Introduction to Oceans
Oceans are the lifeblood of our planet. Not only do they cover more than 70% of the Earth’s surface and make up 97% of the planet’s water supply, they also provide food, energy, and recreation, as well generate oxygen and mediate the climate. Oceans are also a home to an astonishingly diverse range of plants and animals, which accounts for more than one-half of known species. They are a natural resource with substantial economic and scientific value.

The Concept of Oceans
Oceans are the large and diverse bodies of liquid water that cover much of the Earth’s surface. Oceans are divided into five main areas: the Arctic, the Antarctic, the Atlantic, the Pacific, and the Indian Ocean, with smaller regions such as the Mediterranean and the Caribbean Sea. There are several oceanic regions, such as the Atlantic Ridge, the Mid-Atlantic Ridge, the Oceanic Ridge, and the Polar Waters.

Oceans are continually being renewed. A 17th-century scientist, Sir Robert Boyle, described the process of ocean renewal as “the great sea-churn of nature,” because the deep waters at the bottom of the ocean are constantly being warmed by the heat of the Earth’s interior and pulled up to the surface, where they cool. This process, known as thermohaline circulation, is considered a major navigating force of ocean life, as it carries and replenishes food, nutrients, and oxygen to the marine life of the ocean.

Exploring the Oceans
Today, we are closer than ever to understanding and preserving the ocean’s resources, thanks to advances in technology and the dedication of people around the world who are passionate about the study and exploration of our oceans. From the depths of the trenches to shallow waters home to vibrant coral reefs and coastal ecosystems, there is an immense range of animal and plant life found in the ocean. Many scientists use subsea robots and unmanned aerial vehicles to collect data from deep waters, to supplement their efforts to monitor ocean health.

While the oceans can be an unpredictable and dangerous place, our fascination with the depths of the sea continues to draw us in. Could there be mysterious and unknown creatures living in the dark depths of the oceans? Could new and innovative technologies be developed that harness energy from the ocean? Only time will tell.

The exploration of the oceans is the key to the further development of human intelligence and the protection of our planet. If we continue to access the beauty and wealth of our oceans, along with the power and mystery that lies underneath, we can continue to explore and understand the mysteries of the deep blue sea.
