Oceans make up 71 percent of Earth and, according to NOAA’s National Geophysical Data Center estimates, consist of 321,003,271 cubic miles of water. With so much space to be explored, subsea technology experts, Tracerco, has attempted to establish just what can be found here:
Exploring methods of communication and trade
The underwater cables which have been laid along the ocean floors of Earth, which includes various subsea technologies, allow around 50 percent of all communications to occur between nations. Furthermore, over 90 percent of all trade between countries is performed by ships.
Exploring geographic wonders
The Ocean is home to Earth’s largest living structure. This is the Great Barrier Reef — it measures around 2,600km and is so huge that it can be spotted from the Moon.
The world’s longest mountain range is also found in the ocean. Named the Mid-Oceanic Ridge, this mountain chain stretches for more than 56,000km across and covers parts of the Atlantic Ocean, the Indian Ocean, and the Pacific Ocean. Meanwhile, Earth’s highest mountain in the ocean is the Mauna Kea. Found off the coast of Hawaii, the mountain rises to 10,203 meters (33,474 feet) from the ocean floor, with 4,170 meters (13,680 feet) viewable above sea level.
Across the ocean floor, the Mariana Trench is the deepest area currently known. Located in the western Pacific Ocean and to the east of the Mariana Islands, the deepest point found here measures at an estimated 11,000 meters — or 36,000 feet.The average depth of the Earth’s oceans is also 3,720 meters — or 12,200 feet.
Other geographic wonders to be found in the Earth’s oceans include brine pools and underwater volcanoes, where methane and mud explode from their tips instead of lava. These can all be discovered in the ocean close to the Gulf of Mexico. There are also underwater hot springs found across the Earth’s oceans, where water with temperatures of 650°F shootout — that’s hot enough to melt lead.
Exploring signs of life
Keeping on the theme of nature, the world’s oceans are already known to house hundreds of thousands of known species. However, claims by scientists state that many more forms of marine life are yet to be discovered. On top of this, there are 4,000 species of coral reef fish to be found too, which is close to a quarter of all of the world’s marine fish species. Just be aware that a milliliter of ocean water also contains close to 1 million bacteria and 10 million viruses.
Exploring artifacts, remnants, and treasure
An interesting stat to begin this section is that there are more artifacts and remnants in the world’s oceans than there are in all of the Earth’s museums combined. There is almost 20 million tons of gold within the Earth’s oceans too — if all which was suspended was mined, there would be enough to give each person on the planet around 9 pounds of gold.
Close to $60 billion in sunken treasure has also found its way onto the ocean floor. On top of all of this, scientists have predicted there is as much as 50 quadrillion tons of dissolved solids contained there too. Calcium salts, magnesium salts, potassium salts and sodium salts make up the bulk of this huge figure.
