This function is a simplified method of calculating the absorption of sound
in water proposed in Ainslie and McColm, 1998 and based on Francois and Garrison, 1982.
Usage
absorptionWater(f, pH = 8, t = 0, s = 35, z)
Value
The sound attenuation rate in dB/km
Arguments
f
The frequency of the sound source in kHz.
pH
The average acidity or pH of the water. Default is 8.
t
The average temperature of the water in Celsius. Default is 0.
s
The average salinity of the water in parts per thousand (ppt). Default is 35 ppt.
