an integer specifying whether debugging information is

is used by many
oce functions. Generally, setting

be printed. If one function calls another, it usually reduces the value of

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
a non-zero value to be subtracted from pressure.
