The study of the chemical composition of seawater is known as chemical oceanography. Chemical oceanographers research the interactions between organic and inorganic substances, as well as the ocean's biological, physical, and geological environments, in order to better understand how physical processes and exchanges with the environment, biosphere, and geosphere affect marine chemistry.
