Brief description AUV Sirius (IMOS Platform code: SIRIUS) was deployed near Batemans Bay in New South Wales, November 2011. Dives in New South Wales were coordinated around existing BRUVs locations maintained by DECCW and the Batemans' Bay MPA. Broad grids and dense patch surveys were completed at each site, although an issue with the vessel, a fault with the vehicle’s battery and weather meant that not all sites were completed at Port Stephens. We are looking to complete these in early 2011.The 2010/11 period has predominantly been spent establishing benthic reference sites at numerous sites around Australia using the AUV. The SIRIUS overtook 13 dives and travelled for 36 kms. 79296 stereo pairs images were captured every around each 40cm at an average altitude of 2.2m. At the conclusion of the trip the dataset included over 1TB of geotiff imagery, multibeam, AUV tracks, 3D textured meshes and hydrographical data (CDOM, Salinity, Temperature, . The dive reports from this campaign summarise AUV activity during each dive.
Lineage Maintenance and Update Frequency: asNeeded
Lineage Statement: The files in this folder form part of the data 'product' from the IMOS AUV Facility Sirius AUV operated by the University of Sydney's Australian Centre for Field Robotics. The directory contains a number of different file types. These are listed below. The 'product' from each dive is contained in it's own named folder. *all_reports folder:- This folder contains the PDF short dive report files, one for each of the dives. These contain some summary graphs and sample images. *per_dive folder:- -> i*_gtif (contains geotif versions of all images). -> i*_subsampN (subsampled geotif images (one in N, and a csv of locations). -> hydro_netcdf (*.nc files, netcdf files containing CT and ecopuck data). -> track_files (dive track in csv, kml and arcgis shape file format). -> mesh (3D reconstuction of the dive, needs OSG viewer software). -> multibeam (a number of different versions of the multibeam product). *.gsf: Navigated and automatically cleaned swath bathymetry with raw intensity data. Format specification 121 (SAIC Generic Sensor Format) in mbsystem. *.grd: Gridded bathymetry. NetCDF format as used with GMT. Use grdinfo to determine resolution and projection. *.grd.pdf: Plotted gridded bathymetry (local northings and eastings) acrobat PDF format. Windows Viewers folder:- This folder contains a copy of gqview a windows image viewer that is able to view the geotiffs. These are standard tiff's but with jpg compression, and the regular windos viewer will not open. Other more capable windows programs including AcDsee (spelling???) also work. Ultimately there should be a copy of the windows viewer for the meshes but this is not yet here. Acknowledgement:- "Data was sourced from the Integrated Marine Observing System (IMOS).

Distribution Statement:- "AUV data may be reused, provided that related metadata explaining the data has been reviewed by the user, and the data is appropriately acknowledged. Data products and services from IMOS are provided "as is" without any warranty as to fitness for a particular purpose".
