Can humans survive 47 meters underwater?

According to the US Navy dive decompression tables a diver may spend up to five minutes at 160′ (47 meters) without needing to decompress during their ascent. The longer a diver stays underwater the greater their exposure to “the bends” becomes. … The bubbles can cause the bends.

Can a human dive to the Titanic?

How deep underwater can humans go without equipment?

For most swimmers, a depth of 20 feet (6.09 metres) is the most they will free dive. Experienced divers can safely dive to a depth of 40 feet (12.19 metres) when exploring underwater reefs. When free diving the body goes through several changes to help with acclimatisation.

Why is chumming the water illegal?
