Media 3

Supplementary Media 3 | Animation shows a particulate matter plume spreading over bathymetry (lines, 50 m increment) during 10 days of model simulation. Plume contains 5.7·10⁵ individual suspended particles in water (red) and settled (colours, m) on the seafloor. Points along the nodule collector tracks were aligned with equally-spaced Archimedes spiral, and shown on dashed in-cut to indicate the scale of the harvested zone during the last day (red) and since the beginning of experiment (green).
