The data are available in csv format and the raw SIMRAD format. In the csv files bathymetric data is in the WTR_DEPTH_M column. Some voyages will not have bathymetric data associated with them. The csv data may have been quality checked. Most of the underway data was quality checked ('dot zapped') up to and including voyage 4 2003/04. Data quality reports are available by searching at http://data.aad.gov.au/aadc/voyages/ Other than on Marine Science voyages, the Aurora Australis bathymetric data gathering procedures prior to about 2000 were not checked during the voyage. The echo sounder was turned on in Hobart and if it stopped working during the voyage, then there was no one to get it going again. Bathymetric data from these voyages that has been processed by the Royal Australian Navy is available via other metadata records linked to the parent record with ID AAD_voyage_soundings. {"type": "Polygon", "coordinates": [[[30.0, -70.0], [170.0, -70.0], [170.0, -42.0], [30.0, -42.0], [30.0, -70.0]]]} 30.0 170.0 -70.0 -42.0 AMD AMD/AU Bathymetry CEOS CONTINENT > ANTARCTICA EARTH SCIENCE > OCEANS > BATHYMETRY/SEAFLOOR TOPOGRAPHY EARTH SCIENCE > OCEANS > BATHYMETRY/SEAFLOOR TOPOGRAPHY > BATHYMETRY EARTH SCIENCE > OCEANS > BATHYMETRY/SEAFLOOR TOPOGRAPHY > SEAFLOOR TOPOGRAPHY EARTH SCIENCE > OCEANS > BATHYMETRY/SEAFLOOR TOPOGRAPHY > WATER DEPTH ECHO SOUNDERS GEOGRAPHIC REGION > POLAR OCEAN > SOUTHERN OCEAN OCEAN > SOUTHERN OCEAN > HEARD AND MCDONALD ISLANDS OCEAN > SOUTHERN OCEAN > MACQUARIE ISLAND R/V AA > R/V Aurora Australis SHIPS Soundings Water Depth GET DATA documentDigital Download data in csv format HTML GET DATA documentDigital Request data in raw SIMRAD format for voyages beginning in 1990 to 1994 HTML GET DATA documentDigital Request data in raw SIMRAD format for voyages beginning in 1995 to 1999 HTML GET DATA documentDigital Request data in raw SIMRAD format for voyages beginning in 2000 to 2002 HTML GET DATA documentDigital Request data in raw SIMRAD format for voyages beginning in 2003 HTML GET DATA documentDigital Request data in raw SIMRAD format for voyages beginning in 2004 HTML GET DATA documentDigital Request data in raw SIMRAD format for voyages beginning in 2005 HTML GET DATA documentDigital Request data in raw SIMRAD format for 2011/12 voyages HTML VIEW RELATED INFORMATION documentDigital Citation reference for this metadata record and dataset HTML Creative Commons by Attribution logo documentDigital PNG
