Building on the success of the two previous projects, MiningImpact 3 will further explore how deep-sea ecosystems function and respond to potential mining activities. The project focuses on two types of mineral deposits: polymetallic nodules (metal-rich ores scattered across the deep ocean floor) and seafloor massive sulphides (mineral deposits formed by hydrothermal vents at mid-ocean ridges).

Key Research Goals:
1) to assess the spatial and temporal variability of environmental variables, processes, and biodiversity on local and regional scales,
(2) to understand the regional scale genetic connectivity of deep-sea populations,
(3) to gain an understanding of the ecosystem functioning and structure that enables improved modelling capabilities,
(4) to study the effects of mining-induced ecotoxicity and pressures (e.g., substrate loss, blanketing) on benthic and pelagic communities.
The project will revisit sites of previous mining tests in the Clarion Clipperton Zone (Pacific Ocean) to study long-term effects and conduct new expeditions to unexplored areas, particularly focusing on inactive hydrothermal
vent sites along the Mid-Atlantic Ridge and Arctic Mid-Ocean Ridge.
Research results will support the development of tools for managing, regulating and governing deep-sea mining, thereby addressing the following objectives:
- developing indicators of ecosystem health and thresholds for serious harm,
- comparing the environmental impacts of deep-sea mining with land-based mining,
- advancing governance, monitoring and management tools (e.g. digital twin, adaptive management, social/ethical risk assessment),
- engaging with stakeholders to discuss ethical and societal implications of deep-sea mining.
All data and samples collected during the project will be made available following international standards for scientific data sharing, ensuring that this knowledge can benefit the wider scientific community and inform policy decisions.
Through this comprehensive approach, MiningImpact 3 continues its crucial role in providing independent scientific evidence to support informed decision-making about the future of deep-sea mining, while helping to protect these unique and valuable ecosystems.
