The significance of the pycnocline in tropical lakes

The vertical temperature profile is a poor indicator of sratification in most tropical lake. Data from Lake Bunyonyi, Uganda, showed, however, that the density profile highlighted discontinuity layers whieh were not obvious from the temperature profile, It is suggested that the vertical density profile and the region of maximum discontinuity, the pycnocline, could be adopted as a useful index of stratification especially in tropical lakes.
