The color of the ocean is calculated from a model that realistically takes into account the various types of scattering and absorption events that occur in both the atmosphere and ocean. Solar photons are followed through the atmosphere and into the ocean by a Monte Carlo technique. The reflection and refraction at the ocean surface are included in the

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.

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 ...

SPIE Proceedings, 2003
Remote sensing algorithms for retrieving estimates of oceanic constituent concentrations, such as chlorophyll concentration, require as input measurements of spectral water-leaving radiance. This measurement is typically obtained from space-based sensors such as SeaWiFS or MODIS.

Calibration of the ocean color and temperature scanner
IEEE Transactions on Geoscience and Remote Sensing, 1999Calibration results of the ocean color and temperature scanner (OCTS) on board the Advanced Earth Observing Satellite (ADEOS) are presented. The authors have evaluated the OCTS responses to internal calibration sources (i.e., lamps, electric voltages, and sunlight), natural targets (i.e., night data and uniform targets in the daytime), external ...

Applications of satellite ocean color products
2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017In this paper, we provide an overview of ocean color products derived from the Visible Infrared Imaging Radiometer Suite (VIIRS) onboard the Suomi National Polar-orbiting Partnership (SNPP), which was launched on October 28, 2011. VIIRS ocean color products include normalized water-leaving radiance spectra nL w (λ) at VIIRS five spectral bands ...

VIIRS ocean color research and applications
2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015In this paper, we provide evaluations and assessments of the Visible Infrared Imaging Radiometer Suite (VIIRS) ocean color products, including normalized water-leaving radiance spectra nL w (λ) at VIIRS five spectral bands, chlorophyll-a concentration (Chl-a), water diffuse attenuation coefficients at the wavelength of 490 nm, K d (490), and at the ...

Influence of oceanic whitecaps on atmospheric correction of ocean-color sensors
Applied Optics, 1994The effects of oceanic whitecaps on ocean-color imagery are simulated and inserted into the proposed Sea-Viewing Wide-Field-of-View Sensor (SeaWiFS) atmospheric-correction algorithm to understand its tolerance to error in the estimated whitecap contribution.

From Cells to the Ocean: Satellite Ocean Color
1991Variations 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 ...

Effects of Winds on Ocean Color
2006 IEEE International Symposium on Geoscience and Remote Sensing, 2006Previous studies suggested that winds would indirectly affect the remote sensing of ocean color. Moderately roughened sea enhances the probability of specular reflection of solar disk by randomly orientated wave facets. Whitecaps due to breaking waves increase the diffuse reflectance of sea surface and hence radiant energy received at a color sensor ...
