Parameters¶
About Parameters¶
The CCHDO works frequently with many parameters common in hydrography. Provided here is a description of many common parameters encountered in exchange files.
Warning
This list may not contain every parameter which may be encountered in an exchange file. CCHDO is working on providing a machine readable list of ALL parameters which may be encountered in all files. This list will include parameters which CCHDO lacks a description for (known unknown parameters).
Until that time, parameters may appear in exchange formats from the CCHDO which are not documented here. No undocumented parameter or field will cause data integrity or usefulness issues (i.e. all undocumented parameters may be safely ignored).
Definitions¶
Provided with each parameter is a set of information in a table, the information included in that table should be interpreted as follows:
- Units:
These are the common units encountered for this parameter as it will appear in the exchange document itself. The special units of “None” means the field will be either blank or contain only whitespace.
- Data Type:
Specifies the allowed type of data in the data records for this parameter. There are three types of data, string (str), integers (int), and decimal. String data types may be any printing character except a comma
,which is the field seperator. Integer data types may only contain numbers without a decimal point, quality flags are usually integers. Decimal data types may be any real number (including an integer) and may include decimal point, the precision is not specified.- Quality Flags:
Specifies which set of quality flag definitions should be used to interpret a quality flag column for this parameter (if present). Current quality flags are: bottle, water, ctd. See the Quality Codes section for more information
- Error Column Label:
A parameter might contain an error or uncertanty value associated with it. The column which contains the error/uncertanty values for this parameter will have the name listed in this field.
- CF/netCDF Attributes:
When this parameter appears in a CF netCDF file, the units and standard name are determined by the units of the WHP parameter. Not all parameter/unit pairs have CF standard names yet. Some WHP units are not allowed in the units attribute of valid CF netCDF files, of particular note are the temperature units of ITS-90 and IPTS-68 which are both mapped to degC in CF files. These “units” will instead appear in a
reference_scaleattribute of the variable rather than in theunitsattribute.
Unlisted Parameters¶
Otherwise valid exchange files which contain parameters, units, or parameter/unit pairs that are not listed in the Parameters list SHALL NOT cause the file to be invalid so long as the rest of the specification is adhered to.
Pass Through¶
Authors of software which read and write exchange files SHOULD pass though unlisted parameters, units, parameter/unit pairs, and the associated data columns.
Note
This section is intended for software which is used in data management, it does not impose a requirement on authors only wishing to do analysis.
Parameters¶
This section was generated automatically from a
machine readable list of parameters,
there is also a
validation schema for the
parameters json.
CCHDO Parameter database version: 2025.10.0.
EXPOCODE¶
- Units:
None
- Data Type:
string
- CF/netCDF Attributes:
nc_varnamewhp_unitunitsstandard_nameexpocodeNoneNoneNone
The expedition code, assigned by the CCHDO or generated by the user. Used as the unique identifier for the cruise. Usual generation formula is ICES 4 character platform code then the cruise departure date in YYYYMMDD format. The underscore _ character may also be present.
Warning
There is no requirement that the value in EXPOCODE be the same for an entire bottle file or across CTD profiles in a single zip archive. This will often occur when cruises are combined into a single file.
SECT_ID¶
- Units:
None
- Data Type:
string
- CF/netCDF Attributes:
nc_varnamewhp_unitunitsstandard_namesection_idNoneNoneNone
If a repeat of a WOCE section, this is the WHP section identifier. Examples include: A12, A13.5, P02.
Note
There may be inconsistency in the how line numbers are represented. For example, P02 might be present as P2, these represent the same SECT_ID. Two digit zero padded line numbers are the canonical representation, please inform the CCHDO if non zero padded line numbers are encountered.
LINE¶

- Data Type:
string
- CF/netCDF Attributes:
nc_varnamewhp_unitunitsstandard_nameline_idNoneNoneNone

