Oceanography
Oceanography is the scientific study of the ocean and its components, including marine organisms, ocean currents, waves, and the physical and chemical properties of seawater. It encompasses various sub-disciplines, such as biological oceanography, which focuses on marine life; physical oceanography, which examines oceanic processes and phenomena; chemical oceanography, which studies the chemical composition and properties of seawater; and geological oceanography, which investigates the ocean floor and coastal geology. Oceanography plays a crucial role in understanding the Earth's climate system, marine ecosystems, and the effects of human activity on ocean health.
