The salinity of the ocean was much higher than I thought it would be.
The top most layer has more salinity. But ignoring thermo-haline currents.
The warmer a solution becomes, the higher the salinity can be. Warmer water can have more of a salt dissolved in it.
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.
the higher the salinity the more easily an object can float
Hypersaline refers to a body of water that has about 40 parts per mil salinity which is much higher than the salinity for average ocean water which is about 35 parts per mil salinity.
Yes, beaches have higher level of salinity now compared years ago. This is one of the impacts of global warming. In effect, more aquatic animals are becoming extinct.

Water salinity describes the amount of salty minerals dissolved in a sample of water. It would therefore make no difference whether the water is warm or cold, since you would have the same amount of salt dissolved in the water per cm3 of water. Salinity would change if you added more water, or if the water was so hot that some of it evaporates, leaving all the dissolved solids behind, but decreasing the amount of water it is dissolved in.
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
Yes, salinity is higher in dry, hot areas because the high evaporation rate leaves behind salts dissolved in the water.
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.
