... Abstract In the emerging industry of deep-sea mining for minerals and deposits (e.g., polymetallic nodules for nickel, cobalt, copper, and manganese), more data is required to understand the effects of sediment plume generation and predict the distribution of disturbed sediments. There are two...

... technique used to analyze the degassed water discharge plume from that facility and describes the dynamics of the plume. We used a Reynolds-Averaged Navier Stokes (RANS) model to analyze the dynamics of the degassed water plume. The density of the water, and hence the plume dynamics, is heavily affected...
