Abstract
The salinity and temperature dependence (the latter being significant mainly at lower frequencies) of the quantity A in Lieberman's equation α=βf2+(Af0f2)/(f02+f2) for sound absorption in the ocean bare been obtained by the use of data contained in publications by Kurtze and Tamm and by Wilson and Leonard. Using the values for pure water absorption βf2 and for the power relaxation frequency f0 used by Del Grosso, the predicted absorptions for various frequencies f agree with the careful measurements of Murphy, Garrison, and Potter made in Dabob Bay in 1958.
