# gsw_z_from_depth

**height from depth**

## Contents

## USAGE:

z = gsw_z_from_depth(depth)

## DESCRIPTION:

Calculates height, z, from depth.
Note. Height z is NEGATIVE in the ocean. i.e. Depth is -z.
Depth is not used in the GSW computer software library.

## INPUT:

depth = depth [ m ]

## OUTPUT:

z = height [ m ]
Note. At sea level z = 0, and since z (HEIGHT) is defined to be
positive upwards, it follows that while z is positive in the
atmosphere, it is NEGATIVE in the ocean.

## EXAMPLE:

depth = [ 10; 50; 125; 250; 600; 1000;]

z = gsw_z_from_depth(depth)

z =
-10
-50
-125
-250
-600
-1000
