A smoothly varying and internally self-consistent set of tables of the index of refraction of seawater with respect to air are presented. The dependence of the index on salinity , temperature 0 to 30C, wavelength 400 to 700 nm and pressure 0 to 1100 kgsq cm gage has been fully covered. The relevant literature from prior to 1900 through the present has been extensively reviewed. Various comparisons between indices obtained from these sources and the tables presented have been performed suggesting an overall accuracy of the tabulated index values of about 0.00003 at atmospheric pressure and 0.0001 at higher pressures. The requirements necessary for obtaining salinity and specific gravity directly from measurements of the index of refraction, for oceanographic purposes have been examined.
