gsw_spiciness1

`spiciness at p = 1000 dbar (75-term equation)`

USAGE:

`spiciness1 = spiciness1(SA,CT)`

DESCRIPTION:

```Calculates spiciness from Absolute Salinity and Conservative
Temperature at a pressure of 1000 dbar, as described by McDougall and
Krzysik (2015).  This routine is based on the computationally-efficient
expression for specific volume in terms of SA, CT and p (Roquet et al.,
2015).```
```Note that this 75-term equation has been fitted in a restricted range of
parameter space, and is most accurate inside the "oceanographic funnel"
described in McDougall et al. (2003).  The GSW library function
"gsw_infunnel(SA,CT,p)" is avaialble to be used if one wants to test if
some of one's data lies outside this "funnel".  ```

INPUT:

```SA   =  Absolute Salinity                                       [ g/kg ]
CT   =  Conservative Temperature                               [ deg C ]```
`SA & CT need to have the same dimensions.`

OUTPUT:

`spiciness = spiciness referenced to a pressure of 1000 dbar `

EXAMPLE:

```SA = [34.7118; 34.8915; 35.0256; 34.8472; 34.7366; 34.7324;]
CT = [28.8099; 28.4392; 22.7862; 10.2262;  6.8272;  4.3236;]```
`spiciness1 = gsw_spiciness1(SA,CT)`
`spiciness1 =`
