Salinity is directly positively related to seawater density.On an average, seawater density increases with increasing salinity and vice versa.E.g. Density of pure water is 1.00 g/cm3 and density of water with 35% salinity is 1.028 g/cm3.
Northeast Atlantic and the adjacent waters of the Arctic extending from Norway to Great Britain and Iceland constitute the second major fishing region. This region is known for the world’s best cod-fishing grounds.
