Deepest Ocean in the World

The depths of the five oceans vary significantly from one another. So, which is the deepest ocean in the world? And what about the deepest part of the ocean? To delve more on these interesting topics, read on...

Mariana Trench Location (Click on the image for enlarged view)
According to geographical data, about 46% of the earth's water surface is contributed by Pacific ocean. In other words, it accounts to 30 percent of the earth's surface. An interesting pacific ocean fact is its volume, which is believed to be 622 million cubic kilometers. The Pacific ocean is divided into two parts (the north Pacific and south pacific) by the equator that passes through it. Various oceanography reports suggest the depth of Pacific Ocean to be 13,215 feet. The main reason for such a great depth is subduction of one oceanic plate under the other. As the two converging oceanic plates collided with each other, one of them moved downward, towards the mantle layer. This collision point lead to the formation of a trough, called the Mariana Trench. The Challenger Deep in the Mariana trench, the world's deepest oceanic part was explored by two hydronauts Don Walsh and Jacques Piccard as early as January 1960, by using a bathyscaphe named Trieste. Later in 2009, research of the Woods Hole Oceanographic Institution used Nereus robotic vehicle to reach a depth of 10,902 meters in the Challenger Deep region. Average Depth of Oceans
Pacific Ocean: 4,028 to 4,200 m • Atlantic Ocean: 3,300 to 3,600 m • Southern Ocean*: 4,000 to 5,000 m • Indian Ocean: 3,700 to 3,900 m • Arctic Ocean: 1,000 to 1,300 m
Every water body has a deepest part, as compared to other regions. The same is applicable to the five oceans of the world. Apart from the Mariana Trench, here is a list of the five oceans along with their deepest part. Deepest Part of Different Oceans
Pacific Ocean: 35,797 feet (Mariana Trench) • Atlantic Ocean: 28,374 feet (Puerto Rico Trench) • Southern Ocean*: 23,736 feet (South Sandwich Trench) • Indian Ocean: 23,376 feet (Java Trench) • Arctic Ocean: 17,881 feet (Eurasia Basin)
Oceans and seas make up the marine biome along with the estuaries, reefs, gulfs, and bays. Out of these, oceans are the largest ecosystems on earth, covering an area of about 335,258,000 sq km. Exploring the deepest part of the ocean is quite a challenging task for the scientists. Despite the tremendous advancements in science and technology, it is a fact that most parts of the ocean remain unexplored till date. The extremely high pressure, low temperature, and other inhospitable conditions make it challenging for humans to reach the deeper regions. Many times, unmanned robotic vehicles are used to collect images and study oceanic samples. Likewise, researches are ongoing to study and find more about the deepest part of the ocean and also, other inaccessible ocean regions.
