The study of the oceans is known as oceanography. It encompasses a wide range of topics such as marine life, ecosystems, currents, waves, the movement of sediments, and seafloor geology. Oceanography studies the physical, chemical, and biological characteristics of the ocean along with its history, current condition, and future. Concepts from numerous branches of science such as chemistry, geology, meteorology and biology are applied in oceanography. Some of the branches of oceanography are biological oceanography, chemical oceanography, geological oceanography, physical oceanography, and paleoceanography. This book attempts to understand the multiple branches that fall under the discipline of oceanography and how such concepts have practical applications. It aims to equip students and experts with the advanced topics and upcoming concepts in this area. This book will provide comprehensive knowledge to the readers.
