In the late 1980s, as the first wave of deep-sea mining exploration approached a decade of hibernation, researchers launched an ambitious experiment to understand the long-term environmental impact of harvesting polymetallic nodules from the abyssal plain. The Disturbance and recolonization experiment in a manganese nodule area of the deep South Pacific (DISCOL) remains the most […]

Maria Bolevich for DSM Observer The coronavirus pandemic is changing the world in dramatic and subtle ways, exacting a toll measured both in lost lives and economic uncertainty. Deep-sea mining has been in development for over 50 years and now, at the moment in which negotiations were poised to transition the industry from exploration to […]

Maria Bolevich for DSM Observer Dr. Malcolm R. Clark is a principal scientist at the National Institute of Water and Atmospheric Research in Wellington, New Zealand, he began his career in the 1980s. “My career started with fisheries stock assessment, and evolved through studying the diversity of deep-sea life and how it is impacted by […]

2019 was a landmark year for deep-sea mining. As the 25th anniversary of the International Seabed Authority, the pressure was on to advance the industry from promise to production. The surge in cobalt prices in 2018 led to renewed interest in new sources of this essential but often troubled resource but also yielded a precipitous […]

Last week saw the conclusion of the 25th Session of the International Seabed Authority. Though much progress was made, significant work still lies ahead to meet to self-imposed 2020 deadline for implementing the draft exploitation regulations. As always, the Earth Negotiations Bulletin has provided a comprehensive summary of the overall meeting as well as day-to-day […]

In 2001, on an expedition to hydrothermal vent fields in the Indian Ocean, researchers made a bizarre discovery. Clustered in small aggregations around the base of a black smoker was an unusual snail, seemingly clad in a suit of armor. Rather than a single, hard, calcareous structure, the snail’s operculum was covered in a series […]

In 1989, the largest attempt to model the impacts of a deep-sea mining operation was conducted across 1100 hectares of seafloor in the Peru Basin. The Disturbance and Recolonization Experiment (DISCOL) simulated polymetallic nodule extraction by dragging an 8-meter plough-harrow across a nodule field, creating 78 troughs that mimicked one likely consequence of dragging a […]

1. Outcomes from the LTC. In the next few weeks, the Legal and Technical Committee will release their draft regulations for mining polymetallic nodules in the Area. There will be an opportunity for comments and input from the deep-sea mining community prior to the LTC, Council, and General Assembly meetings this summer. 2. Patania II […]

2018 was a banner year for studies highlighting the importance of hydrothermal vents not just to the highly specialized communities that thrive around seafloor massive sulphides, but also to the surrounding benthic community. Vents provide nursery grounds for octopuses and deep-sea skates, but they also provide food for deep-sea and shallow water animals. At shallow-water […]

Social media offers a snapshot of the human networks surrounding a particular issue. It makes public the conversations and relationships that once were hidden behind closed doors and over private phone lines. And, when the conversation is well-organized, it assumes keywords that make it searchable as well. What you see below is the snapshot of […]
