The Antarctic Ocean is the coldest ocean in the world. Its temperatures reach minus 2 degrees Celsius in what is referred to as the Antarctic bottom water.Know More
The water at the surface of the Antarctic Ocean can be minus 2 degrees Celsius, which is below the zero degrees Celsius freezing point for water, explains the National Oceanic and Atmospheric Administration,. However, due to the high concentration of salt in the seawater, it is still liquid at this temperature.
Oceanographers have found that the Antarctic bottom water supply has been reducing an average of eight million metric tons per second over the past few decades. They argue that this decrease is the result of changes in Earth's climate.Learn more about Weather & Tides
Surface ocean currents are caused by winds. Wind currents run in certain directions because the earth rotates. Winds go to the right in the northern hemisphere and to the left in the southern hemisphere.Full Answer >
Ocean currents equalize global temperatures by moving warm water from the equator to the polar regions and returning cold water. The majority of the sun's heat is absorbed by the oceans around the equator. If ocean currents did not distribute this heat, global temperature fluctuations would be far more extreme.Full Answer >
