Largest Ocean

What Is The Largest Ocean?

Most people are aware the largest ocean on this planet is the Pacific Ocean. The Pacific is the largest ocean by far, dwarfing the other two of the 3 large oceans, the Atlantic Ocean and the Indian Ocean. The other two oceans, smaller still, are the Southern Ocean and the Arctic Ocean. The Arctic Ocean is the smallest of our oceans, and because it mostly covered with ice most of the year, is the least traveled. The Southern Ocean, which encircles Antarctica, is less traveled than the other oceans as well. In fact, throughout most of recorded history virtually all ocean travel was restricted to the Pacific, Atlantic, and Indian Oceans.

Number One – By Quite A Bit - Just how big is our largest ocean? The Pacific Ocean covers just under 70 million square miles, just over one-third of the earth's total surface. It is nearly as large as the other four oceans combined. If you were in a spacecraft looking down on the earth and your location was directly above the island of Tahiti in the South Pacific, all you would see would be the Pacific Ocean. No land mass would be visible except for the islands in the South Pacific.

The Atlantic is the next largest ocean and covers just over 41 million square miles. Just over half the size of the Pacific, the Atlantic covers 20% of the earth's surface. The Indian Ocean is next, covering 29 million square miles, followed by the Southern Ocean and Arctic Ocean, covering 8 million and 5.5 million square miles, respectively.

The Pacific – The “Peaceful” Ocean  -In many ways the Atlantic may be considered the most interesting of the Oceans as it borders on some of the historically and geographically more well known seas, including the Mediterranean Sea, the Baltic Sea, Hudson Bay, the Caribbean Sea, and the Gulf of Mexico. It also has worse weather in many respects than the Pacific or Indian oceans, famed for its North Atlantic storms. The ocean with the worst weather however would have to be the Southern Ocean, graveyard of countless ships, with the area where the Southern, Atlantic and Pacific merge, off the southern tip of South America, being perhaps the most dangerous sailing waters in the world, or at least that was the case in the era of sailing ships.

Although the largest ocean waves could occur in any of the oceans, with the possible exception of the Arctic Ocean, and because of its size, the Pacific would seem to be the likely candidate for that sort of record, the largest recorded ocean wave on record, occurred in the North Atlantic, off the coast of Maine, and measured at close to 100 feet high. In terms of volumes of water, the Pacific tsunamis no doubt lead the pack.

Largest Ocean Animals - The largest animals in the world also inhabit our oceans. The largest animal of all is the Blue Whale, with the largest one ever recorded being 108 feet long with an estimated weight of 150 tons.  The Blue Whale is the largest ocean mammal, while the largest ocean fish is the Whale Shark, not nearly the size of the Blue whale but still measuring a respectful 40 feet in length. Neither of these monsters are to be feared, unless they surface under your boat, as they eat mostly krill and plankton.

There are many other largest ocean facts, including highest mountains, deepest canyons, and longest mountain ranges. Weirdest animal life could probably also be added to the list, at least weird in terms of appearance. Largest, smallest, heaviest, or strangest – you'll probably find it on one of our 5 oceans.
