Translate data names in the ODF convention to similar names in the Oce convention.


  ODFunits = NULL,
  columns = NULL,
  debug = getOption("oceDebug")



Vector of strings holding ODF names.


Vector of strings holding ODF units.


Optional list containing name correspondances, as described for read.ctd.odf().


Optional list containing information on the data variables.


an integer specifying whether debugging information is to be printed during the processing. This is a general parameter that is used by many oce functions. Generally, setting debug=0 turns off the printing, while higher values suggest that more information be printed. If one function calls another, it usually reduces the value of debug first, so that a user can often obtain deeper debugging by specifying higher debug values.


The following table gives the regular expressions that define recognized ODF names, along with the translated names as used in oce objects. If an item is repeated, then the second one has a 2 appended at the end, etc. Note that quality-control columns (with names starting with "QQQQ") are not handled with regular expressions. Instead, if such a flag is found in the i-th column, then a name is constructed by taking the name of the (i-1)-th column and appending "Flag".

Any code not shown in the list is transferred to the oce object without renaming, apart from the adjustment of suffix numbers. The following code have been seen in data files from the Bedford Institute of Oceanography: ALTB, PHPH and QCFF.


A vector of strings.

A note on unit conventions

Some older ODF files contain non-standard units for conductivity, including mho/m, mmho/cm, and mmHo. As the units for conductivity are important for derived quantities (e.g. salinity), such units are converted to standard units (e.g. S/m and mS/cm). (This was once done with a warning, but on 2020-02-07 the warning was removed, since it did not indicate a problem with the file or the data scanning; rather, it was a simple matter of nudging towards uniformity in a way that ought to confuse no users, akin to converting m**3 to m^3, which is also done here without warning.)

Consistency warning

There are disagreements on variable names. For example, the “DFO Common Data Dictionary” (reference 1) has unit millimole/m^3 for NODC and MEDS, but it has unit mL/L for BIO and IML.
