Abstract

The Petrel Sub-basin Marine Environmental Survey GA-0335, (SOL5463) was acquired by the RV Solander during May 2012 as part of the Commonwealth Government's National Low Emission Coal Initiative (NLECI). The survey was undertaken as a collaboration between the Australian Institute of Marine Science (AIMS) and GA. The purpose was to acquire geophysical and biophysical data on shallow (less then 100m water depth) seabed environments within two targeted areas in the Petrel Sub-basin to support investigation for CO2 storage potential in these areas.

Lineage

The backscatter data were processed using CMST-GA MB Process v12.05.07 software. The fully processed backscatter strengths were corrected for transmission loss and insonification area. The process within the toolbox also involved removal of the system transmission loss, removal of the system model, calculation of the incidence angle and removal of the angular dependence. The grid values are basically the average values of the processed backscatter point data within each grid cell of predefined size, normalised to the backscatter strength at an angle of 25 degrees. The following commands were used to process and generate the grids in *.bat mode: cd e:\working_data\solander\sol5463_bonaparte_gulf_2012_reproc\proc reprocess -Ie:/working_data/solander/sol5463_bonaparte_gulf_2012/filelist_sol5463_leg1_sh547.txt -fe:/working_data/solander/sol5463_bonaparte_gulf_2012_grid1 -A25 -L100 -M2 -dwgs84 -z52 -K1 -V4 -S1 -Be:/working_data/calib/SingleHead547o_new.bpt reprocess -Ie:/working_data/solander/sol5463_bonaparte_gulf_2012/filelist_sol5463_leg1_sh548a.txt -fe:/working_data/solander/sol5463_bonaparte_gulf_2012_grid1 -A25 -L100 -M2 -dwgs84 -z52 -K1 -V4 -S1 -Be:/working_data/calib/SingleHead548n_new.bpt -b-0.55 reprocess -Ie:/working_data/solander/sol5463_bonaparte_gulf_2012/filelist_sol5463_leg1_sh548b.txt -fe:/working_data/solander/sol5463_bonaparte_gulf_2012_grid1 -A25 -L100 -M2 -dwgs84 -z52 -K1 -V4 -S1 -Be:/working_data/calib/SingleHead548n_new.bpt -b4.42 reprocess -Ie:/working_data/solander/sol5463_bonaparte_gulf_2012/filelist_sol5463_leg1_sh548c.txt -fe:/working_data/solander/sol5463_bonaparte_gulf_2012_grid1 -A25 -L100 -M2 -dwgs84 -z52 -K1 -V4 -S1 -Be:/working_data/calib/SingleHead548n_new.bpt -b-0.55 reprocess -Ie:/working_data/solander/sol5463_bonaparte_gulf_2012/filelist_sol5463_leg2_sh548_rentPU.txt -fe:/working_data/solander/sol5463_bonaparte_gulf_2012_grid1 -A25 -L100 -M2 -dwgs84 -z52 -K1 -V4 -S1 -Be:/working_data/calib/SingleHead548n_new.bpt -b0.87 cd e:\working_data\solander\sol5463_bonaparte_gulf_2012_grid1\proc LargeGrid -Ie:/working_data/solander/sol5463_bonaparte_gulf_2012/filelist_grid1.txt sscecomp 2 boundary atile -R474710/507490/8571470/8607670 -Oe:/working_data/solander/sol5463_bonaparte_gulf_2012_grid1/grd/bksct_grid1_reprocA25_final_2m.asc LargeGrid -Ie:/working_data/solander/sol5463_bonaparte_gulf_2012/filelist_grid1.txt sscecomp 5 boundary atile -R474710/507490/8571470/8607670 -Oe:/working_data/solander/sol5463_bonaparte_gulf_2012_grid1/grd/bksct_grid1_reprocA25_final_5m.asc LargeGrid -Ie:/working_data/solander/sol5463_bonaparte_gulf_2012/filelist_grid2.txt sscecomp 2 boundary atile -R518400/536050/8619200/8640200 -Oe:/working_data/solander/sol5463_bonaparte_gulf_2012_grid1/grd/bksct_grid2_reprocA25_final_2m.asc LargeGrid -Ie:/working_data/solander/sol5463_bonaparte_gulf_2012/filelist_grid2.txt sscecomp 5 boundary atile -R518400/536050/8619200/8640200 -Oe:/working_data/solander/sol5463_bonaparte_gulf_2012_grid1/grd/bksct_grid2_reprocA25_final_5m.asc
