Function gsw::volume::sound_speed

source · 
pub fn sound_speed(sa: f64, ct: f64, p: f64) -> Result<f64>
Expand description

Sound speed in seawater (75-term polynomial approximation)

Arguments

  • sa: Absolute Salinity [g kg-1]
  • ct: Conservative Temperature (ITS-90) [deg C]
  • p: sea pressure [dbar] (i.e. absolute pressure - 10.1325 dbar)

Returns

  • c: Sound speed [m s-1]

Notes

  • Pressure is implicitly converted to Pa to obtain speed in m s-1;
