\usage{
swZ(
  pressure,
  latitude = 45,
  eos = getOption("oceEOS", default = "gsw"),
  debug = getOption("oceDebug")
)
}
\arguments{
\item{pressure}{either pressure (dbar), in which case \code{latitude} must also
be given, or a \code{ctd} object, in which case \code{latitude} will be inferred
from the object.}

\item{latitude}{numeric value for latitude in degrees North.}

\item{eos}{character value indicating the formulation to be used, either
\code{"unesco"} or \code{"gsw"}.}

\item{debug}{an integer specifying whether debugging information is
to be printed during the processing. This is a general parameter that
is used by many \code{oce} functions. Generally, setting \code{debug=0}
turns off the printing, while higher values suggest that more information
be printed. If one function calls another, it usually reduces the value of
\code{debug} first, so that a user can often obtain deeper debugging
by specifying higher \code{debug} values.}

\description{
Compute height above the surface. This is the negative of depth,
and so is defined simply in terms of \code{\link[=swDepth]{swDepth()}}.
