The Antarctic region cooled down, and the ocean surrounding Antarctica began to freeze, sending cold water and ice floes north, reinforcing ...
The Southern Ocean, also known as the Antarctic Ocean, [1] [note 4] comprises the southernmost waters of the world ocean, generally taken to be south of 60° S latitude and encircling Antarctica. [5] With a size of 21,960,000 km 2 (8,480,000 sq mi), it is the second-smallest of the five principal oceanic divisions, smaller than the Pacific ...
The striking images, made from sonar readings, can help boats avoid dangerous obstacles in the poorly understood Southern Ocean. Hi-res images show the ocean floor around Antarctica in ...
The ocean contains 97% of Earth's water and is the primary component of Earth's hydrosphere and is thereby essential to life on Earth. The ocean influences climate and weather patterns, the carbon cycle, and the water cycle by acting as a huge heat reservoir. (Full article...) Waves in Pacifica, California.
