ctd object is assembled from the contents of the rsk object.
The data and metadata are mostly unchanged, with an important exception: the
pressure item in the data slot may altered, because rsk
instruments measure total pressure, not sea pressure; see “Details”.
rsk2ctd(x, pressureAtmospheric = 0, debug = getOption("oceDebug"))rsk object, i.e. one inheriting from rsk-class.object before storing it in the return value.oce functions. Generally, setting debug=0
turns off the printing, while higher values suggest that more information
be printed.pressureType element of the
metadata of rsk objects defines the pressure type, and this controls
how pressure is set up in the returned object. If object@metadata$pressureType
is "absolute" (or NULL) then the resultant pressure will be adjusted
to make it into "sea" pressure. To do this, the value of
object@metadata$pressureAtmospheric is inspected. If this is present, then
it is subtracted from pressure. If this is missing, then
standard pressure (10.1325 dbar) will be subtracted. At this stage, the
pressure should be near zero at the ocean surface, but some additional adjustment
might be necessary, and this may be indicated by setting the argument pressureAtmospheric to
a non-zero value to be subtracted from pressure.
