Inherent optical properties of Jerlov water types

摘要

The diffuse attenuation coefficient K-d(lambda) was first expressed in terms of the inherent optical properties (IOPs) of water according to well-established empirical bio-optical models. Boltzmann simulated annealing was then used to find the best sets of IOPs to fit K-d(lambda) spectra to the reference spectra K-d(0)(lambda) that define the Jerlov water types. Absorption a(lambda) and scattering b(lambda) coefficients were thus obtained for all Jerlov water types over the wavelength range 300 -700 nm. The chlorophyll concentrations corresponding to the Jerlov water types were also obtained via bio-optical models. The result is a self-consistent set of spectral IOPs, chlorophyll concentrations, and Jerlov water types useful for a variety of underwater optical communications and remote sensing applications.
