II. PORT CALL - Start of an Expedition (Port call can be sup to 5 days)

  • Find your room and bunk assignment, drop your luggage off.
  • Go to your lab and begin cross over with the off going technicians.
  • Read the lab report from the previous Expedition and discuss any changes in equipment status or procedures. This can be found on Confluence XRD Lab Notebook.
  • Attend introductory meeting with all IODP staff or any other safety or training meetings.
  • Assist with loading/unloading of cores, freight and other tasks as directed by the Lab Officer (LO) or Assistant Lab Officer (ALO).
  • Unpack all oncoming freight and distribute them accordingly
  • Verify physical counts on priority #1 inventory items for XRD, ICP Prep, and pXRF. Bring to LO/ALO's immediate attention if any item is short on quantity.
  • Read the XRD manuals for instruments you will be using.
  • Collect and remove all trash from your lab before sailing. There will be a trash container not he dock side, ask ALOs for confirmation.

III. SITE PREPARATION - Prior to arrival on site and core on deck

  • Check water level and temperature of Haskris chiller. Ensure filter is clean.
  • Before running the Bruker D4, initialize the sample changer from XRD Commander Program or if from a complete shutdown initialize sample changer first using D4 tools, then initialize using Commander, then run 'tube conditioning program in D4 Tools. (Instructions are in the XRD Bruker Manual).
  • Run QAQC Standard in D4 as detailed in manual.
  • Coordinate a work area in the fume hood with the chem tech and make sure there is a 10% Nitric bath available for cleaning quartz and platinum crucibles.
  • Familiarize yourself with the expedition prospectus and ascertain a likely number of ICP, XRD, and pXRF samples that can be processed. Discuss sampling with Curator and applicable scientists. The core lab is your primary duty and x-ray must come secondary to that unless arrangements are made with the Lab Officer to meet specific objectives. Scientists should be made aware of this and that it is not reasonable to expect high resolution on a high recovery expedition.
  • Provide training to scientists on using XRD software
  • Provide training to scientists on hand held XRF in instrument operation, sample preparation, and data upload/download procedure
  • Provide safety training to scientists who uses hand held XRF. Check out and assign dosimeter ring to individual scientist. Ensure they understand all safety concern and sign required document.
