Abstract: An investigation is made into the determination of the relationship between the extinction coefficient and the salinity of sea ice. A HeNe laser is used to propagate a beam of red light, of wavelength 6328Å, through a series of ice samples at -20°C. The optical extinction coefficients were calculated and plotted against the measured salinities. The results of the experiment indicated an exponential relationship between extinction coefficient and salinity. The relationship may be described by the equation: 𝗒 = 𝟤.𝟦𝟣 + 𝟢.𝟢𝟢𝟣 𝖾𝗑𝗉 (𝟣.𝟣𝟫𝗑) where 𝗒 is the extinction coefficient and 𝗑 is the salinity.
