Oceanic means belonging to the open sea. Oceanic waters, an oceanic climate, oceanic crust.
In geology, oceanic crust is thinner, denser and much younger than continental crust — none of it is older than about two hundred million years, because it is constantly made at ridges and destroyed at trenches. An oceanic climate is mild and wet, which is Britain's. Figuratively, oceanic means vast: an oceanic silence. Note Oceania, the region.
