In-water and remote measurements of ocean color
Boundary-Layer Meteorology, 1980Spectral measurements of downwelling irradiance, Ed(λ), above the surface, and of upwelling irradiance just below the surface, Eu(λ), allow computation of spectral values of the diffuse reflectance R(λ) = Eu(λ)/Ed(λ); this yields full information about the true color and brightness of the ocean.

Advances in radiometry for ocean color
SPIE Proceedings, 2003Organic materials in the oceans have spectral signatures based on their light-scattering properties. These optical properties are related to bio-physical and bio-chemical data products such as the concentration of phytoplankton chlorophyll-α through bio-optical algorithms.

Remote sensing of ocean color offers the potential of monitoring some of the characteristics of the upper layer of the ocean, on a global basis, by use of sensors on satellites or aircraft. Color sensing has been shown to be of use for parameters such as chlorophyll and sediment concentration and the location and motion of pollutants due to ocean ...

Ocean color through satellite lidars: the COLOR project
2023During 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 ...

Validation of the VIIRS ocean color
SPIE Proceedings, 2012The Joint Polar Satellite System (JPSS) launched the Suomi National Polar-Orbiting Partnership (NPP) satellite including the Visible Infrared Imager Radiometer Suite (VIIRS) on October 28, 2011 which has the capability to monitor ocean color properties.

Ocean color satellite of China
SPIE Proceedings, 1998The first Chinese Ocean Color Satellite (HaiYang-1) will be launched in 2000. The spacecraft will move and operate in a near sun-synchronous and near-polar orbit at altitude of 798 km. Installed on the satellite there are two sensors: one being 10 bands ocean color and temperature scanner with the spatial resolution of 1.1 km, the other being 4 bands ...

Satellite ocean-color observations of the tropical Pacific Ocean
Deep Sea Research Part II: Topical Studies in Oceanography, 2002The Coastal Zone Color Scanner (CZCS) data set provided some insights into biological processes in the equatorial Pacific, but the sampling was too sparse to address questions on temporal and spatial variability. Since late 1996, the Ocean Color–Temperature Sensor (OCTS), the Polarization Detection Environmental Radiometer (POLDER), the Sea-viewing ...

The next time you fly over the ocean, look out the airplane window and observe what is beneath you. The water will appear dark blue when flying over the clean, deep, open ocean; greenish when closer to shore; and yellowish or almost dark brown in color closer to cities, where the water becomes dirty.

Annual Periodicity in Ocean Color Observations Across Diverse Oceanic Regions
Applied OpticsThe annual periodicity present in spectral remote sensing reflectances (Rrs(λ)) derived from ocean color satellite data processed by NASA's Ocean Biology Processing Group has been shown to diverge from that observed in situ, with the source of the discrepancies remaining unresolved. Here we investigate such periodicity in reflectances derived from four

Colors of the ocean: Changes in the Anthropocene
MIT Science Policy ReviewChanges in the color of the ocean reflect how changes in Earth’s climate are transforming plankton ecosystems. Collecting data on both surface and underwater coloration is essential to monitoring the health of marine ecosystems across the ocean. Variations in ocean surface color, measured by satellites, hold information about the composition of ...
