Evaluation of the Millard and Seaver [37
] model (MS) and the Quan and Fry [36
] model (QF) of refractive index of seawater using the datasets by Maykut and Light [42
] at subzero temperatures (a) and at salinities up to 121 g kg-1
(b) and by Daimon and Masumura [45
] and Irvine and Pollack [44
] at spectral range from 200 to 1100 nm (c). These datasets were not used in developing the MS and QF models and extend beyond the range of the original datasets used to develop these two models.
