Where the steps occurred

•Index=% of DTpycnocline in zero bin

•Highest near topography, could be due to internal wave breaking or bergs?

•Density Ratio, Rr is also higher at higher layer index, putting further doubt on DDC, but this is preliminary…

•Rr<2 for instability (Huppert, 1971) of diffusive regime.
