The Science Of Going Deep
Exploring the depths of the ocean through scuba diving is a thrilling adventure. But diving deep comes with its own set of rules. Let’s unravel the science of going deep under the sea and what every diver needs to know.
Understanding Pressure Underwater
As divers descend, the water above exerts more pressure on their bodies. This is measured in atmospheres (ATM).
At sea level, the pressure is 1 ATM, but it increases by 1 ATM with every 10 meters (33 feet) these divers go down. Divers must adapt to this pressure to avoid injury.
Add as many rows as needed
| Depth (meters) | Pressure (ATM) |
| 10 | 2 |
| 20 | 3 |
| 30 | 4 |
Nitrogen Absorption And Scuba Diving
Nitrogen absorption increases the deeper divers go. Breathing air under pressure causes more nitrogen to dissolve in the bloodstream. This isn’t a problem until divers begin to ascend, which is when decompression sickness, also known as the bends, can occur.
Understanding nitrogen absorption is essential:
- Dive within limits to manage absorption
- Follow dive tables or dive computers for safety
- Plan for decompression stops if needed
These stops allow nitrogen to gradually leave the body. Following the dive plan and respecting the science keeps divers safe while enjoying the underwater world.
