In a changing climate, a description of the permanent pycnocline, which is globally coherent and independant from any thermohaline properties, is required in order to provide a reference state for the identification of the warm water sphere variability. Using a recently developped pattern recognition method applied to stratification profiles from Argo in situ data, this study presents such a reference state for the subtropical latitudes and the 2000-2015 period. With this method, a mode water core is recognised as a stratification minimum that is, possibly temporarely, trapped below the seasonal pycnocline. The permanent pycnocline is recognised as the stratification maximum localised below that mode water core.
