1. THE UNLUCKY DIVERS OF DEEP SEA
For recreational divers , it is generally recommended to stay within depth limits that minimize the risk of DCS and nitrogen narcosis . These limits vary based on the diver's training and certification level . The most common recreational diving limit is 40 meters (130 feet) for certified divers . Technical divers , who undergo additional training and use specialized equipment , may be able to dive deeper , but they must adhere to more stringent safety protocols . Now here are some explanations for DCS and nitrogen narcosis .
2. DECOMPRESSION SICKNESS (DCS) :
When a diver breathes compressed air underwater, the body absorbs nitrogen from the air . As the diver ascends, the pressure decreases , and the excess nitrogen forms bubbles in the tissues and bloodstream . If a diver ascends too quickly, these bubbles can cause symptoms ranging from mild joint pain and rashes to more severe neurological and cardiovascular issues . To mitigate the risk of DCS , divers must follow dive tables or computer algorithms that specify decompression stops during ascent .
3. NITROGEN NARCOSIS :
Nitrogen narcosis, also known as "raptures of the deep" or "the bends," is a reversible alteration of consciousness caused by the increased partial pressure of nitrogen at depth . It can affect divers at various depths but becomes more pronounced at greater depths . Symptoms may include euphoria , impaired judgment, confusion , and loss of motor skills . The effects of nitrogen narcosis can impair a diver's ability to make sound decisions and perform critical tasks underwater .
It is crucial for divers to receive proper training , understand their own limitations , and follow safe diving practices to ensure their well - being underwater . With specialized equipment and training , humans can dive much deeper than recreational diving limits . Technical divers , who undergo extensive training and use specialized gear , have the ability to reach greater depths . Here are some examples of deep dives achieved by experienced technical divers :
4. SCUBA DIVING :
5. SATURATION DIVING :
Saturation divers work on offshore oil rigs and other commercial underwater structures . They live in a pressurized environment for extended periods , typically up to several weeks , allowing them to work at great depths for prolonged durations . Saturation divers have reached depths of over 500 meters (1,640 feet) using diving bells or saturation diving systems .
6. THE SUBMERSIBLE - BATHYSCAPHE TRIESTE :
This incredible feat achieved by Jacques Piccard , a Swiss engineer and oceanographer and his colleague , US Navy Lieutenant Don Walsh . On January 23 , 1960 , they made history by becoming the first humans to dive into the Mariana Trench , the deepest point in the ocean . The vessel that took them on this extraordinary journey was the Bathyscaphe Trieste , a deep-diving submersible designed by Piccard's father , Auguste Piccard . The Trieste was a remarkable piece of engineering , consisting of a spherical pressure hull made of steel , surrounded by a flotation tank filled with gasoline . The submersible was equipped with ballast tanks , which allowed it to dive and ascend and a manipulator arm for collecting samples .

Let's dive deeper into the incredible adventure of Jacques Piccard and Don Walsh as they explored the Mariana Trench .
8. THE DIVE :
The Bathyscaphe Trieste was designed and built by Auguste Piccard , Jacques' father , in the 1950s . The submersible underwent several test dives in the Mediterranean Sea before being shipped to Guam , where it would embark on its historic journey . On the day of the dive, the Trieste was launched from the USS Lewis , a US Navy ship and began its descent into the Mariana Trench , which is located in the western Pacific Ocean. The dive took about 4 hours and 48 minutes, with the submersible reaching a depth of 35,787 feet (10,902 meters) in the Challenger Deep, the lowest point in the trench which is approximately 35,787 feet (10,902 meters) deep . Piccard and Walsh spent about 20 minutes at the bottom , collecting samples and conducting experiments .
9. THE DESCENT :
During the descent , Piccard and Walsh experienced intense pressure , with the water pressure outside the submersible reaching over 1,000 times the pressure at sea level . The temperature also dropped significantly , reaching near-freezing levels .
10. REACHING THE BOTTOM :
At 1:06 pm local time , the Trieste reached the bottom of the Challenger Deep . Piccard and Walsh spent about 20 minutes at the bottom , collecting samples and conducting experiments . They also took photographs and made observations of the unique marine life that exists in the extreme conditions of the deep sea .
11. THE ASCENT :
After completing their tasks at the bottom , Piccard and Walsh began their ascent , which took about 3 hours and 15 minutes . The submersible returned to the surface and the crew was greeted as heroes .
