According to experts, exploring the oceans is more difficult than exploring the moon

According to News’s report, honorary ocean scientist at NASA Dr. Gene Feldman: “We have better maps of the Moon and Mars than our own planet.” used the phrase.

Though humans have explored the ocean’s surface for tens of thousands of years, they’ve only been able to map about 20 percent of the seafloor, according to 2022 data from the U.S. National Oceanic and Atmospheric Administration (NOAA).

According to the WHOI, 12 astronauts have so far spent a total of 300 hours on the lunar surface, while three astronauts have spent about three hours exploring the Mariana Trench, located in the western Pacific Ocean, known as the deepest point in the world.

The limited deep sea exploration by humans is due to the ocean being so dark and very cold there is almost no visibility, and huge levels of pressure are experienced the deeper you go.

Geologist Jamie Pringle, of Keele University in England, said in a statement: “Searching in the water is very difficult because the ocean floor is much rougher than on land.” made his decision.


According to the WHOI, deep ocean trenches can reach depths of 11,000 meters, while the deep ocean extends to 1,000 to 6,000 meters below the surface.

These sea grooves, called “Hadal”, are named after Hades, the god of the underworld in ancient Greek mythology. In the Hadal regions, where the sun’s rays do not reach, temperatures approach freezing.

In 1948, scientists first discovered signs of life at a depth of about 6,000 meters in the ocean, according to the institute.

According to NOAA data, the first video of a creature that can reach about 60 feet in length was recorded in 2012 in the deep sea off Japan.

Oceanographer Feldman pointed out that the door to a new world was opened in the 1970s when Robert Ballard discovered an entirely alien ecosystem with “giant worms and oysters”.

Noting that these discovered creatures seem to communicate and attract their prey, Feldman said that these creatures do not need sunlight to continue their lives, but instead use chemical energy from hydrothermal leaks and holes created by magma that rises from the ocean floor.


Feldman said humans have impulses like going up and going down, and only a small portion of the deep and middle ocean has been explored by humans and a very small portion of the ocean floor has been mapped.

Feldman noted that the reason for access to such limited information is largely due to cost, pointing out that ships equipped with sonar can incur very high costs and fuel costs alone can be as high as $40,000 per day.

Only 240,000 of the 2.2 million species believed to exist in the oceans have been identified by scientists, according to Ocean Census, an initiative to record and study marine life.

In contrast, Feldman argued that it is impossible to know for sure how many marine animals live in the oceans.


One of the submarines used for tourism purposes to show the wreckage of the Titanic, which crashed into the iceberg and caused the deaths of 1,514 people, disappeared into the Atlantic Ocean on June 19.

Those on the submarine are known to be British billionaire Hamish Harding, owner of Action Aviation, which operates in the aviation industry, Pakistani businessman Shahzada Davud and his son Süleyman Davud, founder and CEO of OceanGate, the owner of the Stockton submarine Rush. , and French submarine pilot Paul Henry Nargeolet.
