Abstract

Chemical oceanography is a multidisciplinary field that investigates the chemical processes and interactions occurring in the Earth's oceans. This branch of oceanography encompasses the study of the composition, distribution, and transformation of chemical elements, compounds, and isotopes in marine environments. Chemical oceanographers utilize various analytical techniques to quantify and trace the sources, sinks, and fluxes of substances in the oceans, including nutrients, trace metals, organic matter, pollutants, and greenhouse gases. By examining the chemical properties of seawater and sediment, chemical oceanography provides insights into fundamental processes such as ocean circulation, biogeochemical cycles, ocean acidification, and the impact of human activities on marine ecosystems. This abstract provides an overview of the key concepts and research areas in chemical oceanography, highlighting the significance of this field in advancing our understanding of the Earth's oceans.
