深海采矿可能只有几年的时间，但社会正在努力评估其积极方面，例如增加电池生产金属的供应以推动绿色革命，以及潜在的巨大环境影响。从深海开采多金属（锰）结核可能是第一个目标矿产资源，每个矿场每年都会对数百平方公里的海底产生直接影响。然而，采矿活动也会导致大量沉积物羽流的产生，这些沉积物羽流将从矿场扩散出去，并对更广泛的地区产生直接和长期影响。我们讨论了采矿车辆在海底附近产生的羽流可能产生的影响，以及如何在如此具有挑战性的环境中测量它们。世界各地正在开发几种不同的采矿车辆，根据其设计，有些车辆可能会产生比其他车辆更大的羽流。我们讨论如何比较这些车辆，以便选择更好的工程设计，并鼓励在处理羽流产生和扩散方面进行创新。这些考虑因素将有助于国际海底管理局 (ISA) 履行其促进最佳可用技术 (BAT) 和最佳环境实践 (BEP) 的承诺，该机构的任务是监管大部分深海采矿活动。
Deep-sea mining may be just a few years away and yet society is struggling to assess the positive aspects, such as increasing the supply of metals for battery production to fuel the green revolution, versus the potentially large environmental impacts. Mining of polymetallic (manganese) nodules from the deep ocean is likely to be the first mineral resource targeted and will involve direct impacts to hundreds of km2of seabed per mine per year. However, the mining activity will also cause the generation of large sediment plumes that will spread away from the mine site and have both immediate and long-term effects over much wider areas. We discuss what the impacts of plumes generated near the seabed by mining vehicles may be and how they might be measured in such challenging environments. Several different mining vehicles are under development around the world and depending on their design some may create larger plumes than others. We discuss how these vehicles could be compared so that better engineering designs could be selected and to encourage innovation in dealing with plume generation and spread. These considerations will aid the International Seabed Authority (ISA) that has the task of regulating mining activities in much of the deep sea in its commitment to promote the Best Available Technology (BAT) and Best Environmental Practice (BEP).
