| الوصف: | Maintenance and Update Frequency: asNeeded ; Statement: The Lord Howe Rise (LHR) 2D Seismic Survey, GA-0354/ KR1605 was acquired by Geoscience Australia on board the RV Kairei from the 17 March to 16 May 2016. The chief scientist on board was Dr Shuichi Kodaira (JAMSTEC) and Dr Scott Nichol (GA). The bathymetry dataset was acquired by JAMSTEC on board the RV Kairei and processed in the office by Michele Spinoccia, using CARIS HIPS & SIPS ver. 7.1.2. 1. First a vessel configuration file was created where the co-ordinates of the motion sensor and DGPS antenna and patch test offsets were recorded. 2. A new project was then created and the vessel configuration file was attached to the project file. 3. The raw swath sonar data, in raw.all format, for each line was then imported into the project and the vessel information assigned to the data. 4. The motion sensor, DGPS and heading data were then cleaned using a filter that averaged adjacent data to remove artefacts. 5. Different sound velocity profiles data for each block were attached to the corresponding raw swath sonar data files to correct the depths for changes in the speed of sound through the water column. 6. Then a new blank field area was defined that specified the geographic area of study and the co-ordinate system used. The co-ordinates for the study areas were WGS84 UTM-56S, 57S and 48S. 7. The data was cleaned by applying several filters that removed any remaining spikes in the bathymetry data using user defined threshold values. A visual inspection of the data for each line was then undertaken where artefacts and noisy data not removed by the filtering process were removed manually using Swath and subset editors modules of the Caris HIPS/SIPS software. 8. All the data for each bathymetric, motion sensor, DGPS, heading, tide and sound velocity profile data were merged to produce the final processed data file. A weighted grid of the processed data was then created for each Block. In GA the tide was applied to the grid to correct for tidal variations ... |
