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
Deep water currents are caused by denser, colder water sinking to the bottom of the ocean while warmer, shallow water rises towards the surface. This is known as thermohaline circulation, while the continuous movement of deep water currents in the world's oceans is called the Global Conveyor Belt.Full Answer >
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 >
