gsw_sound_speed_t_exact

sound speed

Contents

USAGE:

sound_speed_t_exact = gsw_sound_speed_t_exact(SA,t,p)

DESCRIPTION:

Calculates the speed of sound in seawater.
TEOS-10

INPUT:

SA   =  Absolute Salinity                                       [ g/kg ]
t    =  in-situ temperature (ITS-90)                           [ deg C ]
p    =  sea pressure                                            [ dbar ]
        ( i.e. absolute pressure - 10.1325 dbar )
SA & t need to have the same dimensions.
p may have dimensions 1x1 or Mx1 or 1xN or MxN, where SA & t are MxN.

OUTPUT:

sound_speed_t_exact  =  speed of sound in seawater               [ m/s ]

EXAMPLE:

SA = [34.7118; 34.8915; 35.0256; 34.8472; 34.7366; 34.7324;]
t =  [28.7856; 28.4329; 22.8103; 10.2600;  6.8863;  4.4036;]
p =  [     10;      50;     125;     250;     600;    1000;]
sound_speed_t_exact = gsw_sound_speed_t_exact(SA,t,p)
sound_speed_t_exact =
