The sun gives the sea its blue color which is otherwise colorless. The surface water absorbs all but the blue rays of the sun and reflects back the blue rays to give the impression that the water itself is blue.

The Atlantic Ocean, the second largest of the world's oceans, was named after the Greek Titan Atlas who held up pillars which supported the sky. These pillars, in Greek mythology, were thought to rest in the sea now called the Atlantic Ocean.

Sea water taken in large amounts can be fatal, but ice formed from salty sea water provides fresh drinking water after it is about a year old. The salt gradually disappears as the ice freezes, melts, freezes and melts again.

The Pacific Ocean, the largest on earth, is so vast it could hold all the water of the Atlantic, Indian and Artic Oceans and still not be filled.

In the past 100 years the world's seas have risen from six to eight inches.

The light of the sun cannot penetrate sea waters more than a half mile down.

An iceberg 208 miles long and 60 miles wide was observed in the South Pacific in 1956.

Antarctic ice is forced out over the Ross Sea, a large inlet into Antarctica, in a layer hundreds of feet thick. Called the Ross Ice Shelf, its area is about that of France.

The world's largest sea is the Mediterranean, yet even including its several arms (Aegean, Adriatic, Tyrrhenian, and Black Seas), it is less than one-fifth the size of the Antarctic Ocean. Other seas are the Caribbean Sea and the Bering Sea.

The Pacific Ocean fills nearly a complete hemisphere of the earth's surface.