- CF/netCDF Attributes:
nc_varnamewhp_unitunitsstandard_nameevent_numberNoneNoneNone
Non program specific event number. Some cruises or programs keep track of sequential events that occur on a cruise or across multiple cruises of the same program. There exists program specific event number names of GEOTR_EVENT, BIONBR, and BIOS_CASTID that should be used if they are more appropriate.
BTLNBR¶
- Units:
None
- Data Type:
string
- BTLNBR_FLAG_W Definitions:
- CF/netCDF Attributes:
nc_varnamewhp_unitunitsstandard_namebottle_numberNoneNoneNone

Note
The bottle number MAY have quality flags.
Warning
Despite the name, the value IS NOT numeric, ensure that any software reading the file can handle UTF-8 data of the specified allowed code points. The CF/netCDF files force the data type to be char, but for historic reasons, the variable name is maintained as bottle_number.
DATE¶
- Units:
None
- Data Type:
string
- CF/netCDF Attributes:
nc_varnamewhp_unitunitsstandard_namedateNoneNoneNone
The UTC date in zero padded YYYYMMDD format. The date reported is usually cast bottom for Bottle files and cast start for CTD files. Valid range for YYYY: 0001-9999. Valid range for MM: 01-12. Valid range for DD: 01-31 (depends on month and year). The format of dates corresponds to the C-strftime format of %Y%m%d.
The date should be read as a string, but be able to be cast unambiguously to an integer. To convert from integer representation, left pad zeros to match the date format description. For example, the integer 8020202 is the date 08020202 or Feb 2nd, 802. This is a very unlikely situation.
TIME¶
- Units:
None
- Data Type:
string
- CF/netCDF Attributes:
nc_varnamewhp_unitunitsstandard_nametimeNoneNoneNone
The UTC time in zero padded hhmm format. A single time should be reported for each cast, usually the time at cast bottom (deepest) is used. The order of preference for the reported time is: cast bottom, cast start, cast end (i.e if cast bottom is not available, the cast start time should be used).
Valid range for hh: 00-24 Valid range for mm: 00-59 The format of times corresponds to the C-strftime format of %H%M.
The time should be read as a string, but be able to be cast unambiguously into an integer. To convert from an integer, left pad zeros to match the time format description.
Note
Times represented as integers will be present in whp COARDS netcdf files. Times in netcdf files will be anywhere from 1 to 4 digits. E.g. a time of 6 as in integer represents 6 minutes after midnight or 0006
Midnight is a special case in that it has two valid representations: 0000 and 2400. The date 20140202 at time 0000 is the same instant as the date 20140201 at time 2400. This corresponds to times allowed by ISO 8601.
Use BTL_TIME to report the time of individual bottle closures.
CF netCDF files will use the standard Time Coordinate as specified in the conventions
Warning
Time is not a required parameter! If time is not present, then the temporal resolution of the data is reduced to a 24 hour period. It is the responsibility of the user of the data to omit files/casts which do not meet their temporal resolution requirements.
LATITUDE¶
- Units:
None
- Data Type:
decimal
- CF/netCDF Attributes:
nc_varnamewhp_unitunitsstandard_namelatitudeNoneNonelatitude
The latitude as a signed decimal number. By convention, is positive in the northern hemisphere and negative in the southern hemisphere. Positive values do not include a + character (U+002B), negative values are prefixed with a - character (U+002D).
Note
Only one latitude SHOULD be reported for a cast, typically this is the ship position when the cast is at the bottom (deepest), but this is not guaranteed.
Use BTL_LAT to include positions of individual bottle closures.
Warning
Since this parameter has no units, the positive in the northern hemisphere and negative in the southern hemisphere MUST be strictly adhered to.
The geographic coordinate system is not currently reported.
LONGITUDE¶
- Units:
None
- Data Type:
decimal
- CF/netCDF Attributes:
nc_varnamewhp_unitunitsstandard_namelongitudeNoneNonelongitude

Note
Only one longitude SHOULD be reported for a cast, typically this is the ship position when the cast is at the bottom (deepest), but this is not guaranteed.
Use BTL_LON to include positions of individual bottle closures.
The longitudes of -180 and 180 describe the same meridian.
Warning
Since this parameter has no units, the positive in the eastern hemisphere and negative in the western hemisphere convention MUST be strictly adhered to.
The geographic coordinate system is not currently reported.

