Research questions

Broad: What are the environmental effects of deep-sea mining? How do we mitigate these in the event of commercial deep-sea mining? How do we ensure companies adhere to mitigation measures?

What are the physical processes that govern the behaviour of sediment clouds and plumes produced near deep-sea mining sites?

How can we improve models of how these clouds pollute the water column, both physically and chemically via dissolution?

How can oceanographic and biogeochemical modelling techniques be employed to predict how these environmental stresses will spread in the oceans?

What scientific methods and techniques are viable for real-time monitoring of commercial deep-sea mining?

How do we ensure that companies adhere to self-verification measures and thresholds set by the International Seabed Authority?
