# gsw_entropy_ice

**specific entropy of ice**

## Contents

## USAGE:

entropy_ice = gsw_entropy_ice(t,p)

## DESCRIPTION:

Calculates specific entropy of ice.

## INPUT:

t = in-situ temperature (ITS-90) [ deg C ]
p = sea pressure [ dbar ]
( i.e. absolute pressure - 10.1325 dbar )

p may have dimensions 1x1 or Mx1 or 1xN or MxN, where t is MxN.

## OUTPUT:

entropy_ice = specific entropy of ice [ J/(kg*K) ]

## EXAMPLE:

t = [-10.7856; -13.4329; -12.8103; -12.2600; -10.8863; -8.4036;]
p = [ 10; 50; 125; 250; 600; 1000;]

entropy_ice = gsw_entropy_ice(t,p)

entropy_ice =
