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.

gets colder
The density of ocean water is calculated using the temperature, salinity, and pressure of the water. These factors impact the water's mass and volume, which determines its density. The density of ocean water can vary depending on these factors, with colder, saltier, and deeper water typically being denser.
No when there density increases
The density of water increases with depth due to the increase in pressure. As water molecules are packed closer together under high pressure, the density of water increases. Therefore, in deep water where the pressure is higher, the density of water is also higher.
The density of water remains constant regardless of the volume or shape of the container it is in. This is because the mass of water and its volume stay the same, resulting in the same density for both a pool and a cup of 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.
Pressure increases the density of sea water because it compresses the water molecules closer together, reducing the volume occupied by the same amount of water. As pressure increases with depth in the ocean, the density of sea water also increases. This effect is known as compressibility.
the density of sea water increases as salinity increases and temperature decreases
depth and salinity increases density of sea water increases
Water increases in density until 4 degrees Celcius, when its density starts to decrease again due to hydrogen bonding. (see Wikipedia.org for more.) As water moves away from the equator, it gives off heat. As it cools, its density increases.
the density of sea increases with depth
Yes, salt increases the density of water by adding more solute particles, which increases the mass per unit volume. This phenomenon is known as salinity and it causes water to become denser and heavier, affecting factors like buoyancy and circulation patterns in the ocean.
Gets colder.
It's due to the chemical reaction of the co2 on the ocean water, since there is no salt the density increases
oceans stuff
-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)
