Compute height above the surface. This is the negative of depth,
and so is defined simply in terms of swDepth().
swZ(pressure, latitude = 45, eos = getOption("oceEOS", default = "gsw"))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 in \(^\circ\)N or radians north of the equator.
indication of formulation to be used, either "unesco" or
"gsw".
