For the ecological risks of sediment plumes induced by deep-sea mining disturbances, a high-fidelity numerical simulation framework was developed based on the Navier-Stokes equations, integrating high-resolution 3D topography, seawater density stratification, unsteady tidal dynamics, and multi-scale circulation constraints. A typical seamount mining area southwest of the Canary Islands in the Atlantic Ocean was taken as the research subject, and the multi-stage coupled evolution mechanism of the plume from initial disturbance to long-range ocean current transport was revealed after Spearman data validation. The study found that, constrained by the complex seamount topography and the geostrophic deflection effect, the horizontal path of the plume deflects significantly and exhibits a rotational diffusion pattern, which prolongs the residence time of particulate matter in the local water body. Modulated by the flow-around dynamic field of the seamount and the rotational shear mechanism, the plume evolves from a near-field point source discharge into a far-field anisotropic stretching structure. Due to the inhibitory effect of the stable deep-sea density stratification, the plume spatially exhibits a hierarchical dilution pattern.
