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
Porewater analysis by DGT/DET/coring•Interlaboratory intercomparison•identify problems•establish protocol for further work
Aim
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
