Title: How bioturbation supports manganese nodules at the sediment-water interface
Abstract: Theoretical considerations suggest that oceanic manganese nodules are supported at the sediment-water interface by bioturbation. Bioturbation can cause a horizontal Stokes transport from regions of high biological activity to regions of low biological activity. Less sediment motion might be expected beneath a nodule than in the surrounding sediment because a nodule is a barrier to the foraging activities of macrobenthic organisms and also because there is probably less food directly beneath the nodule than in the surrounding sediment. Sediment velocities, calculated from particle mixing coefficient of pelagic sediment, appear to be sufficient to prevent nodules from being buried.
