This report describes the field survey carried out in Cockburn Sound, Western Australia by Geoscience Australia (GA) staff for the Coastal Geomorphology and Classification Subproject (CG) of the Coastal Water Habitat Mapping Project (CWHM). It documents the various sampling techniques and procedures used to collect surface and subsurface samples from the Sound; details of the vibracores and grab samples recovered and the proposed analyses to be performed on these samples.

Coastal CRC Coastal Water Habitat Mapping Project Coastal Geomorphology Subproject Report on the Geomorphology and Sediments of Cockburn Sound; Milestone Report CG4.04A. Darren Skene, David Ryan, Brendan Brooke and Lynda Radke. February 2005.
The focus of the Coastal Geomorphology (CG) subproject in Cockburn Sound is to examine the geomorphology of the sea bed, the spatial distribution of the various sediment types and the geomorphic evolution of this basin. These new geological data will be used to ground-truth acoustic data collected in Cockburn Sound, especially the multibeam backscatter data. This study will also provide a better understanding of the physical controls on the distribution of benthic habitats in the sound and substrate data that can be incorporated into a benthic habitat classification scheme.

Geoscience Australia. Record 2005/10. by Darren Skene, David Ryan, Brendan Brooke, Jodie Smith and Lynda Radke
This report examines the geomorphology and sediments of Cockburn Sound through the analysis of a suite of sediment grab samples and vibracores as well as existing data in published reports and scientific papers. The specific aims of this study are to: 1) Characterise the surface and sub-surface sediments and geochemistry of Cockburn Sound from a representative set of sediment grab samples and vibracores; and 2) Develop a conceptual model of the recent evolution of Cockburn Sound (spanning the Late Pleistocene and Holocene), based on the new and existing data.

Project CB: Benthic Biology and Habitat Mapping Milestone Report, December 2004.
This paper discusses the application of classic (terrestrial) sampling approaches to benthic habitat mapping, and the development of a sampling design for generating maps of seagrass species over a 100-km² area in Owen Anchorage, near Perth, Western Australia.
