Summary:Maintenance and Update Frequency: asNeeded Credit Australian Antarctic Division (AAD) Credit Australian National Antarctic Research Expeditions (including ASAC proposals #2256 and #1156) Credit CSIRO Division of Marine Research's Climate Oceans and Climate Program Credit Woods Hole Oceanographic Institution Credit Australia’s Integrated Marine Observing System (IMOS) is enabled by the National Collaborative Research Infrastructure Strategy (NCRIS). It is operated by a consortium of institutions as an unincorporated joint venture, with the University of Tasmania as Lead Agent. This report details the sites, moorings, data from the current meters and sediment traps, and results of analyses performed on the collected sediment trap material between 1997 and 1998. The quality controlled datasets are publicly available via the AODN Data Portal. This report should be consulted when using the data. The SAZ project organised by the Antarctic CRC has a continuing program of moored sinking particle trap studies in the Sub-Antarctic and Polar Frontal zones southwest of Tasmania along 140 °E. The first deployment obtained weekly or higher resolution samples through the austral summer from September 1997 through February 1998 at three locations: the central Sub-Antarctic Zone (47°S, traps at 1000, 2000, and 3800m depth), the Sub-Antarctic Front (51 °S, 1 trap at 3300m ) and above the Southeast Indian Ridge in the Polar Frontal Zone (54 °S, 2 traps at 800 and 1500m). The particles were analysed for total mass, inorganic carbon, total carbon, nitrogen, silicon, and aluminium. Hence values for organic carbon, biogenic silica, and lithogenics were obtained, and the mass fluxes calculated.
