For much of recorded history, Earth was said to have four named oceans: the Atlantic, Pacific, Indian, and Arctic. However, many countries—including the United States —now recognize the Southern (Antarctic) Ocean as the fifth.
Oceans are thought to have formed in the Hadean eon and may have been the cause for the emergence of life. Plate tectonics, post-glacial rebound, and sea level rise continually change the coastline and structure of the world ocean.
Since the year 2000, the International Hydrographic Organization (IHO) started recognizing 5 oceans: Pacific, Atlantic, Indian, Arctic and Southern Ocean.
have divided it into five principal areas: the Pacific, Atlantic, Indian, Arctic, and Southern Oceans. The Atlantic, Indian, and Pacific Oceans merge into icy waters around Antarctica.
However, those conducting oceanic research generally recognize the existence of five major oceans: the Pacific, Atlantic, Indian, Southern, and Arctic oceans. Arbitrary boundaries separate these bodies of water, but they are largely defined by the continents that frame them.
Map of Earth's Five Oceans: Although there is only one global ocean, geographers have divided it into five major regions (which are also called "oceans"). They are: the Atlantic Ocean, the Pacific Ocean, the Indian Ocean, the Arctic Ocean and the Southern Ocean.
Oceans cover over 70% of Earth’s surface, making them the planet’s largest ecosystem. They hold about 97% of all water on Earth and are vital to life everywhere.
Oceans define our home planet, covering the majority of Earth’s surface and driving the water cycle that dominates our land and atmosphere.
The seven named oceans and many seas, bays, and estuaries, are all interdependent and connected as one global ocean. The importance of the ocean to our everyday lives is indisputable.

Roughly 71 percent of Earth’s surface is covered by saltwater oceans, and the continents themselves hold lakes, rivers, and, in some instances, seas. The largest bodies of water are the oceans, but there is some ongoing discussion regarding the actual number of separate oceans. So, how many does our planet truly have?
The terms "the ocean" or "the sea" used without specification refer to the interconnected body of salt water covering the majority of Earth's surface, i.e., the world ocean. [9][10] It includes the Pacific, Atlantic, Indian, Antarctic/Southern, and Arctic oceans. [20] As a general term, "the ocean" and "the sea" are often interchangeable. [21] Strictly speaking, a "sea" is a body of water ...
Are there 5 oceans? Are there 4 oceans? Or is there only 1 ocean? Water consumes 71% of Earth. Over time, the number of oceans has evolved from a single water body to something different. But it really depends on where you are from if you recognize that there is a fifth ocean. Pacific, Atlantic, Indian, Arctic… and the Southern Ocean which is off the coast of Antarctica. Today, we list the ...
Ocean, continuous body of salt water held in enormous basins on Earth’s surface. There is one ‘world ocean,’ but researchers often separate it into the Pacific, Atlantic, Indian, Southern, and Arctic oceans. Covering nearly 71 percent of Earth’s surface, the oceans have an average depth of 3,688 metres (12,100 feet).
Oceans, rivers, and streams have currents. The ocean’s salinity and temperature and the coast’s geographic features determine an ocean current’s behavior. Earth’s rotation and wind also influence ocean currents. Currents flowing near the surface transport heat from the tropics to the poles and move cooler water back toward the Equator .

They are: the Atlantic Ocean, the Pacific Ocean, the Indian Ocean, the Arctic Ocean and the Southern Ocean. These names facilitate communication.

How many oceans are there? There is only one global ocean. While there is only one global ocean, the vast body of water that covers 71 percent of the Earth is geographically divided into distinct named regions. The boundaries between these regions have evolved over time for a variety of historical, cultural, geographical, and scientific reasons.
The story of oceans is the story of life. Oceans define our home planet, covering the majority of Earth’s surface and driving the water cycle that dominates our land and atmosphere. But more profound still, the story of our oceans envelops our home in a far larger context that reaches deep into the universe and places us in a rich family of ocean worlds that span our solar system and beyond ...
