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 happens if the density increases?
Density is a characteristic of a given material. Water, for example, has a certain density (which is somewhat dependent upon temperature but let's say that the temperature is constant). It does not matter how much water you have, it will all have the same density. One teaspoon has much less mass, but the same density as an entire ocean.
What is the average density of seawater?
The density of surface seawater ranges from about 1.020 to 1.029 g·cm-3, depending on the temperature and salinityThe average density of seawater at the surface of the ocean is 1.025 g/ml; seawater is denser than freshwater (which reaches a maximum density of 1.000 g/ml at a temperature of 4°C) because of the added mass of the salts.
Describe the density and temperature characteristics of water in equatorial regions?
I think the density is more fresh water in the ocean
By using information about the temperature and salinity of ocean water oceanographers can determine the?
density
What does the density of water do As the temperature of seawater decreases?
It increases - until within 4 degrees of freezing, where it decreases.
The density of sea water increases as?
the density of sea water increases as salinity increases and temperature decreases
The density of ocean water increases when it?
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. Source: Science book.
The density of the ocean water increases when it?
gets colder
How do temperature and salinity relate to deep-current movement?
The density of the water increases with the salinity, so saline water is denser and sinks to the bottom. Temperature is also a factor, however. Cold, saline water is the densest
When the density of ocean water increase?
Gets colder.
How temperature affect the density of water?
The density of water increases as its temperature increases from 0 deg C to 4 deg C (the anomalous expansion phase). Above 4 deg C, the density decreases with temperature.
In general the density of sea water increases as?
salinity increases and temperature decreases....
Does water particles fall to the earths surface after their temperature increases?
No when there density increases
What happens if the density increases?

It does not matter how much water you have, it will all have the same density. One teaspoon has much less mass, but the same density as an entire ocean.
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)
What is the average density of seawater?

What information is used to calculate the density of ocean water?
Density is calculated from the temperature and salinity of the water.
