either pressure [dbar], in which case <code>lat</code> must also
be given, or a <code>ctd</code> object, in which case <code>lat</code> will be inferred
from the object.

pressure

Latitude in \(^\circ\)N or radians north of the
equator.

latitude

indication of formulation to be used, either <code>"unesco"</code> or
<code>"gsw"</code>.

Compute height above the surface. This is the negative of depth,
and so is defined simply in terms of <code><a rd-options="" href="/link/swDepth?package=oce&version=1.0-1" data-mini-rdoc="oce::swDepth">swDepth</a></code>.

Supports the analysis of Oceanographic data, including 'ADCP'
measurements, measurements made with 'argo' floats, 'CTD' measurements,
sectional data, sea-level time series, coastline and topographic data, etc.
Provides specialized functions for calculating seawater properties such as
potential temperature in either the 'UNESCO' or 'TEOS-10' equation of state.
Produces graphical displays that conform to the conventions of the Oceanographic
literature.

swZ function

Compute height above the surface. This is the negative of depth,
and so is defined simply in terms of <code><a rd-options='' href='swDepth'>swDepth</a></code>.
