what is the relationship between salinity and density of ocean water

He theorized that there were density differences between the two seas causing an Examine the effect temperature and salinity have on the density of water. The determination of salinity by means of electrical conductivity relies on a constant salt composition in the North Atlantic Ocean, as standard. Water that is more dense will sink to the ocean floor. -Because of the connection among temperature, salinity and density, some currents.

The Ocean and Temperature

Temperature Temperature really is a measure of energy. The greater the energy, the higher the temperature.

When temperatures are high, the atoms in matter become "excited" from the energy and start to expand. Molecules, which are made up of atoms, also expand in this way.

This expansion results in lowered density.

In the ocean, warmer water expands just like any other matter, and following the principle of density, it rises to the top of the ocean. The cooler water, which is more dense than the warm water, sinks to the bottom and takes up the space left by the rising warm water. The result is a convection current. Sciencing Video Vault Salinity, Density, and Temperature When the water molecules of the ocean become heated, they expand. Extra space is created by this expansion into which salt and other molecules e.

Density of Ocean Water - Windows to the Universe

Since warmer water thus can hold more salt and other molecules than cold water; it can have a higher salinity. To relate this to ocean currents, the higher the salinity of ocean water, the more dense it becomes. When the salinity is high enough, the water will sink, starting a convection current.

This means that cold water can sit on top of warm water if the warm water has a high enough salinity, and that the natural flow of a current actually can be reversed based on the related density, salinity and temperature of the ocean water. Sources of Salt and Other Minerals The salt and other minerals that are in ocean water and which affect ocean currents come from several places. 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.

CC.6 Salinity, Temperature, Pressure, and Water Density

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.

Factors Affecting the Movement of Ocean Water - Geography UPSC IAS

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.
