The Data Resource Files are those files which the Data Mining Program and Relational Database Generator operate on.

The data of these ASCII format files is arranged in tree structure:
              Data Set
                  Seafloor Site
                      Subottom depth
                            Segregation
                                   Data Theme
                                        Data Field

• Each Data Set is dealt with by a 'SRC' record.
• Each Seafloor Site is described by a 'SFS' record.
• Data Type refers to the disposition of an observation in Subbottom Depth / Segregation.
• Data Themes divide the information into subjects such as Lithology, Acoustic Properties, Colour, Texture, Grainsizes, Composition and Geotechnical Properties.
• The Data Fields are comma delimited and define individual data items such as an analysis, an observation, etc.

These appear as Field 1 for each data item, and have values as follows:

0 = Metadata including formatting/ comments/ bibliography/ lab details/ personnel, etc.;
1 = Site characterization including sample at or closest to seafloor (navigation/ measured parameters and technical data);
2 = Sample from the subsurface/ below topmost sample (e.g. successive samples down core);
3 = Subsamples or phases (layers/ clasts/ etc.) taken successively from one level in the subsurface or from within the surface sample;
4 = Data derived on the basis of other reported data
5 = Interpolated data (e.g./ from re-gridding inside a polygon);
6 = Not Used
7 = Not Used
8 = Incomplete or incorrect data (record and dependent lines not to be processed)
9 = Time series entry.

Data Themes divide data items into groups of common interest. They are denoted by a 3-letter Alphabetic code (Capitals) in Field 2 of each record.
They include:

Individual data items are allotted to special fields within their Data Theme.

These are laid out best and most recently in db9_dataentry.htm (dated 20 March 2002) which is your main guide to placement of input data.

But page db9_data_fields (dated April2001) provides many extra the details. From this table, the user can check for many parameters, the:
