Fig. 7: Richardson number (Ri) estimated from seismic data.

Ri (in color) overlays the seismic transects (in gray). a–c correspond seismic lines 1294, 1296, and 1300, respectively. The blue areas indicate Ri <0.25, where shear instability is dominant. Eddy numbers (E1, E2, E4, and E5) have been marked.
