# gsw_t_maxdensity_exact

`in-situ temperature of maximum density of seawater`

## USAGE:

`t_maxdensity_exact = gsw_t_maxdensity_exact(SA,p)`

## DESCRIPTION:

```Calculates the in-situ temperature of maximum density of seawater.
This function returns thein-situ temperature at which the density
of seawater is a maximum, at given Absolute Salinity, SA, and sea
pressure, p (in dbar). ```

## INPUT:

```SA =  Absolute Salinity                                         [ g/kg ]
p  =  sea pressure                                              [ dbar ]
( i.e. absolute pressure - 10.1325 dbar )```
`p may have dimensions 1x1 or Mx1 or 1xN or MxN, where SA is MxN.`

## OUTPUT:

```t_maxdensity_exact  =  in-situ temperature at which the density of
seawater is a maximum for given Absolute
Salinity and pressure.                 [ deg C ]```

## EXAMPLE:

```SA = [34.7118; 34.8915; 35.0256; 34.8472; 34.7366; 34.7324;]
p =  [     10;      50;     125;     250;     600;    1000;]```
`t_maxdensity_exact = gsw_t_maxdensity_exact(SA,p)`
`t_maxdensity_exact =`
