There are three ways to find the salinity of a body of water.
The Evaporation Method:
Evaporate the salt water, and measure the weight of the salt residue.
Ex: 2g of Salt Residue, after evaporation, and 50 cubic cm of water it was taken from.
Divide the grams of salt by the weight of the water and multiply by 1000 to find the salinity in (parts per thousand). Salinity = 40 parts per thousand.
The Drop Method:
Since many sailors could not evaporate sea water, because it was too hazardous, they developed the Drop Method. In this method, you have to add drops of silver nitrate into the water, until it turns cloudy.
Ex: 20 drops of silver nitrate until cloudy.
You have to divide the drops of silver nitrate by 0.55 because no matter what type of salt it is, there will always be 55% chlorine in it. The drops of silver nitrate react with the chlorine.
The Electrocution Method:
Keep a control and measure the # of volts that react with the salt. This requires a graph that corresponds your manipulated and responding variables. Then to find the salinity extend your graph find the salinity that matches your # of volts, or the other way around.

Oceanographers measure the salinity of the ocean by hand held refractometer, hydrometer, and conductivity meter.

Salinity is a measure of how salty water is. Ocean water is more salty in some places than in others. The answer is yes, places where rivers pour fresh water into the ocean have low salinity because fresh water is normally cold and in warm areas, ocean water evaporates quicker. When this happens, salt is left behind and the ocean water has a higher salinity.

You could increase the salinity of the ocean by adding salt or removing water (ie: by evaporation).
The lowest areas of salinity in an ocean are near where fresh water rivers empty into them. This is because the influx of fresh water creates an area of lower salinity compared to the remainder of the ocean.
