Abstract

The study of the chemical composition of seawater and sediments, as well as their interactions, is the primary focus of the oceanography subfield known as chemical oceanography. This interdisciplinary field consolidates information and methods from science, science, geography, and physical science to comprehend the complicated substance processes that happen in the sea. The ocean is a complicated system whose chemistry is crucial to the global carbon cycle, nutrient cycling, and marine ecosystem formation. The location, depth, and time of year all have an impact on the chemical composition of seawater. These variations are studied by chemical oceanographers to learn more about ocean circulation, biological productivity, and the effects of human activities on the marine environment.

The carbon cycle is one of the most important areas of chemical oceanography research. Carbon dioxide, which dissolves in seawater and reacts to produce carbonic acid, is a significant sink for carbon dioxide from the atmosphere. Ocean acidification is a process that has significant effects on marine ecosystems and life. Chemical oceanographers investigate the effects of ocean acidification on marine organisms as well as the rates and mechanisms of carbon dioxide uptake by the ocean.
