Fig. 7
(a) Schematic showing the collector vehicle driving along line segment \(\mathcal {L}_n\) intersecting the gravity current it previously generated along \(\mathcal {L}_{n-1}\), the first and last 10m sections of the straight line \(\mathcal {L}_n\) are denoted \(L_1\) and \(L_6\). When in \(L_1\), the collector intersects the turbidity current generated 7.9 min prior to sampling (on average), and when in \(L_6\), the turbidity current was generated 15.4 min earlier. (b) The cumulative volume-based particle size distribution \(F^v\) shows the sampled suspended sediment during the line mining pattern detrained from gravity currents intersected at different times (dashed lines, dark green triangle, and light green diamond), and during two selfie experiments (solid lines, red circle, and orange square).
