What does turbidity refer to in diving?

Turbidity refers to the clarity of water, specifically how clear or murky it is due to the presence of suspended particles like sediments, plankton, or organic matter. In diving, clear water allows for better visibility, which is crucial for safety and exploration. High turbidity can obscure vision, making it more difficult for divers to see underwater formations, marine life, and their surroundings. Understanding turbidity is essential for dive planning and ensuring that divers can navigate safely and enjoy their experience.

The other options relate to different physical properties of water. While temperature pertains to how warm or cold the water is, saltiness refers to the salinity or concentration of salts in the water. The movement of water currents describes the flow and direction of the water, which can affect diving conditions but is separate from the concept of water clarity.
