Which Is The Biggest Ocean Atlantic Or Pacific

Which Is The Biggest Ocean Atlantic Or Pacific – The Pacific Ocean is the largest and deepest ocean on Earth, covering more than 155 million square kilometers (60 million square miles) and an average depth of 4,000 meters (13,000 feet).

, the Pacific Ocean, as the name suggests, was very calm, with the nearest land being more than 400 nautical miles away.

Which Is The Biggest Ocean Atlantic Or Pacific

Covering more than 30 percent of the Earth’s surface, the Pacific Ocean is the largest body of water on Earth. This ocean has a land area of ​​more than 155 million square kilometers (60 million square miles), more than the land area of ​​all the continents. In addition, it contains almost twice as much water as the Atlantic Ocean, which is the second largest body of water in the world.

Which Ocean Is The Deepest?

The Pacific Ocean is also the deepest body of water on Earth, with an average depth of about 4,000 meters (13,000 feet). The deepest point on Earth, called Challenger Deep, is more than 11,000 meters (36,000 feet) deep and is located in the Mariana Trench in the Pacific Ocean.

The Pacific Ocean, which accounts for more than half of the Earth’s external water supply, was named by the explorer Ferdinand Magellan in 1520. Magellan named the waters “Pacific” because the waters were calm at the time (“Pacific” means peace). Jodie L.

The Pacific Ocean is the deepest and largest ocean on Earth, covering a third of the Earth’s surface. The vast ocean can seem insurmountable. But from Antarctica in the south to the Arctic in the north, from Asia to Australia to the Americas, the fragile ecosystems of the Pacific are under threat.

It is mostly due to human activity. We systematically fell for the fish in the Pacific Ocean. We took it for granted. Debris was also found in the deepest place on Earth, the Mariana Trench, which is 11,000 meters below sea level.

The Pacific, like the rest of the ocean, is acidifying as we put more carbon dioxide into the atmosphere. This means that fish have lost their sense of sight and smell, and marine life is struggling to make their shells.

The World Oceans series begins with five profiles delving into trade networks in the Indian Ocean, plastic pollution in the Pacific, light and life in the Arctic, the Atlantic fisheries, and the impact of the Antarctic Ocean on the global climate.

Most of the oxygen we breathe comes from the oceans. They regulate the weather, provide food, and provide millions in income. They are places of fun and entertainment, comfort and spiritual connection. A healthy and active ocean therefore benefits us all. With a better understanding of the threats to our precious Pacific Ocean, we can begin a long journey to protect it.

The problem of marine plastic came to scientific knowledge in the 1960s when two scientists saw albatross carcasses washed up on the North West coast of the Hawaiian Islands in the North Pacific. Almost three out of four albatross chicks that died before leaving the nest had plastic in their stomachs.

Plastic debris ranging in size from nanometers to meters has now been found in all major marine habitats around the world. A small fraction of this accumulates in floating garbage, the largest of which is known in the Pacific Ocean.

Much of the land-based plastic waste ends up in the ocean in rivers. Just 20 rivers account for two-thirds of the plastic input to the world’s oceans, 10 of which flow into the North Pacific. For example, the Yangtze River in China, which flows through Shanghai, discharges about 1.5 million tons of waste into the Yellow Sea of ​​the Pacific Ocean every year.

Plastic waste in the ocean poses many threats to marine life. Animals can become entangled in debris, such as discarded fishing nets, and become injured or drown.

Some organisms, such as microscopic algae and vertebrates, can also ride on floating debris and travel long distances across the oceans. This means they can spread beyond their natural range and colonize other areas as alien species.

Of course, wildlife can be seriously injured by ingesting waste such as microplastics less than 5 millimeters in size. That plastic can touch the animal’s mouth or accumulate in the stomach. Animals often die slowly and painfully.

Seabirds in particular often mistake floating plastic for food. A 2019 study found that seabirds had a 20% chance of dying after eating one item, rising to 100% after eating 93 items.

Plastic is very durable and can travel long distances across the oceans. The tsunami that hit Japan in 2011 sent 5 million tons of debris into the Pacific Ocean. Some traveled across entire ocean basins, eventually reaching the coast of North America.

And since plastic floating in the open ocean is carried primarily by surface currents and winds, plastic debris accumulates on the beaches of the islands in its path. Kamilo Beach, located on the southeastern tip of Hawaii’s Big Island, is considered one of the worst beaches in the world for plastic pollution. Around 20 tons of waste are washed up on the beaches every year.

Also, on the uninhabited Henderson Island, part of the Pitcairn Islands in the South Pacific, 18 tonnes of plastic have been collected on a beach 2.5 kilometers long. Thousands of plastic bottles are produced every day.

Plastic waste can follow different destinies in the ocean: some sink, some are washed ashore, and some are carried to the surface by winds, gusts and waves.

About 1% of plastic waste accumulates in five “garbage sites” in the subtropical open ocean. They are caused by ocean circulation caused by changing winds and the Earth’s circulation.

The Pacific Ocean Has A Plastic Problem. Here’s The Bold Plan To Fix It

There are two garbage patches in the Pacific Ocean, one in the northern hemisphere and one in the southern hemisphere.

The northern agglomeration area is divided into an eastern patch between California and Hawaii and a western patch east of Japan.

First discovered by Captain Charles Moore in the early 2000s, this eastern area is the largest both in terms of size (about 1.6 million square kilometers) and the amount of plastic , therefore it is known as the Pacific Garbage Patch. In terms of weight, this waste can weigh more than 100 kilograms per square kilometer.

The South Pacific Garbage Belt is located off the coast of Valparaiso, Chile and extends westward. Low concentration compared to its large counterpart in the North East.

The Arctic Ocean Is Becoming More Like The Atlantic And Pacific, Studies Say

Discarded fishing nets account for approximately 45% of the total plastic load in the Great Pacific Patch. Debris from the 2011 Japanese tsunami was also a major contributor, accounting for 20% of the patches.

Over time, large pieces of plastic break down into microplastics. Microplastics make up only 8% of the total plastic waste in the Great Pacific Rim, but represent 94% of the estimated 1.8 trillion plastics there. High productivity can “fill” the water.

Around 15 million tonnes of plastic waste is estimated to enter the sea from beaches and rivers every year. This amount is expected to double by 2025 as rubber production continues to grow.

We must act quickly to stem the tide. This includes collecting and removing plastic and making plans to stop producing more plastic in the first place.

What Are The Five Oceans Of The World?

The largest and deepest ocean in the world, the Pacific Ocean supports the largest fisheries in the world. For thousands of years, people depended on these fish for food and livelihood.

But around the world, including the Pacific Ocean, fishing activities are reducing fish populations faster than they can recover. This overfishing is considered one of the most serious threats to the world’s oceans.

Humans remove approximately 80 million tons of wild fish from the ocean each year. In 2019, the world’s leading scientists said that of all the threats to marine biodiversity in the last 50 years, fish have caused the most damage. They report that 33% of fish are overfished, 60% are overfished, and only 7% are underfished.
