The Ring of Fire coinciding with the edges of one of the world's main tectonic plates, (the Pacific Plate) contains over 450 volcanoes and is home to approximately 75% of the world's active volcanoes. As such, there is limited life in this ocean. Mariana Trench, Pacific 35,827 ft Puerto Rico Trench, Atlantic 30,246 ft Java Trench, Indian 24,460 ft Arctic Basin, Arctic 18,456 ft The India Ocean is known to be quite warm, which keeps the production of phytoplanktons low. A verdict by the International Hydrographic Organization in the spring of 2000 delimited a fifth world ocean - the Southern Ocean - from the southern portions of the Atlantic Ocean, Indian Ocean, and Pacific Ocean.
The U.S. is a member of the IHO, represented by the NOS Office of Coast Survey. All maps, graphics, flags, photos and original descriptions © 2020 worldatlas.com, The 5 Oceans of the World - Maps and Details. The Arctic Ocean lies to the north.
The boundaries of this ocean were proposed to the International Hydrographic Organization in 2000.
The Northwest Passage (US and Canada) and the Northern Sea Route (Norway and Russia) are two important seasonal waterways.
How to cite this article, National Oceanic and Atmospheric Administration. There are five oceans, separated by the continents (large areas of land), with the Atlantic, Pacific, and Indian Ocean linked in the south by the Southern Ocean. The Southern Ocean is the 'newest' named ocean basin. 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. This image of the Pacific Ocean seafloor and land elevations was created by the World Data Center for Geophysics & Marine Geology (Boulder, CO), National Geophysical Data Center, NOAA.
Their borders are indicated on the world image (above) in varied shades of blue. Types Of Oceans.
An ocean is a major body of Seawater (salt water)The Earth's oceans cover approximately 71% of the Earth's surface, 361,000,000 square kilometers (139,000,000 sq mi), and can be as deep as of 10,923 meters (6.787 mi). An ocean is a major body of Seawater (salt water)The Earth's oceans cover approximately 71% of the Earth's surface, 361,000,000 square kilometers (139,000,000 sq mi), and can be as deep as of 10,923 meters (6.787 mi) A biome is a large area with a distinctive climate, geology and oceanography.
Pacific Ocean which separate Asia from the Americas. Last updated: 04/09/20
Pacific (168,723,000 sq km) larger map; Atlantic (85,133,000 sq km) larger map; Indian (70,560,000 sq km) larger map; Southern (21,960,000 sq km) larger map; Arctic (15,558,000 sq km) larger map; Greatest Depths in the Ocean. The surface of the planet is approximately 71% water and contains (5) five oceans, including the Arctic, Atlantic, Indian, Pacific and Southern.
Each biome has its own unique biodiversity and subset of ecosystems. However, most countries - including the United States - now recognize the Southern (Antarctic) as the fifth ocean basin.
The boundaries of this ocean were proposed to the International Hydrographic Organization in 2000. Atlantic Ocean which separate the Americas from Europe and AfricaThe Atlantic Ocean is the second largest ocean in the worldThe Kiel Canal (Germany), Oresund (Denmark-Sweden), Bosporus (Turkey), Strait of Gibraltar (Morocco-Spain), and the Saint Lawrence Seaway (Canada-US) are main strategic access waterways. The Arctic Ocean is the smallest ocean in the world. Four critically important access waterways are the Suez Canal (Egypt), Bab el Mandeb (Djibouti-Yemen), Strait of Hormuz (Iran-Oman), and Strait of Malacca (Indonesia-Malaysia). Historically, there are four named ocean basins: the Atlantic, Pacific, Indian, and Arctic. Around 40% of the world’s offshore oil production is known to come from the Indian Ocean. The ocean is the largest of all the biomes on earth.
The Indian Ocean is the third largest ocean in the world. The Southern Ocean is the 'newest' named ocean basin.
It is recognized by the U.S. Board on Geographic Names as the body of water extending from the coast of Antarctica to the line of latitude at 60 degrees South. The large series of volcanoes (some active) encircling the Pacific Ocean are referred to as being part of the Ring of Fire, and notorious for frequent earthquakes and volcanic eruptions. The Southern Ocean extends from the coast of Antarctica north to 60 degrees south latitude, which concur with the Antarctic Treaty Limit. Within each ecosystem there are habitats or places in the ocean where plants and animals have adapted to survive.
The different bordering countries largely exploit the beach sands that contain a rich amount of heavy minerals.
The 5 Oceans by Size. To convert sq km (kilometers) to sq miles, multiply kilometers by: 0.386102; Surface Area of the Planet (510,066,000 sq km), Land Area on the Planet (148,647,000 sq km) 29.1%, Total Water Area (361,419,000 sq km) 70.9%.
Oceans are the largest areas of water in the world. For many years only (4) four oceans were officially recognized, and then in the spring of 2000, the International Hydrographic Organization established the Southern Ocean, and determined its limits. The boundaries between these regions have evolved over time for a variety of historical, cultural, geographical, and scientific reasons. Arctic Ocean which border the northern continents and encompasses the far North including the North pole.
However, not all countries agree on the proposed boundaries, so this has yet to be ratified by members of the IHO.
It is recognized by the U.S. Board on Geographic Names as the body of water extending from the coast of Antarctica to the line of latitude at 60 degrees South. The Pacific, Atlantic, and Indian are the most commonly known. It extends from Arctic in the north to Antarctica in the south, bounded by Americas in the east and Asia and Australia in the west.
Those limits include all water below 60 degrees south, and some of it, like the Arctic Ocean, is frozen.
Nearly 90% of the world's earthquakes occur along the Ring of Fire; most recently, the devastating quakes in Chile, Japan and New Zealand. Indian Ocean which separate India from Africa.
The Pacific Ocean is the biggest of the Earth's oceanic divisions. Author: NOAA
