The largest of the Earth's seas is the South China Sea at around 3,500,000 square kilometres (1,400,000 square miles), and it borders China, Philippines, Malaysia, Brunei, Indonesia, Singapore and Vietnam.
The Philippine Sea is the largest in the world in terms of the surface area covered. It stretches 5.695 million square kilometres and lies in the western part of the North Pacific Ocean.
To summarize, while the body of water of the sea cannot be owned by anyone, the seabed is owned by the coastal State within the limits of the "territorial sea" and not beyond.
The South China Sea is a marginal sea south of China. It is a part of the Pacific Ocean, encompassing an area from Singapore to the Strait of Taiwan of around 3,500,000 km². It is the largest sea body after the five oceans.
Atlantic Ocean, Ocean separating North and South America from Europe and Africa. The second largest of the world's oceans, the Atlantic has an area of 31,830,000 sq mi (82,440,000 sq km).
The Indian Ocean is the third largest of the world's oceanic divisions, covering 70,560,000 km².
The Indian Ocean basin is the world's third-largest ocean with an area of about 70,560,000 square km (27,243,000 square mi). It covers almost 20% of the Earth's surface.
The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam. Challenger Deep is approximately 10,935 meters (35,876 feet) deep.
In the Pacific Ocean, somewhere between Guam and the Philippines, lies the Marianas Trench, also known as the Mariana Trench. At 35,814 feet below sea level, its bottom is called the Challenger Deep — the deepest point known on Earth.
In 1947, the Republic of China, the government of then China, announced the majority of the South China Sea was its territory. In 1949, the incoming government of China, which overthrew the Republic of China in the Chinese Civil War, announced that it had inherited this claim.
Australia has an Exclusive Economic Zone (EEZ) that extends beyond the 12 nautical mile territorial sea to a distance of 200 nautical miles (one nautical mile is internationally defined as 1.852 kilometres) in most places.
San Pedro Martir – Sea of Cortez is the richest body of water on our entire planet. The Island of San Pedro Mártir is located in the Gulf of California right in the limit between the Northern and Central Gulf Regions.
Every State has the right to establish the breadth of its territorial sea up to a limit not exceeding 12 nautical miles, measured from baselines determined in accordance with this Convention.
The Mariana Trench, in the Pacific Ocean, is the deepest location on Earth. According to the Exclusive Economic Zone (EEZ), the United States has jurisdiction over the trench and its resources. Scientists use a variety of technologies to overcome the challenges of deep-sea exploration and explore the Trench.
Looking at the entire oceans, however, the Pacific Ocean is by far the warmest overall ocean because it has about four times the intense sun-heated surface area in the tropics compared with the Atlantic Ocean.
Kazakhstan is the world's largest landlocked country while Ethiopia is the world's most populous landlocked country.
While the recommended maximum depth for conventional scuba diving is 130 feet, technical divers may work in the range of 170 feet to 350 feet, sometimes even deeper.
That means that most people can dive up to a maximum of 60 feet safely. For most swimmers, a depth of 20 feet (6.09 meters) is the most they will free dive. Experienced divers can safely dive to a depth of 40 feet (12.19 meters) when exploring underwater reefs.
The depth of the Mariana Trench makes it one of the deadliest places on the planet. Forever covered in darkness, water temperature is below 0 degree Celsius. What makes it near impossible for life as we know it to exist is the extreme water pressure. 8 tonnes per square inch increases with depth.
Geography. The Tasman Sea is 2,250 km (1,400 mi) wide and has an area of 2,300,000 km2 (890,000 sq mi). The maximum depth of the sea is 5,943 m (19,498 ft).
In terms of geography, seas are smaller than oceans and are usually located where the land and ocean meet. Typically, seas are partially enclosed by land. Seas are found on the margins of the ocean and are partially enclosed by land.
The Arctic Ocean is the smallest and shallowest of the world's five major oceans. This water body is completely surrounded by the continents of Asia, North America, Europe and the island of Greenland.
The Pacific is the largest, and arguably the most famous, of the world's oceans, though that isn't enough to make it the best.
Pacific Ocean
Besides being the biggest water body, the Pacific is also the oldest of the existing ocean basins. Its oldest rocks have been dated to about 200 million years ago, according to the National Oceanic and Atmospheric Administration (NOAA)'s National Ocean Service (NOS).
The Pacific Ocean is the largest and deepest of the world ocean basins. Covering approximately 63 million square miles and containing more than half of the free water on Earth, the Pacific is by far the largest of the world's ocean basins. All of the world's continents could fit into the Pacific basin.
