About the Subject
Ocean is a field focused on the study of the world’s oceans, including their physical properties, ecosystems, resources, and role in the Earth system and global climate.
What to Study
Ocean-related study explores the marine environment from multiple scientific perspectives. Core areas typically include:
Physical Oceanography, which studies ocean currents, waves, and circulation.
Chemical Oceanography, which examines the composition and chemical processes of seawater.
Biological Oceanography (Marine Biology), which studies marine organisms and ecosystems.
Marine Geology, which focuses on the structure and processes of the ocean floor.
Ocean-Atmosphere Interaction, which examines how oceans influence weather and climate.
Coastal and Shelf Processes, which study coastal dynamics and environments.
Marine Resources, which focuses on sustainable use of ocean resources.
Ocean Observation and Technology, which uses instruments and remote sensing to study oceans.
