It is a quantity in ocean biogeochemistry and has many other applications including management of marine resources. It provides our only window into the marine ecosystem on synoptic scales. Of particular importance is the application to climate research: chlorophyll resides in phytoplankton, which use carbon dioxide in photosynthesis leading to a potential reduction in the atmospheric concentration of this greenhouse gas. In the climate context, it is vital that a seamless time series be constructed using data from all available missions. The merged data set protects the temporal continuity of the data stream and optimises the spatial coverage. }, title = {IOCCG Report Number 6, Ocean Color Data Merging}, url = {}, volume = {}, number = {}, journal = {}, pages = {}, issn = {}, publisher = {International Ocean-Colour Coordinating Group}, doi = {} }
