What 3 factors affect the density of sea water?
Temperature, pressure, and common ion effect
List the reasons for variations in salinity in the various oceans?
Salinity can vary because of water temperature, rivers emptying into the ocean and mixing with ocean water, ice forming or melting, evaporation and precipitation. I think temperature is the biggest reason.
How does the calinity of water effect temperature and water currents?
Salinity, or saltiness, affects how readily the water changes temperatures as well as its density. Because of this, currents in the water can arise not only from the difference in temperature, but also from the density difference, which comes from the salinity itself.
Why does salinity cause a decrease in dissolved oxygen?
When an ionic salt like NaCl is added to water, the ions from the salt introduced will attract the water molecules in an effort to "solvate" the ions. This has the tendency to decrease the weak affinity of non-polar oxygen molecules to water and drive the dissolved oxygen out of the polar water. In general, the solubility of a gas in a solvent is affected significantly by the presence of other solutes in the solution.
How does the amount of salt in water affect the density?
General Answer:An increase in salinity causes a increase in density and conversely, a decrease in salinity causes a decrease in density. The effect is quite linear, though it has a temperature dependence that affects how much the density changes.Specific Answer:Density = M/V, so density of a substance increases if the mass increases or the volume decreases or, if both change, density increases if the mass increases faster than the volume decreases.The average density of water at the ocean's surface is about 1.025 g/ml or 2.5 % greater than pure water. This is due to the mass of added sea salts which is 3.5% or .035 g/ml. The added sea salts have a small effect on the volume, so the resulting combination is more dense than pure water.Salt has 2.165 grams per milliliter and water is 1 gram per milliliter, so if you just added one milliliter of salt and that displaced one milliliter of water, the change in mass would be 1.165 grams. Alas, that is not even close. Adding one milliliter of sodium chloride to a liter of water will only increase the volume by about one half of a milliliter.Beyond that sodium has an atomic mass of about 23 and chlorine about 35.5, while a water molecule's mass is about 18. So the components of salt are heavier than the components of water.If one takes all the factors into account, one is eventually led to the conclusion that adding salt to water does not take up the volume expected and does not increase the density exactly how you might expect and there must be some rearrangement of the molecules of water that affects how closely they fit together. This is, in fact, true and has been the subject of much study and there is much more known about this.

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
Will salinity increase or decrease with depth at high latitudes?
No, because the heavy precipitation of the tropical region causes the surface salinity to decrease. The salt moves to the bottom. Remember that rainwater is fresh.
What relationship does ocean circulation patterns and marine foodchain have?
they both have a relationship with each other and it is they both have a pattern and the effect when a el nino hit the ocean circulation patterns is when theres diffrent patterns and it will also have a totally diffrent circulation and the marine food chain will be diffrent increase in turbidity a decrease in salinity and
What do you call deep ocean circulation driven largely by variations in water temperature and salinity?
thermohaline
What is the driving force of deep-ocean circulation?
Deep ocean circulation(90% of ocean water) is caused by differences in temperature, salinity and suspended load. It is referred to as "Thermohaline"- meaning heat and salt- circulation.
Would salinity increase or decrease in an estuary during spring floods?
When the river brings in extra water, such as during periods of flooding, the salinity, or the amount of salt, in the water of the bay will be reduced.
What two characteristics of water combine to form a thermohaline?
temperature and salinity
