| Water temperature profiles showed persistent thermoclines in 10-30 m and 55-75 m layers. |
| Photography is not easy in the waters around Cocos, because of the continuously varying thermoclines. |
| Visibility is affected by the plankton levels and thermoclines that refract the light so that an otherwise perfect image can get a woolly edge. |
| Silt clouds may travel over great distances by means of thermoclines and currents, enlarging the area affected by trenching or jetting. |
| However, the water is subject to thermoclines, so the comfortable surface temperatures extend only a few metres down. |
| These lakes have permanent thermoclines, small littoral zones, and deep hypolimnia. |
