We consider the method for the determination of the colour index It (λ1, λ2) the wave lengths λ1 = 469 nm and λ2 = 555 nm from the data of the water leaving radiation obtained with the use of the colour space scanner MODIS/TERRA. The information on the colour index is used to calculate spatial distributions of the chlorophyll-a concentration, sea water colour and its transparency. The spatial structure and values of the chlorophyll-a concentration from the data of remote sensing are in good agreement with the results of synchronous contact measurements in the same area of the sea.
