| Antarctic Ocean The waters, including ice shelves, that surround the continent of Antarctica, which comprise the southernmost parts of the Pacific, Atlantic and Indian oceans, and also the Ross, Amundsen, Bellingshausen and Weddell seas | Dienvidu okeāns |
| Arctic Ocean The smallest and most poorly studied of the oceans on earth. It covers an area of 14 million square km that is divided by three submarine ridges, i.e. the Alpha Ridge, the Lomonosov Ridge, and an extension of the mid-Atlantic ridge. It is also nearly landlocked, covered year-round by pack ice, and the third of its area is continental shelf | Ziemeļu Ledus okeāns |
| Indian Ocean A body of water between the continents of Africa, Antarctica, Asia and Australia including the Bay of Bengal in the east and the Arabian Sea (with the Red Sea, the Gulf of Aden and the Persian Gulf) in the west, and containing several islands and island chains, such as the Andaman, Nicobar and Seychelles | Indijas okeāns |
| North Atlantic Ocean The northern part of the Atlantic Ocean, extending northward from the equator to the Arctic Ocean | Atlantijas okeāna ziemeļu daļa |

| 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 | okeāna virsmas un gaisa mijiedarbības aspekti |
| ocean circulation Water current flow in a closed circular pattern within an ocean | okeāna cirkulācija |
| ocean current A net transport of ocean water along a definable path | okeāna straume |
| 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 | okeāna piesārņošana |
| ocean exploitation The utilization of the ocean for its food resources, mineral resources, and energy and water sources | okeāna izmantošana |
| ocean outfall The mouth or outlet of a river, drain, sewer or any other place at which drainage or wastewater is discharged into a body of oceanic water | ieteka okeānā |
| ocean temperature A measure, referenced to a standard value, of the heat or coldness in a body of oceanic water | okeāna temperatūra |
| South Atlantic Ocean An ocean south of the equator between the eastern coast of South America and the western coast of Africa that extends southward to the Antarctic continent, including the Drake Passage, South Sandwich Islands and Falkand Islands | Atlantijas okeāna dienvidu daļa |
| South Pacific Ocean An ocean south of the equator between Southeast Asia and Australia in the Eastern hemisphere and South America in the Western hemisphere, extending southward to the Antarctic region, including the Tasman and Coral seas and numerous islands, such as Galapagos, Solomon, Easter, Samoa, Fiji and Tonga islands, and also New Zealand and its islands | Klusā okeāna dienvidu daļa |
