Process Study 2 was undertaken between 20-22 September 2005 in the Huon Estuary offshore from Hideaway Bay. During this Process Study, two sediment traps were deployed at each of two sites (near sites P3 and P4 from the spatial survey) on the bottom for 24 hours.Prior to the deployment of the traps surface sediment samples were collected with a benthic grab from each site. Each sediment trap consisted of three collection tubes, material from each tube was filtered on 47 mm GFF filters, with several filters required to filter all of the particualte matter from each tube. Combined filters from each of two tubes labeled A and B (typically 3 filters for each tube) were extracted for lipid analysis. Tube C was used either for isotopes or Fauna indent.

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.

This record describes sediment trap sample data collected as part of the 1991-1993 Tasmanian Slope Trophodynamics Study undertaken by CSIRO Division of Fisheries. 2 moored sediment trap arrays with <21 individual traps were deployed on a single date in November 1992 at two depths (305 and 952 m), allowed to remain open for various times, and retrieved in April 1993. Free-floating traps were also deployed for approx. 24 hr and 48 hr in November 1992 and April 1993, respectively. On recovery, samples were analysed for weight dry weight, chemical analysis for carbonate, reactive phosphorus, total carbon, total nitrogen, biogenic opal, and phytoplankton pigments, and sub-samples were also taken for SEM (scanning electron microscope) identification of phytoplankton species.

This record is an overview entry for biological data collected on Southern Surveyor cruise SS 01/95, a part of the JGOFS Southern Ocean Processes study. This cruise took place in the Southern Ocean during 14 January - 2 February 1995, under the leadership of Brian Griffiths. Biological data collected on this cruise include measurements of in-situ optical properties, including spectral absorption and upwelling and down-welling spectral irradiance in the sub-tropical convergence zone (STCZ). Samples for pigment analysis, in-situ zooplankton grazing, samples from sediment traps, zooplankton and phytoplankton samples. Measurements of chlorophyll-a and other pigments, primary production, cyanobacteria, and lipids. Isotopic composition of phytoplankton carbon and nitrogen. Acoustic data to describe the distribution and movement of biological organisms.

Individual data types - which may span several cruises - will be indexed separately within this metadata system in due course.

This record is an overview entry for biological data collected on Southern Surveyor cruise SS 11/95, a part of the JGOFS Southern Ocean Processes study. This cruise took place in the Southern Ocean during 15 November - 7 December 1995, under the leadership of Bronte Tilbrook. Biological data include measurements of in-situ optical properties, including spectral absorption and upwelling and down-welling spectral irradiance in different water masses west of Tasmania. DMS, and DMSP measurements. Dissolved and particulate organic carbon and isotopic composition. Radon measurements, zooplankton and larval fish abundance, nekton biomass estimates using both midwater trawls and acoustic backscatter measurements. Atmospheric chemistry and cloud measurements were also undertaken as part of the ACE-1 International Global Atmospheric Chemistry project.
