What is described by the concept of neutral buoyancy?

The concept of neutral buoyancy is defined as the state in which a diver neither sinks nor floats, allowing them to achieve a balanced position in the water column. When a diver is in neutral buoyancy, their weight is equal to the weight of the water they displace, resulting in an effortless hover. This state is crucial for many diving activities, as it enables divers to maintain control of their position underwater while conserving energy, facilitating the observation of marine life, and conducting underwater tasks without unnecessary vertical movement.

Achieving neutral buoyancy involves careful balancing of a diver's body weight and buoyancy from their equipment, which contrasts with the idea of floating on the water’s surface or the specific adjustments of weights. Consequently, being able to maintain neutral buoyancy is fundamental for diver safety and comfort, as it enhances their overall underwater experience without the risk of ascending or descending unintentionally.
