Question

Explain about the vertical and horizontal distribution of salinity

Answer 1

Salinity is the term used to define the total content of dissolved salts in sea water.It is calculated as the amount of salt (in gm) dissolved in 1,000 gm (1 kg) of seawater.It is usually expressed as parts per thousand or ppt.Salinity of 24.7 (24.7 o/oo) has been considered as the upper limit to demarcate ‘brackish water’.

Role of Ocean Salinity

Salinity determines compressibility, thermal expansion, temperature, density, absorption of insolation, evaporation and humidity.It also influences the composition and movement of the sea: water and the distribution of fish and other marine resources.
