Figure 3 Cube Orientation for Standards
The QAQC Text_ID created for IODPSTD01 to IODPSTD12 considers the samples as they were taken from the WORKING HALF. Put the sample upside down in the discrete tray in the position WTA, top away (arrow of the cube away from the SRM) and +X down.

Table 2. IODP Standards created by Scripps measured with the SRM onboard the JR. Declination, inclination and intensity are corrected from background and drift (April 18, 2022). Volume is 7 cc.
IODP created Standards
...
Because the standards provided by Lisa Tauxe at Scripps were not designed to be used in the JR-6, 4 new standards were created which can be used in the JR-6. A strip of magnetic tape was glued to a stick which is secured inside a J-cube. The standards were then given an IRM and measured in the JR-6 followed by the SRM. These standards are oriented as if they were collected from a working half with an assumed volume of 7cc . Each standard was measured 20 times. The process included inserting and removing the standard between each measurement. The mean intensity was calculated as well as Fischer stats for inclination and declination. See table below.
