| Definition | The ocean mixed layer is the upper part of the ocean, regarded as being well-mixed. The base of the mixed layer defined by "temperature", "sigma", "sigma_theta", "sigma_t" or vertical diffusivity is the level at which the quantity indicated differs from its surface value by a certain amount. A coordinate variable or scalar coordinate variable with standard name sea_water_sigma_theta_difference can be used to specify the sigma_theta criterion that determines the layer thickness. Sigma-theta of sea water is the potential density (i.e. the density when moved adiabatically to a reference pressure) of water having the same temperature and salinity, minus 1000 kg m-3. The quantity model_level_number_at_base_of_ocean_mixed_layer_defined_by_sigma_theta is sometimes referred to as the "bowl index". | ||
