According to the statistics of scientists, the ocean area accounts for 70% of the earth’s area, and only 5% of the ocean world has been explored by humans. Among them, the deepest part of the ocean-those trenches that are thousands of meters or even tens of thousands of meters deep, are mysterious areas that no one has ever set foot in.
In 2019, an explorer finally successfully dived into the deepest parts of the world’s oceans, conquered the last “dead spot” on the earth, and set off a wave of human deep-sea exploration. The explorer is an American-Victor Vescovo.
Victor Vescovo was born in Texas in 1966. He was smart and energetic since he was a child. He liked reading science fiction by Jules Verne very much, and fell in love with science and adventure. In the subsequent life experience, Vescovo systematically paved the way for his adventure career step by step. In college, Vescovo received a lot of degrees in economics and political science from Harvard Business School, Massachusetts Institute of Technology, and Stanford University. After leaving university, Veskovo joined the Navy as an officer, trained in survival skills in the wild, and learned to fly airplanes and submarines. While training himself in the military, Vescovo invested in bonds and stocks to amass a fortune of $1 billion.
By the age of 32, Veskovo had all the conditions to become an explorer-knowledge, skills and money. He started his adventure career in 1998. The initial goal of the expedition was to climb mountains. In just a few years, Vescovo has ascended the seven peaks of the world, including Mount Everest, and he trekked through the Antarctic and North Pole. For the expedition, Vescovo spared no effort to invest a lot of manpower and material resources. He stitched up more than 100 scars due to his injuries in distress. Efforts paid off. In 2018, Guinness World Records certified Vescovo to become the 63rd explorer in human history to complete the “Land Adventure Grand Slam”.
Challenge the “deep” in the ocean
Although he has traveled all over the continent, Vescovo also hopes to become “the first person in history to reach the deepest part of the Atlantic Ocean”, so he set a new challenge for himself-dive into the deepest part of the five oceans .
At the end of 2018, Veskovo officially began this challenge. For the first stop, Vescovo chose the Puerto Rico Trench in the North Atlantic. This trench is the deepest place in the Atlantic Ocean. Scientists have estimated that its deepest point is about 8,700 meters. In December 2018, Vescovo successfully dived into this trench to help scientists determine the precise depth of the trench-the deepest point of the trench is at 19 degrees 42 minutes 49 seconds north latitude and 67 degrees 18 minutes 39 seconds west longitude. The depth is 8376 meters. Veskovo became the first explorer to dive into the deepest part of the North Atlantic.
In February and April of 2019, Veskovo dived into the two deepest trenches in the South Atlantic and Indian Oceans respectively, with a dive depth of more than 7,000 meters, which was also the first time for humans to reach there. Next, Veskovo and his team came to the Pacific Ocean and began to challenge the limit of human diving depth. In May 2019, Vescovo dived to the Mariana Trench in the North Pacific 5 times, and one of them reached the “Challenger’s Abyss” in the trench (“Challenger’s Abyss” refers to the Mariana Trench with a depth of about 11,000 meters. It is the deepest place in the world’s ocean, where the pressure at that depth is 1100 times the pressure at sea level), and the dive depth reaches 10928 meters. This is the lowest point of the earth that all human explorers in history have reached, and Veskovo stayed there for 4 hours.
In August 2019, Westwalk completed the last two diving missions-he visited the wreck of the Titanic in the North Atlantic (about 4000 meters deep) and the “Molloy Abyss” (about 5000 meters deep) in the Arctic Ocean. ). Since then, Vescovo has become the first person to climb the highest points of all continents in the world and explore the deepest parts of the oceans of the earth, completing the “Global Adventure Grand Slam” for the first time.
Cool black technology submarine
Being able to reach the deepest part of the ocean, Vescovo relies on high-quality technology products, that is, the “Limit Factor” submersible.
The “extreme factor” submersible is a deep-sea diving equipment specially customized by Weswalker from the “Triton” (Greek, “Triton” is a Poseidon) company in Texas, weighing about 11.7 tons. From the appearance, the “extreme factor” is a sphere wrapped in an acrylic resin shell, but in fact, its interior contains a variety of cutting-edge technologies. Inside the acrylic resin is a spherical titanium alloy shell with a thickness of 90 mm and a diameter of 3 meters. This titanium alloy spherical shell uses advanced forging technology. It has no welding or defects and has excellent toughness. In places where the depth of the ocean reaches 10,000 meters, the pressure is nearly a thousand times that of sea level. The “limiting factor” can continuously adjust the shape of the shell during navigation to adapt to changes in deep sea pressure.
The titanium alloy spherical shell protects the “limit factor” cabin. The cabin can accommodate two passengers and is equipped with enough oxygen to support two people’s 96-hour life activities. The “limiting factor” is driven by electric energy, equipped with 12 high-performance lithium batteries, 10 electric thrusters, 4 wide-angle cameras and 10 20,000-lumen light-emitting diodes. In an emergency, in order to increase buoyancy, these accessories You can throw it away. In addition, “Limit Factor” is also equipped with a sonar system to measure the topographic structure of the bottom of the deep ocean.
Since the “extreme factor” is designed for the deep sea environment, Veskovo also needs to equip it with a transport ship. For each dive, Veskovo and his companions must first drive the transport ship to the sea where the trench is located, and then Veskovo will take the “limit factor” to dive vertically from the transport ship to below sea level. According to the “Triton” company, the “limit factor” dive speed can reach 5 kilometers per hour. After the success of the Veskovo expedition, the “Triton” company intends to commercialize the “extreme factor” and sell it to government agencies or other billionaires.
New discoveries in the depths of the trench
Compared to the excitement brought about by expeditions, scientific exploration is the most important driving force for Veskovo to challenge the limit, and he has obtained many new discoveries as he wished.
For example, in the Java Trench in the Indian Ocean, Veskovo saw a new creature. Its body looked like a jellyfish, but its body was gelatinous and looked different from other species. Biologists in the same field believed that this This organism may be a tunicate. For another example, in the Mariana Trench, Vescovo saw 4 new species resembling shrimp, as well as some rare beetles and pink lionfish. It is estimated that Veskovo has discovered more than 40 new species during several diving missions. Some biological and water samples have been sent to the laboratory for analysis by biologists.
Mapping the sea floor is also one of the scientific exploration tasks. Vescovo and fellow scientists have measured the salinity, temperature, circulation and depth of the deep sea area through the “extreme factor” submersible, and all data is shared with scientific research institutions , With a view to drawing a global seabed map in 2030. Veskovo joked that the first thing he needs to do after diving is to open Wikipedia and correct the wrong deep-sea information in Wikipedia. What worries Vescovo is that he found man-made plastic in a 10,000-meter deep trench, which shows that white pollution has spread to the deepest part of the earth and is worthy of vigilance.
Currently, Veskovo is recording all his discoveries into a scientific documentary-“Deep Sea Planet”, which is expected to meet with you soon. Veskovo hopes that more and more people will have the opportunity to explore the deep sea, because at the bottom of the ocean, there are still many things to be discovered by humans.
