  1. INTERREG III: STARDUST January 2003- September 2003 VLIZ Lille, 18/09/03

  2. First joint sampling expedition Rupel River Sampling site • Intertidal flat: easily sampled at low tide • expect relatively contaminated sediments • organic rich sediments Lille, 18/09/03

  3. Porewater analysis by DGT/DET/coring Aim • Interlaboratory intercomparison • identify problems • establish protocol for further work Methods used • Coring by hand • porewater separation: on field USTL, in lab VUB • cores for DGT and DET transported to the lab • DGT and DET probes deployed at room temperature for 24h (2 cores) • USTL: DGT diffusive gels 0.8 and 1.2mm • in same core • VUB: DGT diffusive gels 0.8 and 0.8mm • in different cores Lille, 18/09/03
