Chemical oceanography is a field that involves the study of chemical processes in the ocean. It aims to explain the chemical composition of seawater and how it reflects the interactions between the ocean and the Earth's environment. Synonyms for chemical oceanography include marine chemistry and ocean chemical dynamics, which both focus on the same chemical phenomena in the ocean. Another synonym is oceanography, which is a broader term that encompasses all the physical, chemical, geological, and biological aspects of the ocean. Marine biogeochemistry is another related field that studies the interplay between biological and chemical processes in the ocean. All these fields aim to create a better understanding of the oceans and their impact on the planet's atmosphere, climate, and ecology.
