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"
.
