Detailed explanation-1: -Salinity is the measure of the number of grams of salts per kilogram of seawater, which is expressed in parts per thousand. Parts per thousand can be defined as how many parts, or grams, of salt there are per thousand parts, or kilogram (1, 000 g), of seawater. The symbol for parts per thousand is ‰.
Detailed explanation-2: -The term “salinity” refers to the concentrations of salts in water or soils. Salinity can take three forms, classified by their causes: primary salinity (also called natural salinity); secondary salinity (also called dryland salinity), and tertiary salinity (also called irrigation salinity).
Detailed explanation-3: -Salinity-Salinity is the amount of salt in grams present in 1000 grams of water. The average salinity of the oceans is 35 parts per thousand.
Detailed explanation-4: -Salinity is the measure of the concentration of dissolved (soluble) salts in water from all sources. In general: surface water salinity is described by units of “electrical conductivity” (EC) groundwater salinity is described by units of “parts per million” (PPM)
Detailed explanation-5: -Hydrometers are used to measure the oceans salinity, or how “salty” the ocean is. To use a hydrometer you must fill up the tool with saltwater and then observe how much the lever is raised by the salinity. We like to use the measurement PPT or Parts per Thousand.
