More broadly, the sea (with the definite article) is the interconnected system of Earth's salty, oceanic watersâconsidered as one global ocean or as several principal oceanic divisions.The sea moderates Earth's climate and has important roles in the water cycle, carbon cycle, and nitrogen cycle.alinity in the open ocean is generally in a narrow band around 3.5% by mass, although this can vary in more landlocked waters, near the mouths of large rivers, or at great depths. About 85% of the solids in the open sea are sodium chloride.
