Figure 5 | a, Model particulate plume on the 10^th day after start release (at the end of eddy I passing period) containing 5.7·10⁵ individual particles suspended in a water (grey dots) and settled on seafloor (colours). The area with substantial accumulated sediment layer thickness (in m) is shown over bathymetry (grey lines, 50 m). Points along the nodule collector tracks were aligned with equally-spaced Archimedes spiral and shown on a dashed in-cut to indicate the scale of the harvested zone during the last day (red) and since the beginning of experiment (green). Red and green triangles indicate three mooring sites, labelled with M-1, M-2 and M-3, and two sediment core sampling sites⁵³ respectively. b, Settling footprint after 10 days of a similar SPM release over period II without eddy impact.
