Environmental Impacts and Risks of Deep-Sea Mining
Aug 2018 - Feb 2022
The second project phase MiningImpact follows up on the results of the JPI Oceans pilot action on "Ecological Aspects of Deep-Sea Mining" which ended in late December 2017 (see results here). While the initial MiningImpact phase investigated experimental and rather small-scale disturbances of the seafloor over decadal timescales, the second part will study and monitor in real time the environmental impact of an industrial trial to mine manganese nodules on the seafloor which will be conducted simultaneously and independently by the Belgian contractor DEME-GSR in the Belgian an German licence areas in the Clarion-Clipperton-Zone.
The project will further study regional connectivity of species in the deep-sea and their resilience to impacts, and the integrated effects on ecosystem functions, such as the benthic food-web and biogeochemical processes.
In this context, key objectives of the project are:
- To develop and test monitoring concepts and strategies for deep-sea mining operations
- To develop standardization procedures for monitoring and definitions for indicators of a good environmental status
- To investigate potential mitigation measures, such as spatial management plans of mining operations and means to facilitate ecosystem recovery
- To develop sound methodologies to assess the environmental risks and estimate benefits, costs and risks
- To explore how uncertainties in the knowledge of impacts can be implemented into appropriate regulatory frameworks
The Miningimpact 2018-2022 project is conducted independently of DEME-GSR activities. DEME-GSR is responsible for obtaining all necessary permissions for its operations and does not receive any funding from the MiningImpact project.
The respective environmental impacts assessments by BGR and DEME-GSR are online on the International Seabed Authority's website: https://www.isa.org.jm/environmental-impact-assessments
