The survey dataset, which includes metadata, was provided to the Australian Antarctic Data Centre by the Australian Hydrographic Office and is available for download from a Related URL in this metadata record. The survey was lead by LT A.J.Withers. The data are not suitable for navigation.

The data processing was done by the Royal Australian Navy's (RAN) Deployable Geospatial Support Team (DGST) and was provided to the Australian Antarctic Data Centre by the Australian Hydrographic Office. The dataset is titled HI513. The data was processed was collected on the following voyages: 1997/98 V2, V4, V6 1998/99 V1, V4, V5 2003/04 V1, V3, V7, V9 2004/05 V4, V5 2005/06 V2, V5 2006/07 V1, V2 2007/08 V1, V2, V3, V5, V6 2010/11 V3, V4, V5 2011/12 V1, V2, V3, VE1 The data has not been through the verification process for use in charts.

Royal Australian Navy soundings of approaches to Casey Station. This fair sheet, HI 189 V5/584 6610/1 scale 1:25 000, was hand digitised to capture soundings as point data. The data are not suitable for navigation. Bathymetric contours derived from these and other soundings are available from the metadata record with ID caseybathy_gis.

The data processing was done by the Royal Australian Navy's (RAN) Deployable Geospatial Support Team (DGST) and was provided to the Australian Antarctic Data Centre by the Australian Hydrographic Office. The dataset is titled HI534. The data processed was collected on the following voyages: 2012/13 voyages MS, 1, 2 and 3 The data has not been through the verification process for use in charts.

The data processing was done by the Royal Australian Navy's (RAN) Deployable Geospatial Support Team (DGST) and was provided to the Australian Antarctic Data Centre by the Australian Hydrographic Office. The dataset is titled HI483A because the processing was done on a 2010/11 voyage to Mawson and HI 483 was going to be a RAN survey at Mawson. The RAN survey wasn't feasible because of sea ice. The data processed (12KHz EDO 323HP echo sounder data) was collected on the following voyages: 2006/07 V2, V4, V6 2007/08 SIP, V3, V6 2008/09 V0, V1, V2, V3, V5 2009/10 V0, V1, V2, V3, V4, V5, V7 2010/11 Trials, V1, V2, V3, VE2, VMS All voyage data sets were processed in the following manner. As the Aurora Australis sails from either Hobart, Tasmania or Fremantle, Western Australia all the shallow water data files containing depths less then 200m around these ports were not processed and deleted. If the sea floor image was too hard to determine during the voyage either parts of day lines were not processed or the whole line deleted depending on the quality of the data. This is evident with some day *.CSV files containing a second or third file, these files had the same file name and were given a end character of _2 or _3. Unfortunately the program Echoview is meant to allow the user to span gaps when processing a line but more often than not, this was not the case. So if there was a requirement to a have gap in the daily file then usually a second file was created. Regularly throughout all voyages files were observed that had no GPS data associated with the depths. Any raw files without GPS data could not be processed, all these files have been deleted. Occasionally corrupt files were experienced, and these corrupt files have also been deleted. When the Aurora Australis was at anchor off an Antarctic Station these files too were deleted. With the various problems with the raw data files, no voyage has complete sounding data for the whole voyage. Some voyages have large sections of data missing, but unfortunately this data was not able to processed due to one of the above factors. All soundings were processed utilising the spheroid, WGS84 and only geographic co-ordinates have been determined. UTM grid co-ordinates were not calculated during the processing stages due to software limitations. Grid co-ordinates were not calculated for the final HTF files. Scripts were developed to apply depth water corrections, tide offsets if shallower than 200m of water and the layback of the sounder with respect to the Ashtech GPS. The processing of the data from 2007/08 V3, 2007/08 V6 and 2010/11 V3 was incomplete. Complete processing of the data from these voyages was done as part of HI513 which is described by the metadata record with ID AAD_voyage_soundings_HI513. The data has not been through the verification process for use in charts.

The RAN Australian Hydrographic Service conducted hydrographic survey HI350 at Mawson, January to March 2002. The survey area was north of the station between Williams Rocks and Parallactic Islands and also at Moller Bank. The survey dataset, which includes metadata, was provided to the Australian Antarctic Data Centre by the Australian Hydrographic Office and is available for download from a Related URL in this metadata record. The survey was lead by LCDR M.Pounder. The data are not suitable for navigation.

The RAN Australian Hydrographic Service conducted hydrographic survey HI514 at Mawson, February to March 2012. The areas surveyed were the entrance to Horseshoe Harbour and the western side of West Arm. There is also a single line of soundings east of Evans Island. The survey dataset, which includes the Report of Survey, was provided to the Australian Antarctic Data Centre by the Australian Hydrographic Office and is available for download (see a Related URL). The vertical datum of the soundings is Lowest Astronomical Tide, 0.83 metres below Mean Sea Level. The survey was lead by LT C.E.Diplock. The data are not suitable for navigation.
