A time series of remote-sensed chlorophyll-a concentration in Northeast Asian Seas from 6 years of GOCI observation

Abstract

The ocean color represents characteristics of oceanic environmental parameters by light (from the sun) interactions with underwater constituents such as phytoplankton, inorganic suspended particles, detritus, and dissolved organic matter. Remotely sensing the oceanicenvironment using from visible to near infrared wavelengths at a satellite level has successfully extracted oceanic environmental information in a large spatial scale. General ocean color mission focuses on a monitoring of chlorophyll-a concentration that indicates an abundance of phytoplankton on the ocean.The Geostationary Ocean Color Imager (GOCI) has been operated by Korea Ocean Satellite Center at Korea Institute of Ocean Science and Technology since it launched in June 2010. A time series of chlorophyll-a concentration collected by GOCI has been archived and analyzed. It has shown a strong seasonal pattern controlled by vertical mixing and radiation for photosynthesis. Strict criteria for data quality have been applied to the data for the time series analysis. Since GOCIs expected life time is 7 years, the time series observation is possible until the mission completion.emotely sensing the oceanicenvironment using from visible to near infrared wavelengths at a satellite level has successfully extracted oceanic environmental information in a large spatial scale.
