Figures S1 to S4

Figure S1. Vertical distribution patterns of the density (units in kg/m3) and path lines in the non-reactive simulation with a density-salinity ratio of 0.67 (see eqn. 4) and an upper concentration limit (NRL.67) at different time steps (1, 20, 40, 70 and 2,000). Notice the non-uniform color scale in the density patterns. Notice that the path lines can be interrupted in areas of high flow velocities, where the path line density increases.

Figure S2. Vertical distribution patterns of the density (units in kg/m3) and path lines in the non-reactive simulation with a density-salinity ratio of 0.67 (see eqn. 4) and an unlimited upper concentration (NRU.67) at different time steps (1, 20, 40, 70 and 2,000).
Notice the non-uniform color scale in the density patterns. Notice that the path lines can be interrupted in areas of high flow velocities, where the path line density increases.

Figure S3. Vertical distribution patterns of the density (units in kg/m3) and path lines in the non-reactive simulation with a density-salinity ratio of 0.81 (see eqn. 4) and an unlimited upper concentration (NRU.81) at different time steps (1, 20, 40, 70 and 2,000).
Notice the non-uniform color scale in the density patterns. Notice that the path lines can be interrupted in areas of high flow velocities, where the path line density increases.

Figure S4. Vertical distribution patterns of the density (units in kg/m3) and path lines in the non-reactive simulation with a density-salinity ratio of 0.61 (see eqn. 4) and an unlimited upper concentration (NRU.61) at different time steps (1, 20, 40, 70 and 2,000).
Notice the non-uniform color scale in the density patterns. Notice that the path lines can be interrupted in areas of high flow velocities, where the path line density increases.
