- Check the vital signs of the Cryogenic Magnetometer. Use the electronics interfaces to measure the vital signs inside the magnetometer: SQUID temperature and shield temperature. Record the values on the log sheet (found in the Lab Notebook /wiki/spaces/LN/pages/7338168246).
- Check water level and condition inside the Haskris. Check the CryoWATCH software to monitor the compressor oil and water temperatures. Create a new log file for the expedition in C:\Users\daq\Desktop\Cryo Logs. For more detailed instructions refer to the SRM user guide.
- If a service call is scheduled, make sure you prepare all supplies necessary for it. Find the service representative.

- Measure the interior field of the magnetometer using the 3-axis fluxgate ("field profile"). Use the DAFI utility in the IMS-SRM software. Save the excel file to IODP Share: Pmag_Documents: SRM: Field Profiles. Each file should be labeled with the date of measurement.
- If it is necessary to heat the SQUIDs to release a trapped field, follow the field trapping procedure in the user guide.
- Check the field produced by the degauss coils within the SRM using the axial and transverse Hall probes
- Introduce scientists to the cryomagnetometer and run basic measurements, such as:
- Clean the tray and demagnetize at a field of 30 mT or higher and measure the tray. Measure the tray as a fake sample and compare results to ensure corrections are done properly. This should be done with the section half and, if applicable, the discrete tray.
- Conduct positioning tests along the track with a section half tray. Testing should be done with an empty, light tray and a weighted, heavy tray. Check discrete boat positioning as well.
- Measure a split core or play core.
- Check to see if any regular maintenance projects need to be completed. Specifically check if the adsorber in the Cryomech compressor is due for replacement. If the bi-annual replacement of the adsorber is required, swap the entire Cryomech compressor with the spare compressor. Record the date of the change (place sticker on compressor).
- Provide safety tour to all scientists who work in the Paleomagnetic lab area. Ensure all scientists understand the safety concern and sign sign document required
III. SITE PREPARATION - Prior to arrival on site and core on deck
