Polymetallic nodules, which contain high economic-value metals, such as manganese (~30wt%), Nickel (1.5wt%), Copper (1.4wt%), Cobalt (0.25wt%), Iron (6wt%), Aluminium (3wt%), are found naturally and in abundance on the seabed in some areas in the Pacific ocean and the Indian ocean. They are considered as an important resource manganese, and possibly some rare metals for future. However, nodule collection activities are likely to disturb the ocean floor and possibly re-suspend a large amount of sediment into the ambient water region. Environmental impact assessment from any technical activity on the seabed is mandated by the International Seabed Authority (ISA), a United Nation body. Many studies on chemical compositions and physical and rheological properties of the bottom-ocean sediment, sediment disturbance and subsequent sediment spreading, and possible responses of benthic communities to rise of sediment concentration in the ambient water have been extensively conducted. In the scope of this presentation, we would like to share some experimental and computational works on the sediment rheology, sediment disturbance, and sediment spreading that have been carrying out in the Keppel-NUS Corporation Laboratories, National University of Singapore.
