Abstract:

This report describes the properties of sediments off Cairns, North Queensland, obtained from samples gathered during trials with A.M.s Brolga and Bermagui in August 1996. These data were obtained in a survey of seabed properties to determine suitable sites and transects for TTCP trials of environmental reconnaissance techniques, which occurred in AprilMay 1997. The data are relevant to mine burial, acoustic propagation and high frequency reverberation, all important factors in mine warfare. The results form a worthwhile addition to the Mine Warfare Systems Centre and Australian Oceanographic Data Centre data bases, especially as the Cairns area appears to be typical of much of North Queenslands eastern coast and the data herein include much information on sediment shear and bearing strengths, parameters which are critical to impact burial but which are rarely measured.
