5. Reports

5.1. Correlation (affine and splice) table reports

Stratigraphic correlation data is reported in four types of reports (Fig. 5-1, lower left):

  • List of affine tables
  • Affine tables
  • List of splice interval tables
  • Splice interval tables

Figure 5-1. Screen capture of correlation reports options within the LIMS Reports framework.


List of affine tables report

This report lists the CCSF alternate depth scales available in LIMS, and the original affine table files that the scales are derived from, one per row (Fig. 5-2). Metadata for each scale are provided as well (see Table 6 for column descriptions). The list can be filtered by entering an expedition number.

To get a list of affine tables report (Fig. 5-2):

  • In the Select report panel, expand the Stratigraphic Correlation list and select List of affine tables report.
  • In the Hierarchy Search area, filter by Expedition(s), if so desired.
  • View data on screen using the View data button.
  • Option: download data in CSV format using the Download tabular data button.

Table 5-1. Description of List of affine tables report columns.

Column name

Description

Alternate depth scale (CCSF) name

This formal name is auto-generated at the time of upload, based on the contents of the affine table file uploaded by the user and an optional, up to 10 character long extension at the end (after the date) directly entered by the user.

Uploaded affine table file name and link

The file name is exactly the same as that of the original, unaltered user file, which can be downloaded via the link.

Date and time of upload

Date and time based on database server settings.

User comment

User who uploaded the affine table file may have entered an optional comment at the time of file upload, to communicate pertinent process or file information to future users of the data.

Name of account used to upload

Name of the LIMS user account that was used to upload the affine table file.


Affine tables report

This report provides the full affine table information, one core per row (Fig. 5-3; see Table 5-2 for descriptions of columns). Sample identity information (i.e., hole and core) and the cumulative offset for each core resulting from depth shifting, are derived directly from user-uploaded files. However, the CSF-A and CCSF depths as well as differential offset and growth rate are computed in LIMS, based on latest sample registry data for hole and core. The original, unaltered affine table user file can also be downloaded.

To get an affine table report (Fig. 5-3):

  • In the Select report panel, expand Stratigraphic Correlation list and select Affine Tables report.
  • In the Additional Filters area, use the Alternate depth scale choice list to select the scale corresponding to the appropriate affine.
    • You can reduce the choice list by selecting an expedition from the Expedition(s) filter in the Hierarchy Search area.
  • View data on screen using the View data button.
  • Option: download data in CSV format using the Download tabular data button.


Figure 5-3: Affine table report.



Table 5-2. Description of Affine tables report columns.

Column name

Description

Site, Hole, Core, Type

Sample identity of the core.

Depth CSF-A (m)

Top of core depth from the LIMS sample registry at the original CSF-A depth scale.

Depth CCSF (m)

Top of core depth at the CCSF alternate depth scale.

Depth CCSF (m) = Depth CSF-A (m) + Cumulative offset (m)

Cumulative offset (m)

Distance a core was shifted along the depth axis relative to the original CSF-A depth.

Differential offset (m)

Distance a core was shifted along the depth axis relative to its depth after the next shallower core was shifted. This value, when viewed in context, is useful to detect unusual shifts that may indicate a correlation error or stratigraphic irregularity.

Growth rate

Growth rate = Depth CCSF (m) / Depth CSF-A (m); a measure of the degree of expansion in the recovered sediment section relative to the in-situ section.

Shift type (optional comment)

Recommended terms are: anchor, tie, set, and append. See section 2 of this user guide for explanation.

Data type used (optional comment)

Recommended terms are analysis names or acronyms, such as NGR, MSL, RGB, etc.

Quality comment (optional comment)

Recommended comments are those pointing to problematic shifts based on less than ideal signal.


List of splice interval tables report

This report lists the splice interval tables available in LIMS, one per row, including metadata and links generated by the LIMS or added by the user at the time of file upload (Fig. 5-4; see Table 5-3 for description of columns). The list can be filtered by entering an expedition number.

To get a list of splice interval tables report (Fig. 5-4):

  • In the Select report panel, expand Stratigraphic Correlation list and select List of Splice Interval Tables report.
  • In the Hierarchy Search area, filter by Expedition(s), if so desired.
  • View data on screen using the View data button.
  • Option: download data in CSV format using the Download tabular data button.

Table 5-3. Description of List of splice interval tables report columns.

Column name

Description

Splice name

This formal name is auto-generated at the time of upload, based on the contents of the splice interval table file uploaded by the user and an optional, up to 10 character long extension at the end (after the date) directly entered by the user.

Associated CCSF scale (affine table)

CCSF alternate depth scale (based on affine table), selected by the user who uploaded the splice interval table.

Uploaded splice interval table file name and link

The file name is exactly the same as that of the original, unaltered user file, which can be downloaded via the link.

Uploaded splice tie point table file name and link

Upload of this type of file is optional. File name, if present, is exactly what users named it; link downloads the unaltered file.

Date and time of upload

Data and time based on database server settings.

User comment

User who uploaded the splice interval table file may have entered an optional comment at the time of file upload, to communicate pertinent process or file information to future users of the data.

Name of account used to upload

Name of the LIMS user account that was used to upload the affine table file.


Splice interval tables report

This report provides the full splice interval table information, one interval per row (Fig. 5-5; see Table 5-4 for descriptions of columns). Sample identity information (i.e., hole, core, section, offset) is derived directly from user-uploaded files. However, the CSF-A and CCSF depths are computed in LIMS, based on latest sample registry data for hole and core. The original, unaltered splice interval table user file can also be downloaded.

To get an affine table report (Fig. 5-5):

  • In the Select report panel, expand Stratigraphic Correlation list and select Splice table report.
  • In the Splice Search area, use the choice list to select the appropriate splice.
    • You can reduce the choice list by selecting an expedition from the Expedition(s) filter in the Hierarchy Search area.
  • View data on screen using the View data button.
  • Option: download data in CSV format using the Download tabular data button.

5.2. Alternate depths

This report feature provides CCSF alternate depth for any sample and data point in any data report that uses depth (CSF-A) as the primary independent variable. User must select the appropriate alternate scale for a report.

To retrieve CCSF depths with data (Fig. 5-6):

  • In the Select report area, select desired data type by expanding the category of interest.
  • In the Hierarchy Search area, filter Expedition(s), Site(s), Hole(s), Core(s), etc., as needed.
  • In the Additional Filters area, select the appropriate Alternate depth scale from the choice list.
  • View data on screen using the View data button. The alternate depths will be shown in the column nest to the CSF-A depths.
  • Option: download data in CSV format using the Download tabular data button.

Figure 5-6. Data report example with alternate depths shown in column #10.



5.3. Data by splice

One of the major goals of stratigraphic correlation is to generate “spliced data”, or to retrieve “data by splice”. To get data by splice (Fig. 5-7):

  • In the Select report area, select desired data type by expanding the category of interest.
  • In the Splice Search area, select the appropriate splice from choice list.
  • You can filter the splice list by selecting an expedition in the Hierarchy Search area.
  • View data on screen using the View data button. The alternate depths will be shown in the column nest to the CSF-A depths.
  • Option: download data in CSV format using the Download tabular data button.
