BioExpedition.com states that the average temperature of an ocean biome, which is made of saltwater, is 39 degrees Fahrenheit. The temperature of ocean biomes changes depending on the depth of the water, the wind and the presence of sunshine.
The ocean biome occupies around 71 percent of the Earth's surface, BioExpedition.com explains. Scientists estimate that every gallon of water in the ocean contains 1 cup of salt. There are five ocean biomes: the Pacific Ocean, the Atlantic Ocean, the Arctic Ocean, the Indian Ocean and the Southern Ocean. These oceans are connected with major seas, such as the Caribbean Sea, the South China Sea and the Mediterranean Sea.
The National Center for Ecological Analysis and Synthesis explains that the marine biome greatly influences the terrestrial climate. The ocean significantly influences the weather in various places, and it affects coastal temperatures. It also provides wind that circulates air and rain for crops. Ocean temperatures range from close to freezing point at the pole and deep in the waters to warm temperatures at tropical clear waters. The sun’s heat only warms the water surface. Deep down, oceans are generally dark and cold.
According to SoftSchools.com, temperatures of the oceans vary, and ocean water constantly moves. Cold water moves in from the poles, whereas warm water moves in from the tropics. The ocean is generally more salty in tropical regions, because the water evaporates, which leaves more salt in the ocean.
