Full description

Process Study 3 was undertaken between 03-05 October 2006 in North West Bay. Sediment traps were deployed and sediment samples taken at five sites in NWB. The primary aim was to investigate the composition of material being deposited to the sediments from the water column at these times and to compare this organic matter with that found in the sediments at the same sites. Additionally, we wished to see whether any organic matter of obvious fish farm origin could be detected. One sediment trap was deployed at each North West Bay (NWB) site in water varying in depth from 10 m (site 9) to 20 m (site 2). The trap sites were numbered 2, 4, 5, 7, and 9. Traps were deployed at their respective sites and left for at least one hour before the caps were removed in order to eliminate sediment re-suspended during deployment from entering the traps. The traps were left in place for 48 hours and then retrieved, capped and returned to Hobart for recovery of the samples. Each trap had 3 tubes, each of these tubes was split into three. One litre was taken and filtered for lipids using pre-weighed 47 mm GFF filters, one litre for pigments and the rest was split in two and stored in 500ml bottles, one for zooplankton analysis and the other for microalgal samples. Several filters were required to filter the lipid sample depending on the amount of particles in the tube. Selected filters were then analysed for lipid biomarkers. Organic matter from selected filters was also analysed for stable isotope 13C and 15 N values and carbon content. The contents of one tube from each trap was inspected for identification of zooplankton remains and faecal pellets using light microscopy. Sediments were collected at each of the above trap sites using a Wilco box corer.
