  • Three-dimensional management needs of deep-sea hydrothermal vent ecosystems

    Open AccessSabine Gollner, Aline Jaeckel et al.ARTICLEMarine Policy2025

    Deep-sea hydrothermal vents form small, unique, and fragile ecosystems that are widely recognized as sites in need of protection. Deep-seabed mining (DSM) is a future threat to hydrothermal ecosystem integrity. In most areas within, and in all areas beyond national jurisdiction, currently proposed protection measures from DSM are unlikely to be sufficient, as only the known active venting sites on the seafloor are intended to be protected from DS…

  • Illuminating deep-sea considerations and experimental approaches for mCDR proposals

    Open AccessNatalya D Gallo, Anna Metaxas et al.ARTICLEEnvironmental Research Letters2025

  • Assessing plume impacts caused by polymetallic nodule mining vehicles

    Open AccessP P E Weaver, Jacopo Aguzzi et al.ARTICLEMarine Policy2022

    Deep-sea mining may be just a few years away and yet society is struggling to assess the positive aspects, such as increasing the supply of metals for battery production to fuel the green revolution, versus the potentially large environmental impacts. Mining of polymetallic (manganese) nodules from the deep ocean is likely to be the first mineral resource targeted and will involve direct impacts to hundreds of km2 of seabed per mine per year. How…

  • Application of scientific criteria for identifying hydrothermal ecosystems in need of protection

    Open AccessSabine Gollner, Ana Colaço et al.ARTICLEMarine Policy2021

    Deep-sea hydrothermal vent fields are globally rare (abundant in numbers, but extremely small in area) and are rich in extraordinary life based on chemosynthesis rather than photosynthesis. Vent fields are also sources of polymetallic sulfides rich in copper and other metals. Mineral resources of the international seabed beyond national jurisdictions (referred to as the “Area”) are administered by the International Seabed Authority (ISA), which h…

  • Environmental considerations for impact and preservation reference zones for deep-sea polymetallic nodule mining

    Open AccessDaniel O B Jones, Jeff A Ardron et al.ARTICLEMarine Policy2020

    Development of guidance for environmental management of the deep-sea mining industry is important as contractors plan to move from exploration to exploitation activities. Two priorities for environmental management are monitoring and mitigating the impacts and effects of activities. International regulation of deep-sea mining activities stipulates the creation of two types of zones for local monitoring within a claim, impact reference zones (IRZ)…

  • Research is needed to inform environmental management of hydrothermally inactive and extinct polymetallic sulfide (PMS) deposits

    Open AccessCindy Lee Van Dover, Ana Colaço et al.ARTICLEMarine Policy2020

    Polymetallic sulfide (PMS) deposits produced at hydrothermal vents in the deep sea are of potential interest to miners. Hydrothermally active sulfide ecosystems are valued for the extraordinary chemosynthetic communities that they support. Many countries, including Canada, Portugal, and the United States, protect vent ecosystems in their Exclusive Economic Zones. When hydrothermal activity ceases temporarily (dormancy) or permanently (extinction)…
