Standard Operating Procedure – Physical Properties Lab

The Physical Properties technician shares his/her duties between the Core Lab and the Physical Properties Lab. For details on the Core Lab duties, refer to the Core Lab SOP.

I. PRE EXPEDITION

  • See General JRSO Technician SOP
  • Pre-weigh sample vials for MAD samples (shore based techs only). Find out and estimated quantity is needed for the up coming expedition, and ensure sufficient quantity of pre-weighed vials are available onboard.

II. PORT CALL - Start of an Expedition

  • 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, SHMSL, ThermCon, Gantry, MAD, NGR), 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

Site Preparation

  • 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.

...

  • Instruct Scientists on Lab Procedures. PRACTICE, PRACTICE, PRACTICE before expedition starts – from sampling to MAD to Vp (discrete and continuous) measurements, and everything else.

IV. DURING CORING OPERATIONS

  • Receive core and assist as needed in the core lab
  • Ensure that data is being correctly uploaded to the LIMS.
  • Check QAQC of all instruments as calibrated as needed.
  • Dry out/replace silica desiccant (MAD station) as needed.

V. DURING TRANSITS

  • Keep Lab Clean and Orderly
  • Continue processing cores through the lab as described above

VI. DURING EXPEDITION

  • All staff are expected to perform shipboard duties as assigned by Lab Office as priority over other projects.
  • All staff are expected to report to work 5 minutes prior to the shift change time to cross-over with the off going staff. You should be ready to "work" when you come on shift.
  • All staff are expected to have their breakfast prior to coming on shift, have their dinner (supper) after shift ends and relieved from the oncoming staff. Lunch is the only meal eaten during the shift.
  • Although break time onboard is scheduled at 3am, 9am, 3pm, and 9pm, due to our responsibilities, all staff are expected to adjust their break time according to "core-on-deck" schedules. A 15 minutes break time is reasonable.
  • All staff on shift are expected to be available for the entire 12 hours. You must respond to a call or a page. If you will be working in an area where no speaker or phone available, it is recommended that you notify ALO or your fellow staff with your whereabouts.
  • All staff are expected to follow safety regulations at all time.
  • Wearing headphones with music during shift is highly discouraged due to safety reasons.
  • Maintain inventory by randomly performing physical counts. Notify the ALOs if any quantity discrepancy or unusual high usage occurred.
  • Familiar yourself with the storeroom inventory check-in, check-out system

VII. END OF EXPEDITION ACTIVITIES

  • 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.
  • Pack up all log sheets and give them to ALO for shipping back to database group on shore.
  • 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.
