The following is a list of actions that should be accomplished prior to arriving at the first site. On cruises with short transit times before reaching the first site it is advisable to perform as many of the preparations in port as possible.
Paleomagnetics Lab
- Complete instrument checks by running basic measurements with the Kappabridge, JR6, and Cryogenic magnetometer to ensure instruments are functioning properly.
- Measure QAQC standards - pmag cubes with both JR6 and SRM, and empty SRM tray. Confirm that the data are consistent with previous expeditions with QCViewer. See Confluence Page QAQC Paleomagnetism Standard Operating Procedure for details.
- If core orientation is scheduled for your cruise, then replace all 9V batteries in the TransIT adapters on the two Flexit computers. If you are planning to use the MI5 Icefield tools, make sure the Palms are charged and batteries are available for each tool. Do not put the batteries in the tools until ready to start a survey. Download data from the tool to the PC to ensure data transfers are working.
- Train the scientists in the operation of the instruments used the most (e.g., Cryogenic Magnetometer, Agico spinner, Kappabridge magnetic susceptibility system).
- Go over the various software packages with the Paleomagnetics scientists (e.g., SRM, Dtech2000, Rema6, Kappabridge programs, and Puffin Plot). It is especially important to familiarize the scientists with the operation of the SRM. The User Guide and Quick Start guide can be found on IODP Share.
- The scientists may want to use specific software for coding or processing data. Check with them prior to arrival on site and facilitate software installation if necessary.
- Remove any old or replicated SRM measurement sequences from C:\IMS\SRM CONFIG\Measurement Sequence\User
- Clear out extraneous sample shape presets from the IMS-SRM software and make sure the appropriate presets for the expedition are available.

The following is a list of actions that are accomplished once on site by technicians alone or cooperatively with the scientists assigned to the laboratory for an expedition.
A. SAMPLING
The basic magnetic measurements are conducted on whole/split sections and discrete samples:
