INTRODUCTION. With an increasing international focus on the opportunities and costs of deep seabed polymetallic nodule mining (), a pressing matter to be resolved is the scale of the benthic sediment plume (hereinafter referred to as "sediment plume" or "plume") that would be generated by these activities ().Proposed operations will use a collector vehicle …

A: Yes. The deep ocean provides critical benefits to humanity—but unprecedented changes are already happening due to human-caused stressors such as climate change, habitat destruction, and overfishing. And the exploitation of the deep ocean could grow even worse if seabed mining moves forward. If we continue to proceed on …

The study found that noise from a single seabed mining operation in the CCZ would likely reverberate throughout the water column for up to 500 kilometers (310 miles). If each of the 17 contractors vying to mine in the CCZ were to operate simultaneously, an estimated 5.5 million square kilometers (2.1 million square miles) of ocean would have ...

Mining activities in the deep seabed could now be authorised by the International Seabed Authority (ISA) as early as mid-2023. In June 2021, the Government of Nauru notified the ISA of their intention to start deep-sea mining, triggering a rush to finalise the ISA regulations despite the existing knowledge gaps and lack of safeguards.

Deep-sea mining: fact sheet 6 Deep-sea mining: who stands to benefit? It is vital that before mining of the international seabed is given the green light, a fundamental question is considered: could it be that we – humankind – stand to lose far more than we could gain if the member nations of the ISA permit deep-seabed mining? UNCLOS and ...
