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.
...
- Balance: Carried out while in port with the reference mass standards.
- Pycnometer: Calibrate using the MAD program with the reference sphere standards. A good reference for re-calibration is when the calibration verification drifts by about > +/- 1.5% of the actual value.
2. Turn on oven (105ºC).
3. Make sure that the containers and sampling tools are available to the scientists.
- Instruct Scientists on Lab Procedures. PRACTICE, PRACTICE, PRACTICE before expedition starts – from sampling to MAD to Vp (discrete and continuous) measurements, and everything else.
