It's always worth remembering that the other end of the AMOC involves two main factors: (1) vorticity - mixing of heat from surface waters into the deep abyssal ocean (which decreases density causing the Atlantic Deep Water to start rising above the colder Antarctic Bottom Water) and (2) the wind - driven upwelling around the Antarctic Circumpolar Current.

The deep ocean and surface water don't overturn because of differences in density, so the exchange is via global circulation.

There are millions of tons of plastics present in our oceans, and these are constantly fragmenting into smaller and smaller pieces which are scattered throughout the water column and present, in different densities, throughout all the worlds oceans.

It seems that those who fear AGW (or at least some of them) do admit that it is not realistic to expect a planetary atmosphere such as ours to warm up oceans of water over the timescale required by AGW theory because of the huge volume and density of that water and thus the heat storage differentials.

The Atlantic overturning is driven by the differences in the density of the ocean water: when the warm, lighter water flows from south to north it becomes colder, denser and heavier, making it sink deeper and flow back southwards.

Due to the huge volume of sea water and the density differentials between air and ocean that would be impossible or would require such huge amounts of atmospheric heating and such huge lengths of time that for practical purposes it should be ignored.

Density currents are also caused by differences in the amount of salt (salinity) on the ocean water.

We saw in Section 2 that water densities (and hence volume) are quite variable throughout the oceans.

18 Deep Currents Deep currents are caused by differences in the density of ocean water.

Yes when fresh water ice melts in fresh water the water level doe snot change but I was referring to the oceans and they contain sea water of higher density than fresh water.

19 Deep Water Currents Make up about 90 % of oceans» water Differences in density cause them to Water Currents Make up about 90 % of oceans» water Differences in density cause them to water Differences in density cause them to move.

As the ocean warms, the density increasing causing the water to expand in volume.

Thermohaline circulation (THC)- Large - scale circulation in the ocean that transforms low - density upper ocean waters to higher - density intermediate and deep waters and returns those waters back to the upper ocean.

However, Earth's polar regions currently experience net precipitation, and the fresh water effect on the ocean density allows the surface to freeze without the need for the entire column of ocean water to reach the freezing point.

Sea level change - Sea level can change, both globally and locally, due to (i) changes in the shape of the ocean basins, (ii) changes in the total mass of water and (iii) changes in water density.

Water mass - A volume of ocean water with identifiable properties (temperature, salinity, density, chemical tracers) resulting from its unique formation proWater mass - A volume of ocean water with identifiable properties (temperature, salinity, density, chemical tracers) resulting from its unique formation prowater with identifiable properties (temperature, salinity, density, chemical tracers) resulting from its unique formation process.

Second, the ocean absorbs CO2 on average all across the lower density surface as the waters cool by radiation to space on their return to the poles.

As for heat hiding in the ocean depths, one must first heat water and at the same time increase its density, otherwise it will just float on the denser, colder water below.

My favorite possibility is that upwelling cold water west of South America lowers the ocean and air temperatures, and consequently raises the density of the atmosphere there.

Even if the system did not prevent that entirely it would take many thousands of years to have any measurable effect on the oceans at all due to the huge density differential between air and water and the volume of water involved.

Climate change can influence the distribution of dead zones by increasing water temperature and hence microbial activity, as well as reducing mixing of the ocean (i.e., increasing layering or stratification) of the Ocean — which have different temperatures, densities, salinities — and reducing mixing of oxygen - rich surface layers into the deeper parts of the Oocean (i.e., increasing layering or stratification) of the Ocean — which have different temperatures, densities, salinities — and reducing mixing of oxygen - rich surface layers into the deeper parts of the OOcean — which have different temperatures, densities, salinities — and reducing mixing of oxygen - rich surface layers into the deeper parts of the OceanOcean.

Everything else being equal, warm water has a lower density than cold water and won't sink into the deep cold oceans.
