Optical Closure of Apparent Optical Properties in Coastal Waters off Goa
Journal of the Indian Society of Remote Sensing, 2014Inherent and apparent optical properties were measured for coastal waters off Goa, a site on the west coast of India using the in-situ measuring profiling optical instruments. The optical closure was obtained using the radiative transfer model, Hydrolight (Sequoia Inc.).

Absorption correction and phase function shape effects on the closure of apparent optical properties
Applied Optics, 2016We present a closure experiment between new inherent optical properties (IOPs: absorption a, scattering b, backscattering bb) and apparent optical properties (AOPs: remote-sensing reflectance Rrs, irradiance reflectance R, and anisotropic factor at nadir Qn) data of Ionian and Adriatic seawaters, from very clear to turbid waters, ranging across one ...

Optical property and apparent color of wild grape (Vitis coignetiea) extract
Food Science and Biotechnology, 2015The total anthocyanins extract was prepared from wild grape (Vitis coignetiea) as a feasible source of natural colorant. Amounts of total and several major individual anthocyanins were determined, and colors at various pH were determined. Total content of anthocyanins in wild grape was 1.1 % (w/w, wet basis).

Temporal variability in SeaWiFS derived apparent optical properties in European seas
Continental Shelf Research, 2010Abstract The 10-year record of ocean color data provided by the SeaWiFS mission is an important asset for monitoring and research activities conducted on the optically complex European seas. This study makes use of the SeaWiFS data set of normalized water leaving radiances L WN to study the major characteristics of temporal variability ...

Seasonal to multi-decadal trends in apparent optical properties in the Sargasso Sea
Deep Sea Research Part I: Oceanographic Research Papers, 2017Abstract Multi-decadal, monthly observations of optical and biogeochemical properties, made as part of the Bermuda Bio-Optics Project (BBOP) at the Bermuda Atlantic Time-series Study (BATS) site in the Sargasso Sea, allow for the examination of temporal trends in vertical light attenuation and their potential controls.

A method and algorithm of computing apparent optical properties of coastal sea waters
IGARSS '96. 1996 International Geoscience and Remote Sensing Symposium, 2002A new approach is proposed for the calculation of irradiances, diffuse attenuation coefficients and diffuse reflectances in waters with arbitrary scattering and absorption coefficients, arbitrary conditions of illumination and a bottom with Lambertian albedo.

Assessment of apparent and inherent optical properties derived from SeaWiFS with field data
Remote Sensing of Environment, 2005Abstract The knowledge of the absorption and scattering characteristics of the ocean supports diverse applications for studying biological and physical processes of marine ecosystems. The determination of the related inherent optical properties from remote sensing is addressed for a site located in the northern Adriatic Sea using coincident SeaWiFS ...

Spectral measurements of remote-sensing reflectance (Rrs) and absorption coefficients carried out in three European estuaries (Gironde and Loire in France, Tamar in the UK) are presented and analyzed. Typical Rrs and absorption spectra are compared with typical values measured in coastal waters. The respective contributions of the water constituents, i.

A stochastic approach is developed to resolve the scale variability between point and aerospace measurements in ocean color match-up sites. The model used the differences between in situ and aerospace-observed spectra and ocean color model inversion to estimate the subscale variability of apparent and inherent optical properties (IOPs).