12. LEGACY :
The successful dive into the Mariana Trench marked a historic milestone in ocean exploration . It demonstrated the feasibility of deep-sea submersible operations and paved the way for future explorations of the ocean's deepest regions . The dive also provided valuable scientific insights into the extreme conditions found in the deep sea .
13. INTERESTING FACTS :
1. Pressure : The pressure at the bottom of the Challenger Deep is over 1,000 times the pressure at sea level .
2. Temperature : The temperature at the bottom of the trench is just a few degrees above freezing .
3. Darkness : The deep sea is characterized by total darkness , with no light penetrating from the surface .
4. Life : Despite the extreme conditions , the deep sea is home to unique and diverse marine life .
14. CONCLUSION :
The adventure of Jacques Piccard and Don Walsh as they explored the Mariana Trench is an inspiring example of human curiosity, ingenuity and exploration . Their historic dive paved the way for future generations of oceanographers , engineers and explorers and continues to captivate people around the world .

However , Piccard and Walsh's historic dive remains an unparalleled achievement in the history of ocean exploration .
16. LEGACY :
The Bathyscaphe Trieste's dive into the Mariana Trench has inspired generations of oceanographers , engineers and explorers . The submersible itself is now on display at the National Museum of the United States Navy in Washington , D.C. Jacques Piccard's achievement has also been recognized with numerous awards and honors , including the National Medal of Science .
17. TITAN SUBMERSIBLE :
A submarines used for tourist visits to the titanic wreckage has gone missing in the Atlantic on June 19 , 2023 . Oceangate's sub called the Titan was carrying a group of five tourists and had an oxygen supply of about 96 hours . An OceanGate spokesman has said "our entire focus is on the crew members in the submarine and their families , and are exploring and mobilizing all options to bring the crew back safely . " Authorities conducted a search and rescue mission along with USA and Canadian coast guards to locate the missing submarine and its passengers . Authorities did not know the cause of the disappearance and feared the prospect of a rescue to be bleak since the wreck sits 12,000 ft deep . The experience to be part of this deadly trap costs the modest amount of $250,000 PER PERSON . There were 5 people on board the submarine , including its creator, Stockton Rush . The objective of this journey is to descend to a depth of 3,800 meters to admire the rusty remains that were once part of the famous Titanic structure . There is no other submarine in the world that can reach that depth, and there is also no other OceanGate submarine (first red flag) . On Sunday , after 1 hour and 45 minutes of starting the journey , all communication was lost . They have not heard anything from them despite the rescue operation starting immediately after losing contact with Stockton Rush . The submarine was controlled with a Logitech gaming controller , like a PlayStation controller (second red flag) . There was no regulatory authority to verify and approve the safety of the submarine, and when someone questioned this issue , they were fired . Who the hell pays $250,000 to see through the submarine's screen a ship that sank in 1912? For God's sake , watch a documentary on YouTube and you'll see exactly the same thing . Why didn't the submarine have GPS? In the world where AirTag costs 35 euros , could not a similar technology have been integrated in the submersible ? Only a few millionaires pay so much to die in this way . James Cameron, the director of the 1997 Hollywood film Titanic , told the BBC that the crew that built the submersible that imploded with the loss of five lives "cut corners."
The Titan sub's parent company , OceanGate, "didn't get certified because they knew they wouldn't pass," according to the statement . I wouldn't have boarded that submarine , he declared . The Titanic wreck is 3,810m (12,500ft) down . When Cameron learned that the submarine had lost both its navigation and communication at the same time he immediately suspected a disaster . "I felt in my bones what had happened . For the sub's electronics to fail and its communication system to fail and its tracking transponder to fail simultaneously - sub's gone." In losing Titan , St John's mulls a familiar tragedy , He said that on Monday , when he heard the sub had gone missing, "I immediately got on the phone to some of my contacts in the deep submersible community.
"Within about an hour I had the following facts. They were on descent. They were at 3,500 metres (11,483ft), heading for the bottom at 3,800 metres.
"Their comms were lost, and navigation was lost - and I said instantly, you can't lose comms and navigation together without an extreme catastrophic event or high, highly energetic catastrophic event. And the first thing that popped to mind was an implosion.
All passengers on the Titan are believed to have died instantly in a catastrophic implosion deep underwater .
