Progress Code: completed Statement: Zooplankton were collected with an umbrella net deployed through an ice hole. Water samples were collected with a kemmerer bottle. The sediment traps were designed and constructed at the Australian Antarctic Division. Chlorophyll a samples were extracted and run on a UV-Vis spectrophotometer. Particulate organic carbon samples were analysed with a CHN analyser. Zooplankton, phytoplankton and sediment trap samples were all examined with various types of microscopy. See the documentation in the download file(s) for further information. The files provided in the download are quite old, and as such some of them were unable to be opened when they were archived. These files are still included as part of the download though. This dataset contains samples collected at O'Gorman Rocks and Ellis Fjord near Davis station from December 1997 to March 1998. Depth-stratified zooplankton samples were obtained for determination of zooplankton abundance and biomass. Water samples were collected for the determination of chlorophyll a concentration, protist identification and abundance, and the concentration of particulate and dissolved organic carbon. Sediment trap material was collected for the analysis of faecal pellets (identification and CHN analyses), protist identification and abundance, and the measurement of particulate organic carbon concentration. Zooplankton grazing experiments were performed in the laboratory at Davis station and zooplankton were also collected for CHN analyses. Data from this project arose from projects ASAC 963 and ASAC 2229.
