Table 1 contains the values of the standards as they were measured in California before receipt by IODP. Note that the units of intensity in the provided values was in emu and the volume used was 1cc. Intensity has been converted to A/m as this is the unit used by IODP instruments and the intensity has also been listed if you assume a 7cc volume.. The conversion used was 10-1 A/m = 10-3 emu. It is extremely important that these standards do not get demagnetized. Be sure to stress this to anyone who may use the standards.

Standard Orientation
The Samples are oriented as if they were taken from an archive half. This can be confusing as most of the time, discrete samples would be collected from the working half. Be sure to keep this orientation in mind when loading into the instruments. See Figure 3 for sample orientation arrows
