HOME ICES Trial Survey and intercalibration on Passive Sampling 2006-2007 Initiative from WGMS and MCWG Focal point Foppe Smedes (RIKZ The Netherlands) Last updated 28 September 2006 Exercise do list
Step	Do what
Receival material	See how material and what material was packed on slideshow (7Mb) Check the content (frame nr, sheetholder nr and bottle nr) with info here
Store	Sheets and bottles tobe stored in dark and freezer
Watersampling	READ PROTOCOL CAREFULLY Expose 2 samplers, leave reference in the freezer See video on how to mount the sheets Record water and air temperature salinity. Perform you musselprogram as designed by yourself (If you received a mussel basket these can only be placed in the frame from beneath) Any other parrallel activities After exposure clean and store sheets in freezer. Send one set of exposed sheets for reference lab and material back to RIKZ. (also send one reference back!! If two were sent to you) Analyse your sheets (see protocol) Analyse mussels Report your results
Sediment sampling	READ PROTOCOL CAREFULLY Record depth, sampling method and salinity. For weight of the bottles see here Expose 2 bottles, leave reference in the freezer Perform any parrallel activities After exposure wash out sediment and store bottle in freezer. Send one exposed bottle to reference lab (also send one reference back!! If two were sent to you) Analyse your bottles (see protocol) Analyse total sediment including CORG Report your results
PRCs	Target list nad PRCs are given here Dissolve PRC standard in vial (for approximate amounts see here). Inject and identify retention times of compounds and add them to your calibration table with selected response factor. Note that the ratio between reference and sample is relevant and not the absolute concentration. See protocol for more info
