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 […]

Of all the world’s oceans, the Indian Ocean is among the least explored. This is especially true in the deep Indian Ocean, which is rarely visited, despite being host to numerous ecosystems hosting new and novel species not seen anywhere else in the world. At the recent ISA Council meeting, one delegate even noted in […]

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 […]

The deep sea has a PR problem. Most people have little to no conception of what deep ocean ecosystems look like, what lives there, or how human well-being may depend on them. Deep-sea ecosystems provide many indirect services that benefit humanity, yet they are poorly quantified and infrequently discussed. A new paper by graduate student […]

Deep-sea mining, as both an industry and community of practice, is highly engaged in the scientific process. From plume flow models to environmental baselines to new engineering advancements, much of the core discussions happening in deep sea mining happens within the scientific literature. This is incredibly valuable when it comes to fostering partnerships and collaborations […]

Taking a systems approach to deep sea mining shows engaging the public is key to the sustainable development and governance of the industry.

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 […]

Rachel Pendergrass | 15 November 2018 Giant gyers of floating plastic have long been at the forefront of the public conversation around ocean pollution, but there has been a dearth of research on the deeper issue of plastic that reaches below the surface. Since the onset of mainstream plastic production begin in the 1940s and […]
