  • Give an orientation/safety procedures tour of the lab to the Chemists.
  • Meet with Chemists and find out their general goals and specific requests. If there are Microbiologists sailing make sure that these same protocols are done with them.
  • Divide up responsibilities among the Chemists for all shipboard analyses.
  • Have a meeting with the Chemists/Curator/EPM to go through sample plans.
  • Prepare sampling equipment and sample storage containers. Wash any necessary containers and prepare spikes if needed.
  • Prepare SampleMaster split template (water and cake splits).
  • Explain how to print sample labels.
  • Go over any and all MSDS sheets before working with any chemicals. Understand the risk of handling chemicals, especially if any hazardous chemicals will be used.
  • Print out the most recent copy of each instrument's User Guide so the Scientists can become familiar with each instrument's operation.


Prepare reagents
Put dates on all reagents made.

Prepare the following reagents according to the recipes in the user guides:. Remember to put dates on all reagents made.

  • Alkalinity/pH/chloride titrations
  • Coulometer
  • IC
  • ICP
  • SPEC

Check gas bottles

Check the pressure of the oxygen (ChemLab), helium and argon bottles (Tween Pallet Stores). Ensure the bottles are above 200psi; otherwise, swap them out with fresh bottles.

Supplies

IAPSO - . Store  Store it properly, as any evaporation will lead to increased salinity.
Necessary IW squeezing supplies:

  • 50mL plastic syringes (acid-washed).
  • 0.45µm Whatman disk filters.
  • Take four boxes of 9 cm #1 Whatman filters and soak them in a large beaker of DI water for ~2hours, then oven-dry at a low temperature (~50oC). When they are dry, store them in Ziploc bags near the Carver presses. Youmay You may need to do this again during the Expedition.
  • Obtain necessarycontainers necessary containers for IW sample splits. At the Scientist's request they may need to be rinsed with DI water/acid washed and dried..
  • Bags for squeeze cake splits and baked aluminum foil (if required .Bake bake at 500 C for 8 hours).

Clean spatulas and trays.Necessary catwalk sampling/sample processing supplies:

  • Headspace sampling tools and containers (vials, septa, crimper).
  • Gas void assemblies (50mL syringe and three-way stopcock, with male luer lock, attached to the core liner puncturing tool).

General lab supplies:

  • 10% HCl bath for general glass/plastic ware cleaning. 10% HNO3  
  • Paper towels
  • Kimwipes
  • Pipette tips
  • P-boxes (for sample storage; foam ampule holders for glass vial storage)
  • Gloves, various sizes
  • Boxes for cryovials
