (a predominant constituent...
