Full description

Torres Strait is one of Australia's most important seaways in terms of shipping and defence. It forms Australia's only true international boundary. It is a shipping focal area and major seaway for Australian and foreign merchant vessels. This is the final report, in a series of four (four cruises represented in image), outlining the results of investigations into sandwave movement, currents and sedimentation in the main shipping channels of Torres Strait.

Lineage

Statement: Seismic data from the Estuary was of generally poor quality due to the rough sea conditions which prevailed during the survey. Only in a few locations were "glimpses" of deep reflectors obtained.
Statement: Surficial sediment grab samples were obtained at 122 stations using a Shipeck grab sampler. Navigation was obtained by Global Positioning system (GPS) which gave positions to a precision of +/- 0.001 minute (+/-1.8m). Cores were obtained at 11 locations using a piston corer. The currents were measured using an Aanderaa current meter. The temperature/salinity measurements were made with a Yeokal CTD.

Purpose
The aims of the project are: 1. To map the distribution of mobile bedforms (sandwaves/sand banks) and locations of sediment accumulation (thickness above bedrock) versus areas of scour in Torres Strait. 2. To identify the sediment's physical properties and assess them with respect to burial upon impact of objects. 3. To quantify current strengths along shipping channels. 4. On basis of the above, to quantify sediment transport and sedimentation (vertical accretion) rates in and adjacent to the shipping channels of Torres Strait.
