The temperature of the oceanic water is important for marine organisms including plants (phytoplanktons) and animals (zooplanktons). The temperature of sea water also affects the climate of coastal lands and plants and animals therein.
The study of both, surface and subsurface temperature of sea water is significant. Standard type of thermometer is used to measure the surface temperature while reversing thermometers and thermographs are used to measure the subsurface temperature.

Temperature of Ocean Depends on following factors:
- Sources of Ocean heat
- Range of Ocean Temperature
- Distribution Patterns & Factors impacting distribution of temperature of Oceanic Water
- Horizontal Distribution of Temperature in Oceans
- Vertical Distribution of Temperature in Oceans
