Landsat MSS data off Cochin Coast was analysed ond on attempt made to look in to the relationship between
MSS gray values and concentration of pigment/particulate matter. MSS band 4 and 5 showed the maximum gray
value range as compared to band 6 and 7. A density sliced image of band 4 was generated in the form of
Q color coded image showing the gray levels corresponding to various pigment levels
