Sentences with phrase «cold saline waters»

This system involves the sinking of cold saline waters in the subpolar regions of the oceans, an action that helps to drive warmer surface waters poleward from the subtropics.

Not exact matches

Qualitatively, the slow ventilation is consistent with very saline and very cold deep waters reconstructed for the last glacial maximum (Adkins et al., 2002), as well as low glacial stable carbon isotope ratios (13C / 12C) in the deep South Atlantic.

This is what happens in our model events pictured above: during cold phases in Greenland, oceanic convection only occurs in latitudes well south of Greenland, but during a DO event convection shifts into the Greenland - Norwegian seas and warm and saline Atlantic waters push northward.

2 — previously warm saline surface water, now wind cooled (cold) saline surface water sinks to depths up to 2000m.

If the putative Arctic magnification of global warming prevents the cold air outbreaks from cooling the northward moving saline water, it may not cool enough to become convectively unstable.

Due to the refrigerator effect, cold saline Antarctic Bottom Water (proto - AABW) began to dominate the ocean floor.

Contributions of Warm Saline Deep Water (WSDW) diminished, and the influential Antarctic Intermediate Water (AAIW) was increasingly cooled by much colder Antarctic Bottom Water.

Climate Alchemy and probably most scientists not taught chemical thermodynamics don't realise that the main heat transfer term in the oceans is the partial molar enthalpy transferred when the fresh, cold water sinking from melting ice in the Antarctic and Arctic summers is made more saline when it mixes with the warmer, more saline surface water for which solar energy has partially unmixed the ions.

Upwelling is the other side of the coin of sinking cold and saline water in the north which drive the great ocean currents.

A faster AMOC tends to transport more saline water to the North Atlantic subpolar region, where it loses some heat to the cold atmosphere and sinks.

Surface water tends to be less saline and colder water of low salinity is less dense and so rises potentially reversing the «normal» situation.

Cold water sinks readily in polar regions, as the surface water tends to be closer to freezing, as well as being fresher from ice melt, and therefore less dense than the inflowing currents, which are in turn are rendered more saline by the fresh water freezing out.

I'm not sure whether this is off topic, but I have read in other threads that there is less cold water plunging to the ocean floor around Antarctica (and presumably the Arctic too) due to the sea water becoming less saline due to increased precipitation and melting polar ice.

Salinity changes water density too and allows warmer more saline water to sink beneath colder fresher water.
