Oceans Oceans The Arctic Ocean, located mostly in the north polar region, is the smallest of the world's five oceans, and the shallowest. Even though IHO recognizes it as an ocean, oceanographers may call it the Arctic Mediterranean Sea or simply the Arctic Sea, classifying it as one of the mediterranean seas of the Atlantic Ocean. ...more on Wikipedia about "Arctic Ocean"
The Atlantic Ocean is Earth's second-largest ocean, covering approximately one-fifth of its surface. The ocean's name, derived from Greek mythology, means the " Sea of Atlas". ...more on Wikipedia about "Atlantic Ocean"
The Ekman spiral refers to a structure of currents or winds near a horizontal boundary in which the flow direction rotates as one moves away from the boundary. It derives its name from the Swedish oceanographer Vagn Ekman. The deflection of surface currents was first noticed ...more on Wikipedia about "Ekman spiral"
The Indian Ocean is the third-largest body of water in the world, covering about 20% of the Earth's water surface. It is bounded on the north by southern Asia (the Indian subcontinent); on the west by the Arabian Peninsula and Africa; on the east by the Malay Peninsula, the Sunda Islands, and Australia; and on the south by the Southern Ocean. It is separated from the Atlantic Ocean by the 20°east meridian south of Africa, and from the Pacific by the 147°east meridian. The northernmost extent of the Indian Ocean is approximately 30°north latitude in the Persian Gulf. This ocean is nearly 10,000 km (6,200 mi) wide at the southern tips of Africa and Australia; its area is 73,556,000 km² (28,400,000 mi²), including the Red Sea and the Persian Gulf. The ocean's volume is estimated to be 292,131,000 km³ (70,086,000 mi³). Small islands dot the continental rims. Island nations within the ocean are Madagascar (formerly Malagasy Republic), the world's fourth largest island; Comoros; Seychelles; Maldives; Mauritius; and Sri Lanka. Indonesia borders it. The ocean's importance as a transit route between Asia and Africa has made it a scene of conflict. Because of its size, however, no one nation had successfully dominated until the early 1800s when Britain controlled much of the surrounding land. ...more on Wikipedia about "Indian Ocean"
Ocean (from Okeanos, Greek for river, the ancient Greeks noticed that a strong current flowed off Gibraltar, and assumed it was a great river); covers almost three quarters (71%) of the surface of the Earth, and nearly half of the world's marine waters are over 3000 m deep. ...more on Wikipedia about "Ocean"

The Southern Ocean is the body of water encircling the continent of Antarctica according to some geographic and most hydrographic sources. It is the world's fourth largest ocean and the latest defined, having been accepted by a decision of the International Hydrographic Organization (IHO) in 2000, though the term has long been traditional among mariners. This change reflects the recent findings in oceanography of the importance of ocean currents. ...more on Wikipedia about "Southern Ocean"
