OCEANOGRAPHY: THE SCIENTIFIC STUDY OF EARTH’S OCEANS

Oceanography is an interdisciplinary scientific discipline that explores the physical, chemical, geological, and biological aspects of Earth’s oceans. Covering more than 70 % of the planet’s surface, oceans play a crucial role in regulating climate, supporting biodiversity, and providing essential ecosystem services. This article reviews the scope and major subdivisions of oceanography, highlights key oceanic processes, and discusses the importance of ocean research in addressing environmental challenges such as climate change, marine pollution, and sustainable resource use. Oceanographic knowledge is fundamental to understanding global environmental systems and informing policy and conservation efforts.
