Explain why sea divers can not dive beyond 600 meters from the surface of the sea

Decompression sickness

Nitrogen narcosis

Rapid air consumption

Explanation:

Sea divers can not dive beyond 600 meters from the surface of the sea because of the following :

Decompression sickness

Nitrogen narcosis

Rapid air consumption.

Deep Diving is any dive that is deeper than 20 meters which is 60 feet. However, we there are diverse kinds of diving which gives deep diving its own distinct definition.

In Recreational diving, the maximum depth limit to go is 40 meters which is equivalent to 130 feet

In technical diving, any dive deeper than 60 meters which is equivalent to 200 feet is known as a deep dive.

Decompression sickness : When a diver dive, the air breathe composed of oxygen, nitrogen and other gases. The body uses the oxygen but nitrogen is subsequently released over time since our body does not usually need it. So when pressure suddenly decline or drops, the nitrogen gas which is in the body expands and develops into bubbles. These bubbles are mostly trapped in the joints causing severe pain which is called decompression sickness.

Nitrogen narcosis is experienced when you accumulate too much of nitrogen. The first sign are tingling of the fingers, dizziness and disorientation. It also affects the sight by experiencing a tunnel vision this caused difficulties in reading gauges and instruments. The deeper you dive, the greater the effect of nitrogen narcosis experienced.

Rapid air consumption : The air breathe will become denser as you go deeper due to increasing pressure. Which will subsequently leads to consumption of more air while deep diving as compared to diving at shallower depths
