oceanography

/ˈoʊʃəˌnɑgrəfi/

/əʊʃənˈɒgrəfi/

Oceanography is the scientific study of the ocean. If you're interested in biology, physics, and sea creatures, you might want to study oceanography.

Another way to say oceanography is "marine science." Scientists who specialize in oceanography are called oceanographers, and they focus on specific aspects of the sea which might include the physics of waves and currents or the biology of marine animals and plants. The word oceanography was coined in the mid-1800s, modeled on geography, from ocean and -graphy, "the process of writing or recording."
