The Pacific Ocean is the largest ocean in the world. It covers about 46% of the Earth's water surface and about one third of its total surface area, making it larger than all of the Earth's total land area.
It extends from the Arctic in the north to the Southern Ocean in the south and it is bounded by Asia and Australia in the east and North and South America in the west. It is also divided by the equator into the North Pacific and the South Pacific.
Area: 60,060,700 Sq. Mile (155,557,000 Sq. Km)
Average Depth: 13,215 ft (4,028 m)
Greatest Known Depth: 36,198 ft (11,033 m)
Place of Greatest Known Depth: Mariana Trench
The Atlantic Ocean is the second largest ocean in the world. It extends from the Arctic in the north to the Southern Ocean in the south and it is bounded by North and South America in the east and Europe and Africa in the west. It is also divided by the equator into the North Atlantic and the South Atlantic.
Icebergs are common from February to August in the Davis Strait, Denmark Strait and in the northwestern Atlantic. The Bermuda Triangle is situated in the Atlantic Ocean and it is believed to be the site of mysterious and unexplained shipping and aviation accidents.
Area: 29,637,900 Sq. Miles (76,762,000 Sq. Km)
Average Depth: 12,880 ft (3,926 m)
Greatest Known Depth: 30,246 ft (9,219 m)
Place of Greatest Known Depth: Puerto Rico Trench
The Indian Ocean is the third largest ocean in the world. It is bounded by Asia in the north, Africa in the west, Australia in the east and the Southern Ocean in the south.
North of the Equator there is a monsoon climate and cyclones sometimes strike the shores of the Arabian Sea and the Bay of Bengal. The Indian Ocean is the warmest ocean in the world and north of 20°S latitude the minimum surface temperature is 22°C (72°F). South of 40°S latitude, temperatures drop quickly.
Area: 26,469,500 Sq. Miles (68,556,000 Sq. Km)
Average Depth: 13,002 ft (3,963 m)
Greatest Known Depth: 24,460 ft (7,455 m)
Place of Greatest Known Depth: Sunda Trench
The Southern Ocean is the newest and fourth largest Ocean in the world. It is situated south of 60°S latitude and it encircles Antarctica. Water temperatures vary between -2° to 10°C (28 - 50°F). Icebergs can occur an any time of the year throughout the ocean and some may have drafts up to several hundred metres.
The Southern Ocean is also known as the Great Southern Ocean, Antarctic Ocean, South Polar ocean, and Austral Ocean.
Area: 7,848,300 Sq. Miles (20,327,000 Sq. Km)
Avge Depth: 13,100 - 16,400 ft (4,000 - 5,000 m)
Greatest Known Depth: 23,736 ft (7,235 m)
Place of Greatest Known Depth: South Sandwich Trench
The Arctic Ocean is the smallest and shallowest of the world's five oceans. It is almost completely surrounded by Eurasia and North America and it is mostly situated in the Arctic north polar region. It is contained within a polar climate characterized by persistent cold and relatively narrow annual temperature ranges. The Arctic Ocean is partly covered by sea ice throughout the year and almost completely in winter.
The temperature and salinity of the Arctic Ocean vary seasonally
as the ice cover melts and freezes. Its salinity is the lowest of the five major oceans due to low evaporation, heavy freshwater inflow from rivers and streams and the limited connection and outflow to surrounding oceanic waters with higher salinities.
