* <u>'''Default data type'''</u> of a parameter can be ''numeric'' (1), ''text'' (2), (3) ''DateTime'' given in [http://en.wikipedia.org/wiki/ISO_8601 ISO-format]: YYYY-MM-DDThh:mm:ss, (4) ''binary'', (5) ''Feature'', (6) ''URI'', and (7) ''Event''. If a text parameter is defined, no unit, format and min/max values should be given. <u>Example:</u> ''Carbon, organic, dissolved [µmol/kg]'' is a ''numeric'' parameter.
* '''Default method''' (DefaultMethodID) is a relational field to the [[Method]] table where a required method has to be defined first. Methods defined in this field are shown during import of data by default. The default can be changed during the import procedure. Use the '''ID''' of the method for import. <u>Example:</u> ''Carbon, organic, dissolved'' is ''calculated'', Method ID ''50''.
* '''Reference''' (ReferenceID) can be given in case a parameter was defined through a publication; relational to [[Reference]]. Use the ID of the referenceI for import. There reference is not shown in the dataset. it is better to use the ''URL field''
* '''URL''' may contain a link to a more detailed explanation/definition of the parameter, e.g. in [http://en.wikipedia.org/wiki/Main_Page Wikipedia] or in a paper. You can give a link or a [[DOI]]. This definition should be of general use. For species parameter the URL field will automatically filled with a link to a taxonomic database (e.g. [http://www.itis.gov ITIS], [http://www.marinespecies.org WORMS]).
* '''Comment''' (Description) may be used for any descriptions, helpfull to other curators to understand its meaning. This is an ''internal'' info field, its content does not appear in datasets!
* '''Keywords''' may be used to define a certain parameter group for special purpose, projects or users.

Data submissions are required to use parameters, as defined in the dictionary. Parameters are always accompanied by a unit. New parameters are defined by the Editor in Chief on request.

The parameters related to a dataset are listed in the dataset metaheader.

Definition of parameters

Mandatory fields are underlined; unused columns and lines in import files should be deleted.

  • Parameter Name contains the full name of the parameter. Parameter Name in combination with the unit must be unique in Pangaea. Parameter names have the most important specification in the beginning, followed by all describing therms in hierarchic order. Example: when dissolved organic carbon is measured, carbon is the main parameter information, followed by organic and the description of it's condition dissolved = Parameter Name Carbon, organic, dissolved. Do not use abbreviations in the parameter name. Compare the new parameter name with existing parameters and follow their syntax.
  • Abbreviation or short name of the parameter; is used in the header of data sets. The Abbreviation gives a short form of the parameter name, it never contains comma. Delta notation is given by d, standard deviation and standard errors are std dev and std e. Example: abbreviation of the parameter Carbon, organic, dissolved is DOC.
  • Unit should be given for all numeric-parameters and should follow standard use i.a. already existing parameter should only be defined with an other unit if the values can not be converted from one to an other. The unit does not contain chemical formulas, elements or the sampling milieu. This must be given in the Parameter name. Text-parameters have no unit, delete the unit column in import form or leave empty. Example: parameter Carbon, organic, dissolved has the unit µmol/kg not µmol C/kg.
