Mixed layer depth is defined using a finite difference method based on temperature and σθ at 10 dbar. Two pairs of the difference criteria are used such as (Δσθ=0.03kg/m3 and ΔT=0.2°C) and (Δσθ =0.125kg/m3 and ΔT=0.5°C). The mixed layer depth is estimated from a minimum thickness of either Δσθ or ΔT. Isothermal layer thickness and isopycnal thickness are estimated using two criteria, respectively. Producing parameters of mixed layer depth, isothermal layer thickness and isopycnal layer thickness are listed below.

1. Mixed Layer Properties (depth definition : shallower thickness, either Δσθ=0.03kg/m3 or ΔT=0.2°C)
2. Mixed Layer Properties (depth definition : shallower thickness, either Δσθ=0.125kg/m3 or ΔT=0.5°C)
3. Isothermal Layer Properties (thickness definition : ΔT=0.2°C)
4. Isopycnal Layer Properties (thickness definition : Δσθ=0.03kg/m3)
5. Isothermal Layer Properties (thickness definition : ΔT=0.5°C)
6. Isopycnal Layer Properties (thickness definition : Δσθ=0.125kg/m3)
