Density is affected by both temperature and salinity. The colder the temperature and the saltier the substance, the greater the density.

Is a high salinity solution less dense than water?
No, increasing salinity results in higher density. This density increase means you will also be able to float more easily in more saline water. The higher the salinity the lower the temperature it will freeze.
What is the density in seawater determined by?
Seawater's density varies by temperature and salinity. I.e., cold water is more dense than warm water, and water with a higher salinity (more dissolved salt) is less dense than water with a lower salinity.
How is thermohaline circulation influenced by salinity and temperature?
A: It is driven by density gradients, which are affected by salinity and temperature, with cold water and water with higher salt concentrations being more dense
In addition to salinity what factor affects the density in sea water?
Density of seawater is largely a function of two factors: depth, that is, the deeper water is more dense than water at shallower levels; and temperature - water at higher temperatures is less dense than cooler water. Salinity is also a factor, but that's a localized phenomena simply because all the worlds oceans are in fact one large ocean and maintains an average overall salinity.
What are the four things that affect ocean's salinity?
Salinity is affected by temperature of the water, amount of salt per area, how cool it is, and the amount of water per area. If it's hot, the water will evaporate leaving more salt behind. The more salt you add, of course you will have a higher salinity. If it is cold, ice forms and pushes out the salt into the water below. And if you add more water, there will be more water to hold the salt, thus lowering the salinity.
Which part of the water column is the saltiest?
Surface water has the highest salinity, however it is also the warmest, and because temperature has more effect on the density than the salinity, it rises to the top.
How does temperature affect the density of ocean 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.
How does salinity affect the density of the ocean water?
Dissolving salts in water increases the density slightly. Ocean waters have an average density about 2.5% greater than fresh water. The Dead Sea has a much higher density, somewhere roughly near 20% greater than fresh water due to its 30% salinity level.
An object floats in sea water more readily because of sea water's?
Density. The amount of salt and minerals (salinity) increases the water's density and affects the ability of an object to sink in saltwater - for example, it is nearly impossible to sink if you're swimming in the Great Salt Lake in Utah due to the high salinity of the lake. The higher the salinity content, the harder it is to sink an object.

How do temperature and salinity different produce convection currents?
The large amount of solids dissolved in ocean water, which is the salinity, makes it more dense than fresh water. Cold water is denser than warm water (temperature). These differences in density produce convection currents
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)
