Dear Professor Chung,
Thank you for your question.
According to our investigation, we have found many papers arguing that deep-sea mining would bring serious disturbance to the environment around the seabed. And it is investigated that impact of improper mining method remains for decades after the mining activity. We believe that studying environment-friendly collection method would dispel environmental groups’ doubt and worry on deep-sea mining. To search for a better nodules extraction method which minimizes the disturbance, we study the mechanical and hydraulic collection.
