TRIDENT aims to contribute to a sustainable exploitation of seabed mineral resources, by developing a reliable, transparent and cost-effective system for prediction and continuous monitoring of the environmental impact of exploration and exploitation activities in the deep sea. This system will develop and integrate technology and novel solutions to operate autonomously in remote areas under extreme conditions and provide real-time data to permitting and supervising authorities. The effective monitoring and inspection system to be developed will comply with international and national legal frameworks.

TRIDENT will identify all relevant parameters: physical, chemical, geological, and biological to be measured at the sea surface, mid-water and seabed. The project will also identify gaps in existing data sets and develop solutions to address them. These are essential steps to develop statistically robust environmental baselines, establish reliable indicators of good environmental status and define thresholds for significant impact, enabling the standardization of tools and methods. The project consortium will subsequently develop and test an integrated system of static and mobile observatory platforms equipped with the latest automatic sensors and samplers to measure environmental parameters on mining and reference areas at representative spatial and temporal scales. To support quick actions for preventing serious harm to the environment, the system will implement high-capacity data handling pipelines able to collect, transmit, process and display monitoring data in near real-time. Finally, we will provide technological and systemic solutions for forecasting potential environmental impacts by using the developed monitoring and mitigation methods.

Our role

Timelex is the legal partner in the TRIDENT project. Our involvement mainly relates to (environmental) data governance. We examine the international and European legislative framework regarding pilot research activities in the Deep Sea environment while also assessing its overall impact on project activities. We assist project partners with questions they may have when going to the sea with their vessel and what permits they need for research missions at sea, along with those needed when the use of seabed is to be considered in terms of applicable law.
