Table 5.2 Coefficients for the empirical shallow-water transmission loss formula: TL = 15 log10(R) + AR + B + CR2 (dB). Range (R) is measured in km, and the coefficients A, B and C are valid for a frequency of 200 Hz for the sound-speed profiles (A-H) illustrated in Figure 5.9 over a fine-sand bottom
