The Sea-water and its Physical and Chemical Properties 



of selective absorption and selective scattering and also of the interaction of these two 

 processes on the colour of the sea. These results are summarized in Fig. 35 which 

 shows a part of the colour triangle and the spectral curve. The absorption colour of 

 sea-water lies on a curve running from the white point and approaching concave
