Abstract
One of the major concerns for deep seabed mining is not only its environmental impact from the disturbance of benthic communities due to the mining activity but the disposal of mine tailings back to the ocean. Yet a significant amount of waste materials would be produced from the on-deck processing on the mining platform, all the materials that produced on the mining platform are to be shipped to the land except where such mining discharge is permitted under the guidelines and regulations by IMO and ISA (ISA, 2018). Still, ecotoxicology data for the deep seabed minerals from case studies in deep-sea tailings disposal (DSTD) and submarine tailings disposal (STD) sites are lacking and all other related aspects are also largely unknown. This year, the Republic of Korea has started a research project for the more comprehensive understanding of chemical and physical properties of mine tailings from the on-deck processing and the possible environmental impacts on the marine organisms after its disposal. Based on the scientific data collected from this project, Korea would be able to make recommendations for the methods and technical standards for the deep seabed mining discharges. The subjects of this project are threefold: to understand the physical/chemical properties of the tailings, to model the dispersion of particulates after the disposal, and to assess its impact on the marine ecology.ste materials would be produced from the on-deck processing on the mining platform, all the materials that produced on the mining platform are to be shipped to the land except where such mining discharge is permitted under the guidelines and regulations by IMO and ISA (ISA, 2018).
