The impacts of deep seabed mining on people have not been sufficiently researched or addressed. Using a legitimacy framework, we discuss the social-equity dimensions this emerging industry in ocean commons.
The establishment of thresholds is integral to environmental management. This paper introduces the use in context deep-seabed mining, a nascent industry for which an exploitation regime regulations, standards and guidelines still process being developed, roles values have yet be finalised. There are several options integrating into International Seabed Authority's regulatory regime, from stipulated regulations part mining contract, each option having its own advantages disadvantages. Here we...
Oceans provide critical ecosystem services, but are subject to a growing number of external pressures, including overfishing, pollution, habitat destruction, and climate change. Current models typically treat stressors on species ecosystems independently, though in reality, often interact ways that not well understood. Here, we use network interaction model (OSIRIS) explicitly study stressor interactions the Chukchi Sea (Arctic Ocean) due its extensive climate-driven loss sea ice accelerated...
Abstract The Falkland Shelf is a highly productive ecosystem in the Southwest Atlantic Ocean. It characterized by upwelling oceanographic dynamics and displays wasp-waist structure, with few intermediate trophic-level species many top predators that migrate on shelf for feeding. One of these resident species, Patagonian longfin-squid Doryteuthis gahi, abundant plays an important role ecosystem. We used two methods to estimate trophic structure food web, focusing niche D. gahi its impacts...
Interest in the mining of polymetallic nodules, sulfide deposits, and ferromanganese crusts deep sea is growing. While impacts deep-sea on benthic systems are somewhat understood, there little information available pelagic via, for example, discharge plume. The these suspended sediments communities can have consequences fishing industry if their target species directly or indirectly impacted. Here, we quantify how tuna fisheries high seas spatially intersect with areas which exploration...
Abstract In ocean areas beyond national jurisdiction, various legal regimes and governance structures result in diffused responsibility create challenges for management. Here we show those are set to expand with climate change driving increasing overlap between eastern Pacific tuna fisheries the emerging industry of deep-sea mining. Climate models suggest that distributions will shift coming decades. Within Clarion-Clipperton Zone Ocean, a region containing 1.1 million km 2 mining...
Increased suspended sediment concentrations (SSC) are a major stressor across aquatic habitats. Here, the literature was synthesized to show that animal responses increases in relative SSC (test concentration/natural background concentration) were similar type and negative different shallow-water (marine, estuarine, freshwater) Further, sensitivities habitats based on occur starting at low all despite differences natural SSC. Based upon these similarities sensitivities, deep-sea sensitivity...
Introduction A defining aspect of the Intergovernmental Panel on Climate Change (IPCC) assessment reports (AR) is a formal uncertainty language framework that emphasizes higher certainty issues across reports, especially in executive summaries and short for policymakers. As result, potentially significant risks involving understudied components climate system are shielded from view. Methods Here we seek to address this latest, sixth report (AR6) one such component—the deep ocean—by...
The Clarion-Clipperton Zone (CCZ) is a 4 million km 2 area in the eastern Central Pacific Ocean exhibiting large variability environmental parameters, particularly oxygen and primary production, that being targeted for deep-sea polymetallic nodule mining. This remote region’s pelagic biology very poorly sampled, including micronekton zooplankton provide essential ecosystem services such as carbon flux support commercial fisheries. We built baseline of deep scattering layer (DSL) depths...
The deep ocean comprises complex ecosystems made up of numerous community and habitat types that provide multiple services benefit humans. As the industrialization sea proceeds, a standardized robust set methods metrics need to be developed monitor baseline conditions any anthropogenic climate change-related impacts on biodiversity, ecosystem function, services. Here, we review what have learned from studies involving offshore-energy industries, including state-of-the-art technologies...
Abstract A key obstacle to conservation success is the tendency of professionals tackle each challenge individually rather than collectively and in context. We sought prioritize barriers previously described literature. undertook an online survey 154 practitioners from over 70 countries ascertain most important they faced. used statistical analyses identify impediments examine whether these were affected by organizational attributes. Twenty‐one identified. The importance ascribed those was...
Abstract Direct interactions between marine mammals and commercial fisheries are a worldwide conservation challenge. Observer programmes remain the most effective reliable method for collecting data on these interactions. In Falkland Islands—home to globally significant seal populations squid fisheries, seal-fishery have escalated in recent years, prompting management concerns. Complete observer coverage within fishery presents valuable opportunity investigate nature, extent, drivers of...
The marine environment is increasingly threatened by multiple anthropogenic stressors, and the future of ecosystem services at stake. To ensure that biodiverse ecosystems related are preserved, management should be robust to uncertainty in combined effects stressors. Furthermore, it important plural values diverse human-nature relationships adequately represented environmental valuation. This study couples modelling with a novel valuation framework estimate changes temporal dynamics service...
While much has been learnt about the impacts of specific stressors on individual marine organisms, considerable debate exists over nature and impact multiple simultaneous both species ecosystems. We describe a modelling tool (OSIRIS) for integrating effects stressors. The model is relatively computationally light, demonstrated using coarse-grained, non-spatial simplified representation temperate ecosystem. This version capable reproducing wide range dynamic responses.Results indicate degree...
Abstract Patterns in body size are important to study as the of an organism correlates with many biological traits organism. Changes distribution a community can be indicative environmental change and/or anthropogenic impacts. What structures is, however, still poorly understood, factors proposed and shown influence size, including energy, which is likely major driver. The deep sea good test bed explore relationship between availability energy it energy‐poor system, strong responses changes...
