sea surface
Where waves break
The boundary between ocean and atmosphere—the top of the sea where water meets air.
Sea surface appears most often in technical and scientific contexts: sea surface temperature, sea surface height.
Satellite instruments measure the sea surface to track climate patterns, ocean currents, and weather systems.
