A new UV submersible spectroradiometer has been employed to determine the diffuse attenuation coefficient for irradiance in the clearest natural waters [K(w)(lambda)] with emphasis on the spectral region from 300 to 400 nm. K(w)(lambda) can be related to the inherent optical properties of pure water, in particular the total absorption coefficient a(w)(lambda) and the molecular scattering coefficient b(m)(lambda), by means of equations derived from radiative transfer theory. We present an…

Optical properties of the “clearest” natural waters

Optical measurements within both the visible and near ultraviolet (UV) parts of the spectrum (305–750 nm) were recently made in hyperoligotrophic waters in the South Pacific gyre (near Easter

Spectral Dependence Of The Diffuse Attenuation Coefficient Of Light In Ocean Waters

A study of the spectral nature of the diffuse attenuation coefficient of light, K (A), for various types of oceanic waters has been performed. These attenuation spectra were computed from downwelling

The author's experimental activities in ocean optics that are related to the inherent optical properties of natural waters are discussed and the first instrument to directly determine the backscattering coefficient b(b) is developed.

Raman scattering and in-water ocean optical properties.

The influence of Raman scattering, based on predictions of a modified two-stream model, is in agreement with measured values of spectral reflectance R( lambda,z) and the spectral diffuse attenuation coefficient for irradiance K(lambda,z).

Atmospheric correction of satellite ocean color imagery: the black pixel assumption.

The effects of nonzero NIR reflectance must be included in the correction of satellite ocean color imagery, particularly for turbid coastal waters.

Optical properties of pure water

The optical properties of pure water are basic input data for many geophysical investigations such as remote sensing of surface water and underwater radiative transfer calculations. Knowledge of the

Computed relationships between the inherent and apparent optical properties of a flat homogeneous ocean.

Monte Carlo simulations of the transfer of radiation in the ocean are used to compute the apparent optical properties of a flat homogeneous ocean as a function of the inherent optical properties and it is shown that these relations can be used with measurements of the upwelling and downwelling irradiance, the beam attenuation coefficient, and the incident radiance distribution.
