This Milestone Report documents the results of the analysis of sediment samples collected during the survey of Sydney Harbour in August, 2003. The samples were collected by Geoscience Australia (GA) and Defence Science and Technology Organisation (DSTO). The sediment sampling programme was undertaken as part of the coastal geomorphology and classification sub-project of the Coastal CRC - Coastal Water Habitat Mapping Project. Samples were collected to assess the physical character of the sediments and map their distribution for comparison with the geomorphology of the estuary floor using new and existing swath bathymetry data.

The analysis of the sediment samples will be used to groundtruth the areas surveyed with the Coastal CRC's Reson SeaBat 8125 multibeam sonar mapping system. Approximately one third of the targeted area was covered by the Seabat 8125 in the first survey, due to problems with the survey boat. The remaining area will be surveyed in the second Sydney Harbour survey, which is planned for September/October 2004. The sediment data will be used to assess how the physical properties of the benthos vary spatially and how they influence acoustic backscatter waveforms to classify benthic habitats. The study builds upon the existing knowledge of the geomorphology of the seabed in Sydney Harbour.

The report also discusses issues of interpretation and equipment selection for the toolkit as well as other completed work.
