gsw_cndr_from_SP

conductivity ratio from Practical Salinity

Contents

USAGE:

R = gsw_cndr_from_SP(SP,t,p)

DESCRIPTION:

Calculates conductivity ratio (R) from (SP,t,p) using PSS-78.  Note that
the PSS-78 algorithm for Practical Salinity is only valid in the 
range 2 < SP < 42.

conductivity ratio from Practical Salinity.

INPUT:

SP  =  Practical Salinity  (PSS-78)                         [ unitless ]
t   =  in-situ temperature (ITS-90)                            [ deg C ]
p   =  sea pressure                                             [ dbar ]
       (ie. absolute pressure - 10.1325 dbar)
SP & t need to have the same dimensions.
p may have dimensions 1x1 or Mx1 or 1xN or MxN, where SP & t are MxN.

OUTPUT:

R   =  conductivity ratio                                   [ unitless ]

EXAMPLE:

SP = [34.5487; 34.7275; 34.8605; 34.6810; 34.5680; 34.5600;]
t =  [28.7856; 28.4329; 22.8103; 10.2600;  6.8863;  4.4036;]
p =  [     10;      50;     125;     250;     600;    1000;]
R = gsw_cndr_from_SP(SP,t,p)
R =
