Field and laboratory comparisons of visual, photographic and photoelectric methods of measuring linear polarization of underwater light demonstrate that satisfactory agreement may be obtained between their results. While laboratory data match closely, several uncontrollable factors, especially changes in cloudiness, increase the variance of field measurements. Of the three, the photoelectric polarimeter lends itself best to the study of degree of polarization in the horizontal plane at various depths....