The concentration of dissolved nitrate plus nitrite in sea water. The chemical formula for the nitrite anion is NO2-.
Note
Most modern techniques for determining dissolved nitrate return a value of nitrate (NO3) plus nitrite (NO2). A separate determination is then done for nitrite and the result subtracted by the data originator to obtain nitrate. If no separate nitrite determination was carried out - or in rare cases the nitrite number was not subtracted - data providers should list the result as NO2+NO3. Because nitrite values are in most regions small compared to nitrate, most data users will not adversely affect their results by relabeling NO2+NO3 as NITRAT.

The fugacity is the measured pressure (or partial pressure) of a real gas corrected for the intermolecular forces of that gas, which allows that corrected quantity to be treated like the pressure of an ideal gas in the ideal gas equation PV = nRT. The partial pressure of a dissolved gas in sea water is the partial pressure in air with which it would be in equilibrium. The partial pressure of a gaseous constituent of air is the pressure that it would exert if all other gaseous constituents were removed, assuming the volume, the temperature, and its number of moles remain unchanged. The chemical formula for carbon dioxide is CO2.

Warning
This parameter was added because we found several cruises with “PCO2” reported as ppm. The only notes that could we could find where questioning if the values were “wet” or “dry”, which is wondering if pH2O was taken into account. XCO2 as a name was taken from the definition of CO2 expressed as PPM in CO2SYS V25.
Use caution if you are trying to compare this parameter to other (p/f/x)CO2 data

Radiative flux is the sum of shortwave and longwave radiative fluxes. In accordance with common usage in geophysical disciplines, “flux” implies per unit area, called “flux density” in physics. The volume scattering/absorption/attenuation coefficient is the fractional change of radiative flux per unit path length due to the stated process. Coefficients with canonical units of m2 s-1 i.e. multiplied by density have standard names with specific_ instead of volume_. The scattering/absorption/attenuation coefficient is assumed to be an integral over all wavelengths, unless a coordinate of radiation_wavelength is included to specify the wavelength. Attenuation is the sum of absorption and scattering. Attenuation is sometimes called “extinction”. Beam attenuation refers to the decrease of radiative flux along the direction of the incident path. It is distinguished from attenuation of the downwelling component of radiative flux from any incident direction, also called “diffuse” attenuation. Corrected for pure water attendance means the attenuation coefficient has been adjusted/calibrated to remove the influence of absorption/scattering from the water itself.

chlorophyll-a. Chlorophylls are the green pigments found in most plants, algae and cyanobacteria; their presence is essential for photosynthesis to take place. There are several different forms of chlorophyll that occur naturally. All contain a chlorin ring (chemical formula C20H16N4) which gives the green pigment and a side chain whose structure varies. The naturally occurring forms of chlorophyll contain between 35 and 55 carbon atoms. Chlorophyll-a is the most commonly occurring form of natural chlorophyll.

Enrichment of 15N vs 14N in N2O (nitrous oxide) where the substitution has occurred at the center position of the N2O molecule as compared to a standard. N2O where the substitution has occurred in the end nitrogen atom is called D15N_BETA and is not usually measured. D15N_BETA can be calculated from bulk D15N and D15N_ALPHA using equation 25 from Toyoda and Yoshida 1999 [Toyoda1999]
Toyoda and Yoshida give the value of A=0.998, though this needs to be determined experimentally for the standard in use. We have seen data using a value of A=1 in data submitted to CCHDO.
