The study of temperature of the ocean is essential because-
1. The temperature of the ocean provides information on the global climate system.
2. It is also important for the study of marine ecosystems.
3. The temperature of the ocean water is responsible for the movement in the oceanic water.
4. Rising temperatures cause coral bleaching and loss of breeding grounds for marine fishes and mammals.
5. The study of temperature of the ocean can help in establishing marine protected areas and forming precautionary limits to prevent overfishing, protecting ocean ecosystems and shield humans from the effects of ocean warming.
