Inferring inherent optical properties and water constituent profiles from apparent optical properties [PDF]

open access: yesOptics Express, 2015
The BP09 experiment conducted by the Centre for Maritime Research and Experimentation in the Ligurian Sea in March 2009 provided paired vertical profiles of nadir-viewing radiances L(u)(z) and downward irradiances E(d)(z) and inherent optical properties (IOPs, absorption, scattering and backscattering coefficients).

Characterization of the Light Field and Apparent Optical Properties in the Ocean Euphotic Layer Based on Hyperspectral Measurements of Irradiance Quartet

open access: yesApplied Sciences, 2018
Although the light fields and apparent optical properties (AOPs) within the ocean euphotic layer have been studied for many decades through extensive measurements and theoretical modeling, there is virtually a lack of simultaneous high spectral ...

Transient optical properties of highly excited dielectric materials: Apparent birefringence and delayed reflectivity increase

open access: yesPhysical Review Research, 2020
The ultrafast dynamics of short-pulse-laser-excited fused silica is investigated by measuring polarization-resolved reflectances of a wavelength-tunable probe pulse following a near-infrared pump pulse.

Apparent optical properties of the Canadian Beaufort Sea – Part 1: Observational overview and water column relationships [PDF]

open access: yesBiogeosciences, 2013
A data set of radiometric measurements collected in the Beaufort Sea (Canadian Arctic) in August 2009 (Malina project) is analyzed in order to describe apparent optical properties (AOPs) in this sea, which has been subject to dramatic environmental ...

Dependence of relationship between inherent and apparent optical properties of water on solar altitude [PDF]

open access: yesLimnology and Oceanography, 1984
A computer simulation study, using the Monte Carlo calculation procedure, has been carried out to determine in what way the relationships between the apparent and the inherent optical properties of natural waters are affected by the angle of incidence of the photons on the surface. With the particular normalized volume scattering function used in these

Radiometry on Argo Floats: From the Multispectral State-of-the-Art on the Step to Hyperspectral Technology

open access: yesFrontiers in Marine Science, 2021
Over the past two decades, robotic technology such as Argo floats have revolutionized operational autonomous measurement of the oceans. Recently, Biogeochemical Argo floats (BGC-Argo floats) have measured optical and biogeochemical quantities down to a ...

Impact of Thermohaline Conditions on Vertical Variability of Optical Properties in the Gulf of Finland (Baltic Sea): Implications for Water Quality Remote Sensing

open access: yesFrontiers in Marine Science, 2021
Vertical variability of inherent optical properties (IOPs) affect the water quality retrievals from remote sensing data. Here, we studied the vertical variability of IOPs and simulated apparent optical properties (AOPs) in the Gulf of Finland (Baltic Sea)

High Resolution Water Column Phytoplankton Composition Across the Atlantic Ocean From Ship-Towed Vertical Undulating Radiometry

open access: yesFrontiers in Marine Science, 2020
Different phytoplankton groups dominate ocean biomes and they drive differently the marine food web and the biogeochemical cycles. However, their distribution over most parts of the global ocean remains uncertain due to limitations in the sampling ...
