How can environmental conditions impact visibility during night diving?

During night diving, environmental conditions play a crucial role in influencing visibility. Factors such as plankton blooms can significantly reduce clarity in the water. In situations where there is a high concentration of plankton, the water can become murky, making it difficult to see even short distances, which is particularly challenging for night diving. These blooms can happen due to nutrient influx or specific environmental conditions, and when present, they scatter light and create a cloudy effect in the water.

Understanding this concept is critical for divers, as it highlights the need to assess water conditions prior to diving and to adapt their plans for visibility challenges. Being aware of how various environmental factors interact can help divers make informed decisions and enhance safety during nighttime exploration.
