The Arctic Ocean is the smallest and shallowest of the world's five major oceans. It spans an area of approximately 14,060,000 km2 (5,430,000 sq mi) and is known as one of the coldest of oceans.
The Arctic Ocean is the world's smallest ocean. It is also the shallowest out of the five major oceans of the world. It covers an area of about 5,430,000 sq mi (14,060,000 km2) and is the coldest out of all the other oceans.
Answer and Explanation: Y e s , the Arctic Ocean is the coldest ocean, even colder than the waters surrounding Antarctica. Since the Arctic ocean always has sea ice even during summer, the temperature of the surface is...
The Arctic is a frozen ocean surrounded by land. Antarctica, by contrast, is a frozen landmass surrounded by ocean. On a visit to either, your ship might bump through sea ice, but you would likely take more photographs of glacial ice because it's responsible for icebergs.

Although it might seem illogical, the Atlantic Ocean is warmer. For any given latitude, the Atlantic Ocean has proved to be about 16 degrees F (9 degrees C) warmer than the Pacific Ocean off the U.S. coast — quite a difference.
The Arctic Ocean is almost completely covered with ice for the majority of the year and its average temperature seldom rises above freezing.
The ocean does not freeze under extreme low temperatures due to the presence of salt, high volume, Earth's internal heat and ocean currents. Unlike rivers and lakes that freeze when the temperature drops to 0 degree celsius, the factors mentioned above prevent the ocean from freezing.
Fresh water freezes at 32 degrees Fahrenheit but seawater freezes at about 28.4 degrees Fahrenheit , because of the salt in it. When seawater freezes, however, the ice contains very little salt because only the water part freezes. It can be melted down to use as drinking water.
The high concentration of salt in ocean water lowers its freezing point from 32° F (0° C) to 28° F (-2° C). As a result, the ambient temperature must reach a lower point in order to freeze the ocean than to freeze freshwater lakes.
The Southern Ocean is the 'newest' named ocean.
The Arctic Ocean is found at the North Pole and Antarctica is found in the Southern Ocean at the South Pole. Antarctica is covered in ice and is the coldest place on earth.
The coldest water in the world is around Antarctica, the continent that covers the Earth's South Pole. Antarctica is covered by the Antarctic ice sheet, which is the largest mass of ice on Earth.
Arctic Ocean. The Arctic Ocean is the smallest and shallowest of the world's five major oceans. This water body is completely surrounded by the continents of Asia, North America, Europe and the island of Greenland.
But as in weather, where there are areas of high and low pressure, the ocean has areas of high and low salinity. Of the five ocean basins, the Atlantic Ocean is the saltiest. On average, there is a distinct decrease in salinity near the equator and at both poles, although for different reasons.
Arctic ocean swimming has long been practiced in Iceland but in recent years the trend has become increasingly popular with more people than ever taking a dip into the icy Atlantic Ocean.
Looking at the entire oceans, however, the Pacific Ocean is by far the warmest overall ocean because it has about four times the intense sun-heated surface area in the tropics compared with the Atlantic Ocean.
Because of the lake's extremely low elevation and sheltered location, winter temperatures are mild, averaging 63 °F (17 °C) in January at the southern end at Sedom and 58 °F (14 °C) at the northern end; freezing temperatures do not occur.
Geological evidence suggests the oceans may have frozen at least twice before. The last time was around 650 million years ago. Enough single-celled organisms survived that event to repopulate the Earth, but the fossil record isn't good enough to tell if there were other, multicellular life forms that weren't so lucky.
However, when water freezes in a lake or the ocean, the cold air is only above the water's surface. Below and to the sides, the water is still surrounded by more water or the by sea/lake floor, which are warmer than the air. Therefore, cooling, and thus freezing, can only happen from top down.
Boiling seawater does not make it safe to drink because it doesn't remove the salt. Freshwater on the other hand - say from a river - can be boiled to make it safe enough to drink.
Potential reasons why using seawater in cooking has not taken off here in America include health concerns, the foremost being excessive sodium consumption. Doctors have argued that adding seawater to dishes is reckless and promotes an unhealthy diet.
You can use sea water to cook octopus, to prepare risottos, stews, soups, broths, sauces, gravies, pickles and marinates, but only in dishes based on fish, mollusks and vegetables. It is quite useless to use it to cook meat and poultry, but you can always try if you want.
"During the great freezing," says Schrag, "carbon dioxide levels in the atmosphere dropped, the earth's temperature fell to around 58 degrees below zero, and the ice covered everything — ocean and land alike." Glaciers moved down from the mountains, dragging along rocks and the rubble that would be left behind when the ...
At a water temperature of 32.5 degrees, death may occur in under 15 - 45 minutes. At a water temperature of 32.5 to 40 degrees, death may occur in 30 - 90 minutes. At a water temperature of 40 to 50 degrees, death may occur in 1 - 3 hours.
In water that is around the freezing point, a person is likely to survive only 15 to 45 minutes with flotation and possibly up to an hour or so with flotation and protective gear before the brain and heart stop (Table 1).
