Analytic model of ocean color

Applied Optics, 1997
Ocean color is determined by spectral variations in reflectance at the sea surface. In the analytic model presented here, reflectance at the sea surface is estimated with the quasi-single-scattering approximation that ignores transspectral processes. The analytic solutions we obtained are valid for a vertically homogeneous water column.

Ocean color monitor sensor

SPIE Proceedings, 2006
Costal Zone Color Scanner (CZCS) was the first of its kind sensor flown in 1978 for ocean studies. It gave quantitative estimate of phytoplankton. After that, many missions were launched by various agencies like IRS-P3-MOS, Sea-WiFS, OCTS, MODIS, MERIS etc.

Ocean color through satellite lidars: the COLOR project

2023
During the last decade, new applications exploiting data from satellite borne lidar measurements demonstrated that these sensors can give valuable information about ocean optical properties [1,2,3]. Within this framework, COLOR (CDOM-proxy retrieval from aeOLus ObseRvations) consisted in a 18-month feasibility study approved by ESA within the Aeolus ...

Ocean-color CCD imager

SPIE Proceedings, 1998
An Ocean Color CCD Imager (OCCI) has been developed. It has three bands with nominal spectral region 430nm-520nm, 580nm- 670nm and 760nm-860nm. It is composed of three separate subsystem, each for one band, which have the same structure and operate in push-broom mode with 1024-pixel linear array CCD detectors.

Ocean-color model incorporating transspectral processes

Applied Optics, 1998
Ocean color is determined by spectral variations in reflectance at the sea surface, which in turn result from both elastic and inelastic processes. We extend an elastic-scattering model of sea surface reflectance to deal with Raman scattering, which is an inelastic process.

Ocean Color Calculations

1981
A matrix operator method (Plass et al, 1973a, 1973b; Kattawar et al, 1980) has been developed which calculates accurately the radiance and irradiance based on an atmosphere-ocean model. The reflection and refraction of the radiation at the ocean surface is taken into account.

Extracting information from ocean color

2022
Products derived from remote sensing reflectances ($R_{rs}(\lambda)$), e.g. chlorophyll, phytoplankton carbon, euphotic depth, or particle size, are widely used in oceanography. Problematically, $R_{rs}(\lambda)$ may have fewer degrees of freedom (DoF) than measured wavebands or derived products.

The evolution of ocean color

SPIE Proceedings, 2008
Analog examples of what primeval oceans might have looked in the Precambrian are probably extant in various regions and at various size scales in present day oceans albeit they have not been sufficiently recognized and/or studied. The Eastern Boundary Current Ecosystems (EBCEs), with their characteristic high productivity-inducing coastal upwelling ...

Remote Sensing of Ocean Color

2012
The oceans cover over 70% of the earth’s surface and the life inhabiting the oceans play an important role in shaping the earth’s climate. Phytoplankton, the microscopic organisms in the surface ocean, are responsible for half of the photosynthesis on the planet.

From Cells to the Ocean: Satellite Ocean Color

1991
Variations in the color of the ocean as seen from space are principally due to variations in the concentration and optical properties of biogenic materials, dissolved and particulate, in the upper ocean. From 1978 to 1986 the NIMBUS-7 Coastal Zone Color Scanner observed these variations over the global ocean; the wealth of data that has resulted is ...
