Sentences with phrase «abyssal water warming»

Professor Alberto Naveira Garabato from the University of Southampton, the lead scientist of DynOPO, said: «The Orkney Passage is a key chokepoint to the flow of abyssal waters in which we expect the mechanism linking changing winds to abyssal water warming to operate.

Not exact matches

Faster flow is more turbulent, and in this turbulence more heat is mixed into AABW from shallower, warmer ocean layers — thus warming the abyssal waters on their way to the Equator, affecting global climate change.

Along one string of sites, or «stations,» that stretches from Antarctica to the southern Indian Ocean, researchers have tracked the conditions of AABW — a layer of profoundly cold water less than 0 °C (it stays liquid because of its salt content, or salinity) that moves through the abyssal ocean, mixing with warmer waters as it circulates around the globe in the Southern Ocean and northward into all three of the major ocean basins.

The warmth is eventually diluted into the frigid (3C) abyss by a factor of 10 to 1 (the ratio of cold abyssal water to warm surface water).

Purkey, S. G. & Johnson, G. C. Warming of global abyssal and deep southern ocean waters between the 1990s and 2000s: Contributions to global heat and sea level rise budgets.

Unlike the surface ocean, which is in contact with the warming atmosphere, these abyssal waters are thousands of meters below the surface.

As it travels north, the abyssal water slowly warms from geothermal heating below and as a result of mixing with warmer waters above, ultimately becoming less dense.

If the other processes that warm abyssal waters (mixing and geothermal heating) have not changed, then this change could explain the abyssal ocean warming that we are observing.
