SeaWiFS (Sea-Viewing Wide Field-of-View Sensor) was a satellite-borne sensor designed to collect global ocean biological data. Active from September 1997 to December 2010, its primary mission was to quantify chlorophyll produced by marine phytoplankton (microscopic plants).
Giovanni is a Web interface that allows users to analyze NASA's gridded data from various satellite and surface observations. Giovanni lets researchers examine data on atmospheric chemistry, atmospheric temperature, water vapor and clouds, atmospheric aerosols, precipitation, and ocean chlorophyll and surface temperature. The primary data ...
The processed data were archived at Goddard, and available to scientists worldwide. The data were originally stored on 38,000 nine track magnetic tapes, and later migrated to optical disc. The archive was one of the first instances of a system that provided a visual preview ("browse") of images, which assisted in ordering data.
Places where chlorophyll concentrations are high, meaning many phytoplankton were growing, are yellow. The observations come from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite. Land is dark gray, and places where MODIS could not collect data because of sea ice, polar darkness, or clouds are light gray.
Data are archived in the SeaBASS repository from field campaigns throughout the world, similar to the distribution of the ocean data shown in this example map. The SeaWiFS Bio-optical Archive and Storage System (SeaBASS) is a data archive of in situ oceanographic data used to support satellite remote sensing research of ocean color .
Satellite-derived chlorophyll-a concentration (mg m −3) from July 2002 to March 2017. This visualization was derived using data from the Moderate Resolution Imaging Spectroradiometer (MODIS) onboard NASA’s Aqua satellite. Chlorophyll-a concentration is a proxy for phytoplankton abundance. Darker shades of green indicate more chlorophyll and ...
Processing of Landsat 4 and 5 data was resumed by EOSAT in 1994. NASA finally launched Landsat 7 on 15 April 1999. ... was used to infer Chlorophyll, turbidity, and ...
Ocean optics research done “in situ” (from research vessels, small boats, or on docks and piers) supports research that uses satellite data. In situ optical measurements provide a way to: 1) calibrate satellite sensors when they are just beginning to collect data, 2) develop algorithms to derive products or variables like chlorophyll-a ...
