What are the 3 main water masses in the Atlantic ocean?
The water masses in the upper layer originate from wintertime subduction and are defined as central waters. Below the upper layer, the intermediate layer consists of three main water masses: Antarctic Intermediate Water (AAIW), Subarctic Intermediate Water (SAIW) and Mediterranean Water (MW).
What is the coldest deepest densest water in the oceans?
The densest deep water mass is formed in the Weddell Sea of Antarctica, and becomes the Antarctic Bottom Water (AABW).
Which is colder the Atlantic or the Pacific?
Is the Atlantic Ocean warmer than the Pacific Ocean? 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.
What is the name of the worlds largest ocean?
The Pacific Ocean
The Pacific Ocean is the largest and deepest of the world ocean basins. Covering approximately 63 million square miles and containing more than half of the free water on Earth, the Pacific is by far the largest of the world’s ocean basins.
Why is the Atlantic ocean Brown?
As light bounces off and passes through water, it reflects the color blue back to our eyes, but microscopic algae and tiny sediments known as colored dissolved organic matter muddy the metaphorical waters and cause oceans to appear green, red, or brown.
Why is Hawaii water so blue?
The reason the ocean is blue is due to the absorption and scattering of light. The blue wavelengths of light are scattered, similar to the scattering of blue light in the sky but absorption is a much larger factor than scattering for the clear ocean water.
At what temperature would a human freeze instantly?
At 82 F (28 C) you can lose consciousness. Below 70 F (21 C), you are said to have profound hypothermia and death can occur, Sawka said.
