La thermocline permanente est la zone de transition entre les eaux chaudes de l'océan superficiel (au-dessus de 15–20 °C) et les eaux froides de l'océan profond (au-dessous de 4–6 °C). Elle est située sous la thermocline saisonnière, limite inférieure de la couche de mélange océanique de surface, et jusqu'à environ 1000 m de profondeur. En hiver la thermocline saisonnière disparaît (sauf dans les zones tropicales), et seule subsiste la thermocline permanente.
