| ocean current (A net transport of ocean water along a definable path) | التيار المحيطي | |
| ocean dumping (The process by which pollutants, including sewage, industrial waste, consumer waste, and agricultural and urban runoff are discharged into the world's oceans. These pollutants arise from a myriad of sources) | التخلص من النفايات في المحيط | |

| ocean-air interface (The sea and the atmosphere are fluids in contact with one another, but in different energy states - the liquid and the gaseous. The free surface boundary between them inhibits, but by no means totally prevents, exchange of mass and energy between the two. Almost all interchanges across this boundary occur most effectively when turbulent conditions prevail. A roughened sea surface, large differences in properties between the water and the air, or an unstable air column that facilitates the transport of air volumes from sea surface to high in the atmosphere. Both heat and water (vapor) tend to migrate across the boundary in the direction from sea to air. Heat is exchanged by three processes: radiation, conduction, and evaporation. The largest net exchange is through evaporation, the process of transferring water from sea to air by vaporization of the water) | نقطة التقاء ماء البحر بالهواء | |
