Geoscience Australia (GA) is proposing a marine survey to collect data to support a CO2 storage assessment in the Browse Basin, offshore Western Australia.
The overall research area (Figure A) is largely focussed on the Caswell Sub- basin of the Browse Basin including the outer portions of the Yampi and Leveque Shelves. The research area covers approximately 69,000 km2, including shelf, upper slope and basin floor areas in water depths ranging from approximately 100 to 1,000 m, bounded by the coordinates -15°S, -14.35°S, 124.9°E and 121.47°E. Data collection will occur within five regions within the research area, as shown in Figure B. (see EP Summary)
The survey timetable is now confirmed for the October – November 2014 period. The survey is proposed to be undertaken in two legs; the first leg would include AUV operations with the possibility of some seabed sampling (cores and grabs); the second leg would include ROV operations and seabed sampling (cores and grabs). The total time spent within the research area is expected to be 19 days, but may vary within the period according to site conditions.
