Oceanographic → It is formed from "ocean" (from Greek "okeanos", meaning the great sea) and "-graphic" (from Greek "graphia", meaning writing or description). The word "oceanographic" refers to the description or study of the ocean.
Think of the word 'ocean' as the great sea and '-graphic' as describing something — so oceanographic means describing or studying the ocean.
