The deepest point in the Pacific Ocean is the Challenger Deep in the Mariana Trench (10,929 m) located in the western North Pacific.â¨. A large number of highly polluted rivers from the countries of southeast Asia and east Asia drain into this ocean, contaminating the waters with pollutants. The Pacific Ocean is also home to the Mariana Trench, which is the deepest part of the ocean. In part because of the numerous tropical islands of East Asia, the Pacific boasts the longest total shoreline, some 84,300 miles (135,663 km). The Indian Ocean occupies 70,560,000 square km area on the Earthâs surface. ISSN: 2639-1538 (online).

Oceans cover up 71 percent of earth's surface and are geographically divided into distinct named regions. You see, there is only one global ocean on the planet. The ocean covers about 71% of the surface of the Earth. We cover everything from solar power cell technology to climate change to cancer research. saltiness comes from evaporation, precipitation, and water flows, DMMS: Efficient Diffeomorphic Metric Image Registration Via Stationary Velocity, Automatic Measurements Of Contact Angle And Curvature In Pore-Space Images, Science Can Now Make Wood Just As Strong As Steel, Free-Living Amoebae â A Novel Waterborne Risk Pathway That Now Includes Enteric Viruses.

However, today we recognize 5 oceans in the world, with the Southern Ocean added to the list. The surface of the planet is approximately 71% water and contains (5) five oceans, including the Arctic, Atlantic, Indian, Pacific and Southern. However, in the relatively shallow waters off the coast of Australia and New Zealand, petroleum and natural gas deposits have been discovered. Approximately, 80% of the ocean hasn't been mapped or explored. It covers 71 percent of the Earth’s surface. As we continue to explore and learn about the ocean, it becomes important to understand how it is defined by the world and what features it has that are crucial to the stability of the world. The melting would also result in the death of numerous species, including polar bears because they would lose their habitats. Using this method there are 5 oceans.

It is estimated that by 2040, the majority of the ice (if not all) will be melted because of global warming. The depth in this region is 8,047 m. The Indian Ocean region experiences a monsoon type of climate. The unique ecology and features of this region are sufficient enough, by IHO standards, to give it its own classification.
