Figure 9 . Along-slope variability of the diagnostics averaged within 1° bin in longitude over the 1,000–3,000 m isobaths. (top) Inversed gradient and standard deviation of the CDW thickness. (middle) thickness-based diffusivity and eddy velocity. (bottom) Isopycnal diffusivity for CDW. Red shades are the locations of CDW intrusion described in Yamazaki et al. (2020), where “Wx” is warm signals in the Australian-Antarctic Basin, “PB” is for the Prydz Bay, and “LHB” is for the Lützow-Holm Bay.
