Light penetration water depth

Water with high concentrations of phytoplankton is green and darker for the same reason that dense tropical forests are: Images Article images 4. Notice the Rhine river plume at high discharge to deflect to the right as a result of Coriolis force. Water also absorbs UV, though not too well, so don't expect clouds nor swimming to protect you from sunburn. With this ability, they can actually navigate by the skylight polarization pattern, or detect otherwise transparent, or silvery-scaled prey by seeing its effect on the polarization of light.

Ocean Zones - Water Depth Vs. Light Penetration

Sign in Already have an account? I just wanted to post this, about the protective value of humus; but I'm curious about algae using UV. In polar oceans the water is constantly mixed, and warming of the surface waters is insufficient to allow a thermocline to form. This is why "acid rain", resulting from industrial emission of gases such as sulphur dioxide that dissolve in water to produce strong acids, has created such a problem in some areas of the World. Any atmospheric gases that are soluble in water will pass into water bodies during rainfall as we saw when describing acid rain. UV light penetrates pure water very well, but not sea water because it has lots of things in it- not least plankton, bacteria etc.

Ocean Colour in the Coastal Zone

We monitor light penetration to determine if it is sufficient to support phytoplankton photosynthesis. We welcome suggested improvements to any of our articles. When seawater volume is reduced to one-fifth of the original, evaporite precipitation commences in an orderly fashion, with the more insoluble components gypsum…. Light Penetration refers to the amount of sunlight that penetrates the water column and reaches various depths. Water molecules, dissolved salts, organic substances, and suspended particulates combine to cause the intensity of available solar radiation to decrease with depth.
