The Titanic, a grand symbol of wealth and advanced technology, lies deep beneath the ocean, having sunk over a thousand years ago. Despite the passage of decades, the wreck remains intact. Why is this the case? Join us as we explore and gain a comprehensive understanding of this intriguing phenomenon.
1 Why Wasn’t the Titanic’s Wreck Crushed at the Ocean’s Depths?
The simple answer is that the Titanic was a faulty, non-watertight object, and as it sank, water entered its interior, preventing any pressure differential from occurring. This is similar to how divers’ suits can withstand depths of up to 11,000 meters in the Mariana Trench without being destroyed or disintegrating.
In contrast, the Titan submersible had a sealed, hollow structure, resulting in a significant pressure differential between the inside and outside, leading to its crushing at ocean depths.

2 What Is the Pressure Differential Like at the Ocean’s Depths?
The pressure differential at the ocean’s depths refers to the difference in water pressure at a certain depth below the sea and the air pressure at ground level. Water pressure increases linearly as we dive deeper into the sea. For every 10 meters we descend, the pressure increases by 1atm, meaning each square centimeter experiences an additional kilogram of pressure.
When divers descend to a depth of 30 meters, their bodies endure a pressure of up to 45,000 kilograms. However, the human body has a pressure-balancing mechanism, as our bodies are mostly water (about 60%), and the inhaled air creates pressure equal to that of the surrounding water. This balance counteracts the crushing force of the deep ocean.

4 How Can Fish Tolerate High Pressure?
Fish have a unique circulatory system that can withstand high pressure and deliver oxygen to vital organs. They possess strong hearts and efficient blood-pumping capabilities, even under high pressure. Some species can even regulate their circulatory system and blood pressure to adapt to different depths.
Moreover, fish have a gas bladder system that pumps gas into fat or air bladders to increase their body pressure and maintain equilibrium. Their body structure is also well-suited for deep diving, with a streamlined shape, large gills, and the ability to regulate gill pressure to maintain stability in the water.
