MARINE BIOLOGY

Marine biology studies marine organisms, their behaviors, and their interactions with the environment. Marine biologists study biological oceanography and the associated chemical, physical, and geological oceanography fields to understand marine organisms.

MARINE ECOLOGY

Marine Ecology is the scientific study of marine-life habitats, populations, and interactions among organisms and the surrounding environment, including their abiotic (non-living physical and chemical factors that affect the ability of organisms to survive and reproduce) and biotic factors (living things or the materials that directly or indirectly affect an organism in its environment).

OCEANOGRAPHY

Oceanography is the interdisiciplinary study of the global oceans—from shallow coastal areas to the deepest ocean trenches, from the tropics to the polar seas. It’s typically divided into four sub-disciplines: physical oceanography (the study of waves, currents, tides, and ocean energy); geological oceanography (the study of the sediments, rocks, and structure of the seafloor and coastal margins); chemical oceanography (the study of the composition and properties of seawater); and biological oceanography (the study of marine organisms and their interactions with the ocean environment).
