- 1. Oceanography is the study of the physical, chemical, biological, and geological aspects of the ocean. It examines the interactions between the ocean and the atmosphere, marine organisms, climate patterns, and the seafloor. Oceanographers use a variety of tools, including satellites, buoys, underwater vehicles, and computer models to research and understand the complex dynamics of the oceans. Through their work, they contribute valuable insights into marine ecosystems, ocean circulation, coastal processes, climate change, and more, helping us better comprehend and protect the vast and vital marine environments of our planet.
