The polar seas (high latitude) can be as cold as -2 degrees Celsius (28.4 degrees Fahrenheit) while the Persian Gulf (low latitude) can be as warm as 36 degrees Celsius (96.8 degrees Fahrenheit). Ocean water, with an average salinity of 35 psu, freezes at -1.94 degrees Celsius (28.5 degrees Fahrenheit).
What is the coldest ocean in the world?
The Arctic Ocean is the smallest, shallowest, and coldest part of the ocean.
How cold is deepest part of ocean?
Therefore, the deep ocean (below about 200 meters depth) is cold, with an average temperature of only 4°C (39°F). Cold water is also more dense, and as a result heavier, than warm water.
Which ocean is warmest?
The Indian Ocean has the warmest temperatures of the world’s oceans. Ocean water temperature is important to understand, as it affects global climate and marine ecosystems. The Indian Ocean is the warmest in the world.
Which ocean is very cold?
The coldest deep ocean water that flows around Antarctica in the Southern Ocean has been mysteriously disappearing at a high rate over the last few decades, scientists have found.
Which ocean is the most dangerous?
The South China Sea and East Indies, eastern Mediterranean, Black Sea, North Sea, and British Isles are the most dangerous seas in the world, with the greatest number of shipping accidents in the last 15 years, according to a report released by the World Wildlife Fund (WWF).
What is the youngest ocean?
The Atlantic Ocean is the world’s saltiest sea with a water salinity level of between 33 – 37 parts per thousand. It’s the world’s youngest ocean, formed long after the Pacific, Indian and Arctic Oceans of the Triassic Period.
How cold is it underwater?
The deep ocean is made up of horizontal layers of equal density. Much of this deep ocean water is between 0-3 degrees Celsius (32-37.5 degrees Fahrenheit)! It’s really, really cold down there! There is a neat program that is measuring the temperature and salinity of ocean surface waters around the world.
Is there ice at the bottom of the ocean?
while the bottom of the ocean is close to freezing, there is a unimaginable amount of pressure down there. and as everyone knows, when water freezes it expands. … Because of this, the coldest (frozen) water ice settles on the surface and the warmer liquid water (which is more dense) settles on the bottom.
What is the deepest sea on earth?
The average depth of the ocean is about 12,100 feet . The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam.
Which ocean is the cleanest?
Air over the Southern Ocean surrounding Antarctica is free from particles created by human activity, researchers say. Air over the Southern Ocean is the cleanest on Earth, scientists say.
What is the saltiest ocean?
Of the five ocean basins, the Atlantic Ocean is the saltiest. On average, there is a distinct decrease of salinity near the equator and at both poles, although for different reasons. Near the equator, the tropics receive the most rain on a consistent basis.

What are the 2 coldest oceans?
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.
Is deep ocean water salty?
Deep ocean water (DOW) is the name for cold, salty water found deep below the surface of Earth’s oceans. Ocean water differs in temperature and salinity. Warm surface water is generally saltier than the cooler deep or polar waters; in polar regions, the upper layers of ocean water are cold and fresh.
Which sea called warm water?
Warm water ‘blob’ cooks the Pacific Ocean, killing marine wildlife.
