To dive safely, scuba divers should administration their price of descent and ascent within the water and be able to keep a relentless depth in midwater. Ignoring completely different forces like water currents and swimming, the diver’s overall buoyancy determines whether or not they ascend or descend.

Water attenuates gentle by selective absorption. 23 24 Pure water preferentially absorbs crimson light, and to a lesser extent, yellow and inexperienced, so the colour that’s least absorbed is blue light. 25 Dissolved materials can also selectively soak up color in addition to the absorption by the water itself. In other words, as a diver goes deeper on a dive, more color is absorbed by the water, and in clean water the colour becomes blue with depth. Color imaginative and prescient can be affected by turbidity of the water which tends to reduce contrast. Synthetic light is helpful to offer light in the …
