Oceanography

Oceanography is the study of the biological and physical properties of the world’s largest bodies of water, the oceans.

Oceanography is a branch of Earth science and geography that studies the oceans, including their physical and biological aspects, as well as the interactions between the oceans and the atmosphere, land, and other bodies of water. It involves the study of ocean currents, waves, tides, temperature, salinity, and other physical characteristics, as well as the diverse array of marine life that inhabits the world’s oceans.
