R: Vertical coordinate

swZ {oce} | R Documentation

## Vertical coordinate

### Description

Compute height above the surface. This is the negative of depth, and so is defined simply in terms of `swDepth`.

### Usage

    swZ(pressure, latitude = 45, eos = getOption("oceEOS", default =
      "gsw"))

### Arguments

`pressure` | either pressure [dbar], in which case `lat` must also be given, or a `ctd` object, in which case `lat` will be inferred from the object.
`latitude` | Latitude in degN or radians north of the equator.
`eos` | indication of formulation to be used, either `"unesco"` or `"gsw"`.
