Oceans are responsible for the existence of life in our world. Life started in the ocean, and today, more than 230,000 marine species call the sea their home.
Oceans control the Earth’s climate and temperature. They balance heat and are crucial for the creation of rainfall.
On the occasion of World Oceans Day, on June 8, National Geographic officially declared the Southern Ocean (South Arctic Ocean) the 5th Ocean on Earth.
For the past century, National Geographic Magazine has been responsible for mapping the world’s oceans, and for the first time, it has mapped out a new part of the oceans.
