 — In response to the anticipated scarcity of terrestrial land resources in the coming years, the acquisition of marine mineral resources is imperative. This paper mainly summarizes the development of …

The nascent industry of deep-sea mining threatens the health, and perhaps the very existence, of deep ocean communities. It would destroy the physical structures of the seafloor and the ecosystems they house, kick up sediment plumes that smother organisms, alter ocean chemistry across many kilometers, and create noise pollution in the …

Deep Sea Mining • Marine mammals: whales, dolphins, seals, dugongs • It is a relatively new technology globally with considerable uncertainty regarding the potential for environmental impacts • In most mining locations, the biological environments are often poorly understood by comparison to terrestrial environments
