Definition
The chemical composition of the ocean corresponds to the composition of its major and minor dissolved ions (Na+, Mg2+, Ca2+, K+, Sr2+, Cl−, SO4 2− HCO3−, Br−, CO23−, B3+,4+, F−). The major ion content is considered relatively constant and defined as salinity, which is a measure of the total dissolved salts in seawater. The chemical evolution of the terrestrial oceans is controlled by complex interactions between the Earth system reservoirs, namely the geosphere (mantle and crusts), the biosphere, the atmosphere, and the hydrosphere itself.
Overview
Ocean Chemistry: The Result of Complex Interactions in the Earth System
Table 1resume the average chemical composition of the Earth’s modern oceans with the concentrations of the main ions dissolved in the seawater (in mol/g) and corresponding to an average salinity of 35 g/L (or ca 35,000 ppm, being the density of water equal to 1.025 kg/L). Salinity in the present oceans is relatively constant, between 31 and 38 g/L, yet...
