- Make sure supplies are adequate and equipment and instruments are operational and notify Lab Officer of any problems.
- Calibrate Pycnometer and all tracks.
- Calibrate Mettler Toledo balances: Balance calibration should be carried out while the ship is in port and is as stable as possible.
Report to LO/ALO for other port call duties.
- Provide training to all Physical Property scientists on instrument operation (WRMSL, STMSL, SHMSL, ThermCon, Gantry, MAD, NGR, XMAN XMSL, XSCAN), sample preparations, and data upload/download procedures.
- Provide safety tour to all scientists working in the Physical Property area. Ensure scientists understand all safety concern and sign document required.
...
- Place log sheets and instrument's Quick Users Guide at each station. Organize prior Expedition's log sheets (if not already done so) for shipment back to IODP.
Reset all run numbers prior to calibrations; this is not necessary, but it is a good idea to make new instrument software log files and rename the old ones w/ the prior Expedition's number in the name.
- Make sure that the motion control systems have found home and the position of the laser for all instruments using M-Drive.
- Perform calibrations for all tracks prior to first core on deck at each Site.
...
- P-Wave Y & Z spears: using the water boat.
- P-Wave X axis calipers: using aluminum standardacrylic standards.
XSCAN: For more detail, consult the XSCAN Image Logger User Guide
- Perform tube seasoning of the source in use and the spare source.
Index PropertiesMAD station: For more detail consult the Moisture and Density User & Quick Guides.

- Assist in core processing according to the Core Lab SOP. This is a primary function of any marine technician (with few exceptions like chemistry technicians, who have a different role) and should be your highest priority.
- If there are physical properties lab-related tasks that need to be performed then coordinate that work vs. the core processing with the ALO on duty.
- Ensure that data is being correctly uploaded to the LIMS.
- Check QAQC of all instruments and calibrate as needed.
- Dry out/replace silica desiccant (MAD station) as needed.
- Perform tube seasoning of the source in use and spare source for the XSCAN every week (for instance, on Safety Sunday).
V. DURING EXPEDITION
- Keep Lab Clean and Orderly
- Continue processing cores through the lab as described above
- Receive core and assist as needed in the core lab (i.e. splitting, restocking, boxing core, disposing of trash, and general cleaning and maintenance of core lab). Remember, the core lab is your primary duty and other tasks must come secondary to that unless arrangements are made with the Lab Officer to meet special objectives. For details on Core lab responsibilities refer to the Core lab SOP.

- Write the end-of-Expedition lab report, give a copy to the Lab Officer.
- Make sure all data are sent to LIMS before the MCSs cut off database access. All non-essential data should be erased from the hard disks of all the computers.
- All Expedition data needs to be placed on data1 and removed from instrument host prior to handing the lab over to the oncoming technician. This includes all files in DATA, AUX_DATA, ARCHIVE, and ERROR folders.
Pack upScan all log sheets and placed a copy in the appropriate measurement folder in DATA1. If the log sheet is not associated to a current folder, place them in the subfolder "1.9. Laboratory Log Sheets". They could be organized by site or one file for the whole expedition. They should be saved in .pdf format, by log sheet type and named following the convention "logsheets_[analysis]_[exp and/or site].pdf" (e.g., logsheets_TCON_398-U1590.pdf). Log sheets can be requested by a sailing scientist, if not, they should be discarded at the end of the expedition.- Pack up equipment being returned for repairs and give the Assistant Lab Officer the following information: IODP inventory number, value, weight, serial number, model number, vendor's name and country of manufacture.
- Give the Lab Officer a list for port purchases if any.
- Clean the lab and assigned area following the cleaning instruction listed in the Core Lab Handbook. Bring all the trash to the incinerator. Glass and sharps get disposed of in port call.
- Perform the end of Expedition maintenance as listed in the individual instrument use guide.
