Functions

alpha_w	Calculate the fresh water attenuation in m-1.
correction_factor	Compute the part of the mean squared voltage independet of the sediment concentration: \(\frac{K_{\textup{s}} K_{\textup{t}}}{\psi r}^{2}e^{-4r\alpha_{\textup{w}}}\)
create_MSvoltage	Compute the mean squared voltage from a concentration profile, given a set of acoustic coefficients: \(\langle V^{2} \rangle = C \frac{K_{\textup{s}} K_{\textup{t}}}{\psi r}^{2}e^{-4r\alpha_{\textup{w}} - \int_{0}^{r}\xi C dr}\)
cumulative_trapezoid	Cumulatively integrate y(x) using the composite trapezoidal rule.
near_field_theoretical	Return the near field function.
sound_velocity	Compute sound velocity in fresh water in [m/s]
