Sampling

Water (Niskin), SPM, sediment (Van Veen and box corer), deployment of tripod with passive samplers anchored

Report

A tripod was deployed on Monday 14/03/2016 13h21 (GMT) at MOW1(51°N 21.609’, 3°E 08.0806’). On the tripod two cages with two types of passive samplers were attached. Pre–extracted non-spiked silicone sheets (PDMS sheets) were attached to a cage for Ghent University. Pre–extracted and PRC-spiked silicone sheets were attached for OD Nature. A sediment trap (Technicap PPS 4/3) and two sediment traps (experimental design from OD Nature) were deployed for grain size analysis and chemical extraction. In addition divinylbenzene (DVB) based passive samplers were attached to the cage deployed with the tripod. After recovery, all passive samplers deployed for the NewSTHEPS project will be used for chemical analysis or bioassays. From the buoy above the tripod, a smaller buoy with a passive sampler cage (DGT) was attached for trace metal sampling in the surface water. Water samples were taken for turbidity measurements, SPM concentration, chlorophyll, POC/PON concentration and salinity measurements in OD Nature. Furthermore Niskin bottles were used to take water samples at approximately 2 meters depth for chemical analysis for the NewSTHEPS project. The samples were filtered through 1.0 µm GF/B Whatmann glass fiber filters or Durapore 0.45 μm PVDF filter under vacuum before storage at 4°C. Filtered SPM were stored in deep freeze for carbon analysis or at 4°C for trace metal content. Sediment sampling using a Van Veen grab was taken for further extraction of the sediment and chemical analysis in OD Nature and from two Box-corers were retrieved three sediment cores of approximately 20 cm.
