«Cold, deep water from this little area of the Nordic seas, less than 1 % of the global ocean, travels the entire planet and returns as warm surface water.

So the air was getting colder, but the deep ocean water was getting warmer, during the coldest periods of the Ice Age.

Warm and saline water transported poleward cools at the surface when it reaches high latitudes and becomes denser and subsequently sinks into the deep ocean.

About 19 months after the wind churned the ocean, cycling warm deep waters upward and sending the cold surface waters down, the Totten ice shelf was noticeably thinner and had sped up.

Deep ocean water, which is relatively warm, has been melting portions of the ice sheet at its base.

The study marks the first time that human influence on the climate has been demonstrated in the water cycle, and outside the bounds of typical physical responses such as warming deep ocean and sea surface temperatures or diminishing sea ice and snow cover extent.

Essentially, the researchers found that deeper warm water is increasingly mixing with the cool layer of water that traditionally lies atop the eastern part of the Arctic Ocean.

During the past 11,000 years, wind patterns have pushed warm waters from the deep ocean onto Antarctica's continental shelf

Arrays monitor circulating currents in the Atlantic Ocean, in which warm shallow waters move north (red), while cold deep waters move south (blue).

That means it sinks into the deeper layers of the ocean, and the contrast between this warm water and the undersea ice canyons contributes an unknown but substantial amount of sea level rise, said Josh Willis, an oceanographer at JPL in Pasadena, California.

Because such deep seawater circulates from the coast of Antarctica, this deep - water warming implies that the Southern Ocean drove the last major climate change.

Because existing phenomena — such as thermal expansion of water from warming — do not fully explain the corrected sea - level - rise number of 3.3 millimeters, stored heat in the deep ocean may be making a significant contribution, Cazenave said.

With higher levels of carbon dioxide and higher average temperatures, the oceans» surface waters warm and sea ice disappears, and the marine world will see increased stratification, intense nutrient trapping in the deep Southern Ocean (also known as the Antarctic Ocean) and nutrition starvation in the other oceans.

The deep circulation that drives warm surface waters north is weakening, leading to a cooling of the north Atlantic relative to the rest of the oceans.
