How does the density of water affect ocean currents and movement of water?

What water temperature increases density of ocean water?
When the ocean water freezes, it increases the salinity. When the ocean water freezes at the surface, ice will float on top of water because ice is less dense than liquid water. The dissolved solids are squeezed out of the ice and enter the liquid water below the ice. This increases the salinity of the water. The density of the water also increases.

What factors affect the density of ocean water?
The two factors of primary importance affecting water density are temperature and salinity. These are an important influence on global ocean currents. The process of convergence and divergence also plays an important role on controlling the water density of Oceans. In addition, the density of water increases slightly with increasing pressure and this can become a factor at the tremendous pressure of the deep ocean.

What is the accepted density of Seawater?
The density of pure water is 1000 kg/m3. Ocean water is more dense because of the salt in it. Density of ocean water at the sea surface is about 1027 kg/m3. There are two main factors that make ocean water more or less dense than about 1027 kg/m3: the temperature of the water and the salinity of the water. Ocean water gets more dense as temperature goes down. So, the colder the water, the more dense it is. Increasing salinity also increases the density of sea water. Less dense water floats on top of more dense water. Given two layers of water with the same salinity, the warmer water will float on top of the colder water. There is one catch though! Temperature has a greater effect on the density of water than salinity does. So a layer of water with higher salinity can actual float on top of water with lower salinity if the layer with higher salinity is quite a bit warmer than the lower salinity layer. The temperature of the ocean decreases and decreases as you go to the bottom of the ocean. So, the density of ocean water increases and increases as you go to the bottom of the ocean. The deep ocean is layered with the densest water on bottom and the lightest water on top. Circulation in the depths of the ocean is horizontal. That is, water moves along the layers with the same density. The density of ocean water is rarely measured directly. If you wanted to measure the density of ocean water, you would have to collect a sample of sea water and bring it back to the laboratory to be measured. Density is usually calculated using an equation. You just need to measure the salinity, temperature and pressure to be able to find density. These measurements are often made with a CTD instrument, where the instrument is placed in the ocean water from a ship or a platform.

Asked in Math and Arithmetic
Which two factors influence seawater density?
-As temperature increases, density increases (due to thermal expansion) -As salinity increases, density increases (due to the addition of more dissolved material) -As pressure increases, density increases (due to the compressive effects of pressure) of these 3 factors, only temperature and salinity influence the density of surface water. Pressure influences seawater density only when very high pressures are encountered, such as in deep ocean trenches.'' (Thurman H., et al, 2002)
Asked in Oceans and Seas
What are deep ocean currents and density currents?
The same thing! Deep Currents Occur when the density of the water increases. Density is based on two main things it is the civility is how much salt and other solids are in it and it is also the temperature of the water.The lower the temperature the lower the dense the water becomes. The denser the water the more it was to go down. The less dense the water wants to rise. The temperature is what causes the dense. Deep current:A streamline movement of ocean water far below the surface.

What is water density due to salinity of water?
Asked in Oceanography
How do salinity and temperature affect the density of water?
What is the relationship between salinity and density in seawater?
I think that as the salinity increases, density increses. The minerals that contribute to the salinity of sater, such as sodium and chloride, are denser that water. Thus, when the dense particles are added, the density of the water increases I think that as the salinity increases, density increses.
