Obtaining Inherent Water Optical Properties From Apparent Water Optical Properties

Proceedings of SPIE, 1988
Modeling the radiative transfer in the ocean requires the volume absorption coefficient, a, and the volume scattering coefficient, b. These are generally not measured during ocean optical field experiments, rather one typically finds that the apparent optical properties are measured or at least derived from irradiance measurements.

Inherent and apparent optical properties of Lake Peipsi, Estonia

, 2004
Lake Peipsi on the border of Estonia and Russia is a large, shallow, biologically very productive lake. It is bordered by many wetland areas. On the basis of underwater radiation measurements and analyses of water samples we have shown that the optical properties of L.

Relationship Between Apparent Optical Properties and Photosynthetic Pigments in the Sub-Alpine Lake Iseo

Science of the Total Environment, 2001
The aim of the present study was the evaluation of methods for estimating the content of bio-physical parameters in lake water on the basis of spectral reflectance measured above water surface, in particular the estimation of chlorophyll-a (chl-a) concentrations. Data sets considered refer to some sampling point located in the sub-alpine meso-eutrophic

An Application of Transport Theory in Optical Oceanography: The Estimation of the Apparent Optical Properties Using Henyey-Greenstein Phase Function

Transport Theory and Statistical Physics, 2009
Transport theory methods can be applied to optical oceanography to solve forward and inverse problems. The combination of delta function representing forward and backward scattering with isotropic scattering is used to obtain scalar and plane irradiances for Henyey-Greenstein phase function.

The Effect of Nonuniform Vertical Profiles of Chlorophyll Concentration on Apparent Optical Properties

Proceedings of SPIE, 2008
The purpose of this research is to study the effect of nonuniform vertical profiles of chlorophyll concentration on apparent optical properties with Radiative transfer model Hydrolight. The vertical profiles of chlorophyll concentration were approximated according to a Gaussian function(Lewis et al, 1983).The simulated AOPs for nonuniform chlorophyll

Inherent and Apparent Optical Properties of the Complex Estuarine Waters of Tampa Bay: What Controls Light?

Estuarine, Coastal and Shelf Science, 2013
Abstract Inherent and apparent optical properties (IOPs and AOPs) of Tampa Bay (Florida, USA) were measured during fourteen cruises between February 1998 and October 2010 to understand how these properties relate to one another and what controls light absorption and diffuse attenuation in this moderately sized (∼1000 km2), shallow estuary (average ...

Unusual links between inherent and apparent optical properties in shallow lakes, the case of Taihu Lake

Hydrobiologia, 2011
The spectral distribution of downwelling solar irradiance is an important factor in the radiative balance, primary productivity and biogeochemistry in most lakes. In the present study, we show the relative importance of different inherent and apparent optical properties in controlling the spectral attenuation of diffuse downwelling irradiance in a ...

Altering apparent optical properties with an array of semitransparent mesoscale structures

Journal of the Optical Society of America A, 2022
The ability to control and optimize interactions between light and matter has much utility in engineering design. A well-researched way to achieve optical property modulation is via the use of optical metamaterials, which feature sub-wavelength scale surface structures.

Simulation of apparent optical properties in different seawater

Optical Review, 2015
In both optical oceanography (bio-optical) and biophotonics, one of the main objectives is to be able to simulate the propagation of light in heterogeneous turbid media. The most widely used approach is the Monte Carlo method which is a standard for its flexibility and reliability in modeling the geometry of a heterogeneous system.
