The density of seawater in different regions is generally 1.02-1.07, and the weight of the dissolved salts is different about 3.5% on average. It is recommended to control the proportion of salt in this range.
Seawater salinity is the ratio of the total dissolved solids to the weight of seawater in seawater, usually expressed in grams per kilogram of seawater.
