Etymology: Ocean is the older half of this word, and it carries a Greek myth with it. In Greek mythology, Ōkeanos was a great river encircling the flat earth, a boundary of the known world rather than a sea as we understand it. The Greek word passed into Latin as "Ōceanus," and from there through Old French into Middle English, where it came to mean the vast salt waters beyond the coast. The second half, "-ography," comes from the Greek "graphein," to write, which gave us a whole family of words for describing or recording things. "-graphia" meant a written description, and English adopted the suffix to name fields of systematic description, such as geography, the writing down of the earth. Oceanography follows the same pattern: a description of the ocean, built on a term that had originally pictured a river at the edge of the world.

Synonyms: marine science, ocean science
