# gsw_depth_from_z

**depth from height**

## Contents

## USAGE:

depth = gsw_depth_from_z(z)

## DESCRIPTION:

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

## INPUT:

z = height [ m ]

## OUTPUT:

depth = depth [ 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:

z = [ -10; -50; -125; -250; -600; -1000;]

depth = gsw_depth_from_z(z)

depth =

10
50
125
250
600
1000
