Concentration isosurface c = 0.25 at t = 10 (Re = 6000, v s = 0.005, N = 2.09, m = 0.0744). The iso-surface reveals the global structure of the envelope of a hyperpycnal current upon destibalization. The lobe-and-cleft instability is clearly visible at the head of the current as hills and crests form in the spanwise direction. This instability propagates in the body of the current and destabilises the large 2D vortical structures initially present. The largest wavelength corresponds to the initial dominant mode of the instability and dictates the width of the domain necessary to observe the instability at this given Reynolds number
