<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Thermocline represents vertical transition zone of oceanic water and it is between the upper and the lower layer of the ocean. It is characterized by rapid rate of decrease of temperature with increasing depth. There also exist seasonal thermoclines between the depth of 40 m and 100 m. These are formed due to heating of water surface through solar radiation during summer season.
