Water body optical absorption/attenuation coefficient characterizes absorption and attenuation of the water body to light, only with the material composition in water body
It is relevant, it is two big inherent optics properties of water body independent of the geometry of water body light field.Light passes through medium, a part of quilt
Absorb, another part deviates the former direction of propagation and scattered；The collective effect of absorption and scattering causes the decay of light.
The change of the absorption coefficient of light and light attenuation coefficient has close contact with water constituent.In addition to pure water, light
Absorption coefficient is contributed from the absorption of coloured dissolved organic matters (CDOM), phytoplankton (ph) and non-admissible solutions (NAP)；
Suspended particulate substance is the main source for causing light scattering, and light-decay characteristic is determined together with the optical absorption characteristics of different component
Variation characteristic.
(a, unit is m to the absorption coefficient of light of water body-1) a branch of directional light is defined as through a unlimited thin uniform dielectric, light

A (λ)=aw(λ)+ap(λ)+aCDOM(λ), (1)
Right formula represents the tribute of full sea water (w), total particulate (p) and coloured dissolved organic matters (CDOM) to absorption respectively
Offer, wherein total particulate absorb again can further decompose phytoplankton (ph), non-admissible solutions (NAP) absorption spectrum it
With that is,
ap(λ)=aph(λ)+aNAP(λ)
(b, unit is m to the light scattering coefficient of water body-1) a branch of directional light is defined as through a unlimited thin uniform dielectric, light
Scattered power (B) and dielectric thickness (⊿ r) ratio, i.e.,：
(c, unit is m to the light attenuation coefficient of water body-1) be water body absorption and scattering coefficienth sum, i.e.,：
C (λ)=a (λ)+b (λ)
In the prior art, for the measurement of water body light absorbs attenuation coefficient, usually using total reflection pipe or hypersorption pipe, need
Enter trip temperature, salt correction and scatter correction；Or use spectrophotometer.It is multiple all to there is measurement operation in both approaches
Miscellaneous, influence factor is more, the problems such as error is big.
