Again, please note that it will be necessary to cover the core surface with Ultralene Ultralene® film and GLAD® Plastic Wrap in order to protect the nose of the instrument and the underside of the shield from contamination. See Preparing Section Halves, below.
Important! Do not measure the core section half without covering it with film!

Put a sample label onto the cup. Remove excess Ultralene Ultralene® to help the label stick. The discrete sample is now ready for analysis.

- Run Number: A sequential number increased by +1 with every measurement, ex: 1, 2, 3… This number should start at 1 for the first measurement of the expedition. This should be unique throughout the expedition, so the use of a logsheet is highly recommended.
- Sample Name: Sample name according to the sample or section half label. Ex: 366-U1234A-20F1-W.
- Text ID: Unique database identifier for each sample or section half located under the barcode on the label. Ex: SHLF8638181
- Offset for SHLF: The point where a measurement was taken, measured as distance from the top of the section. Leave this field blank for discrete samples. Note: Be sure to enter one singe single number, not a range. (Example: Wrong 100-101, Correct: 100.5)
- Comment: A brief description of the measurement. An optional field.
First enter the run number manually. Then put the cursor in the 'Sample Name' field and scan the label with a barcode scanner. Use the barcode scanner labeled SECTION HALF for section halves and the scanner labeled DISCRETE for discrete samples. This will populate the 'Sample Name' and 'Text ID' fields. If measuring a section half enter the 'Offset for SHLF'; leave this field blank for discrete measurements.
Important! Click Save in the lower right portion of the screen.
If you do not click 'Save', the sample information will revert back to values entered for the previous run and the new measurement will have the same name as the previous one. The measurements are parsed by time so measurements will not overwrite one another; however, there will be multiple measurements with the same information, and the data will have to be sorted out later.
These The barcode scanners scanner have been programmed to properly parse the different kind of label for section halves and other types of samples. The fields should fill with the label ID (e.g., 366-U1498B-23R-3-W…) and text ID (e.g., PWDR8638211). If they are not working correctly reprogram the scanners by going to IODP_SHARE > XRF > Barcode Rules and scan the rule set.
If the user needs additional fields to describe the sample or the measurements being done, the technician can modify the method to enable up to 11 additional user-defined fields. To see how to add fields refer to the section 'How to Add Fields to Sample Information Window'.
