Hydroacoustic data collected from Southern Ocean Cruises by the Australian Antarctic Division

The Australian Antarctic Division (AAD) has been collecting hydroacoustic data from its ocean going vessels for a number of years. This collection represents all hydroacoustic data gathered since 1990.As well as data, a large amount of documentation is provided - including methods used to collect these data, as well as any products resulting from these data (e.g. papers, reports, etc).In the past, these data have been collected under several ASAC projects, ASAC 357 (Hydroacoustic Determination of the Abundance and Distribution of Krill in the Region of Prydz Bay, Antarctica) and ASAC 1250 (Krill flux, acoustic methodology and penguin foraging - an integrated study) - ASAC_357 and ASAC_1250.As of 2019-12-19 the folders present in the acoustics data directory are:1990-05_Aurora-Australis_HIMS1991-01_Aurora-Australis_AAMBER21991-10_Aurora-Australis_WOCE911992-01_Aurora-Australis_Calibration_Great-Taylors-Bay1993-01_Aurora-Australis_Calibration_Port-Arthur1993-01_Aurora-Australis_KROCK1993-02_Aurora-Australis_Calibration_Mawson1993-03_Aurora-Australis_WOES-WORSE1993-08_Aurora-Australis_Calibration_Port-Arthur1993-08_Aurora-Australis_THIRST1994-01_Aurora-Australis_SHAM1994-12_Aurora-Australis_WOCET1995-02_Aurora-Australis_Calibration_Casey1995-07_Aurora-Australis_HI-HO_HI-HO1996-01_Aurora-Australis_BROKE1996-01_Aurora-Australis_Calibration_Port-Arthur1996-02_Aurora-Australis_Calibration_Casey1996-08_Aurora-Australis_WASTE1997-01_Aurora-Australis_BRAD1997-09_Aurora-Australis_ON-ICE1997-09_Aurora-Australis_WANDER1997-11_Aurora-Australis_SEXY1997-11_Aurora-Australis_V31997-98-050_V51998-02_Aurora-Australis_SNARK1998-04_Aurora-Australis_PICCIES1998-07_Aurora-Australis_FIRE-and-ICE1998-09_Aurora-Australis_V21998-10_Aurora-Australis_SEXYII1999-01_Aurora-Australis_V51999-03_Aurora-Australis_STAY1999-07_Aurora-Australis_Calibration_Port-Arthur1999-07_Aurora-Australis_IDIOTS1999-10_Aurora-Australis_V21999-11_Aurora-Australis_V42000-01_Aurora-Australis_V52000-02_Aurora-Australis_V62000-10_Aurora-Australis_Calibration_Port-Arthur2000-11_Aurora-Australis_V12000-12_Aurora-Australis_KACTAS2001-01_Aurora-Australis_Calibration_Mawson2001-02_Aurora-Australis_Calibration_Davis2001-10_Aurora-Australis_CLIVAR2002-01_Aurora-Australis_LOSS2002-09_Aurora-Australis_V12002-10_Aurora-Australis_Calibration_Port-Arthur2003-01_Aurora-Australis_KAOS2003-02_Aurora-Australis_Calibration_Mawson2003-03_Aurora-Australis_Off-charter2003-09_Aurora-Australis_ARISE2003-09_Aurora-Australis_Calibration_NW-Bay2003-11_Aurora-Australis_V22003-12_Aurora-Australis_HIPPIES2004-02_Aurora-Australis_V72004-05_AAD_Lab-testing2004-06_Aurora-Australis_Off-charter2004-102004-10_Aurora-Australis_Calibration_NW-Bay2004-10_Aurora-Australis_V12004-11_Aurora-Australis_V22004-11_Howard-Burton_NW-Bay-testing2004-12_Aurora-Australis_ORCKA2004-12_Howard-Burton_NW-Bay-testing2005-02_Aurora-Australis_V52005-04_Howard-Burton_Bruny-Island-testing2005-11_Aurora-Australis_Calibration_Port-Arthur2005-11_Aurora-Australis_V22006-01_Aurora-Australis_BROKE-West2006-02_Aurora-Australis_Calibration_Mawson2006-03_Aurora-Australis_V52006-09_Aurora-Australis_V12006-12_Aurora-Australis_V22007-01_Aurora-Australis_SAZ-SENSE2007-04_Aurora-Australis_V52007-08_Aurora-Australis_SIPEX2011_10_20_Aurora_Calibration200910_Aurora-Australis_BathymetryProcessing201803_tankExperiments20150102_Tangaroa200708030_Aurora-Australis_V3_CEAMARC200708040_Aurora-Australis_V4200708060_Aurora-Australis_V6_CASO200809000_Aurora-Australis_VTrials200809010_Aurora-Australis_V1200809020_Aurora-Australis_V2200809030_Aurora-Australis_V3200809050_Aurora-Australis_V5200910000_Aurora-Australis_VTrials200910010_Aurora-Australis_V1200910020_Aurora-Australis_V2200910030_Aurora-Australis_V3200910040_Aurora-Australis_V4200910050_Aurora-Australis_V5200910070_Aurora-Australis_VE1201011000_Aurora-Australis_VTrials201011002_Aurora-Australis_VE2201011010_Aurora-Australis_V1201011020_Aurora-Australis_V2201011021_Aurora-Australis_VMS201011030_Aurora-Australis_V3201011040_Aurora-Australis_V4201011050_Aurora-Australis_V5201112000_Aurora-Australis_VTrials201112001_Aurora-Australis_VE1201112010_Aurora-Australis_V1201112020_Aurora-Australis_V2201112030_Aurora-Australis_V3201112040_Aurora-Australis_V4201112050_Aurora-Australis_V5201112060_Aurora-Australis_V6201213000_Aurora-Australis_VTrials201213001_Aurora-Australis_VMS_SIPEX201213010_Aurora-Australis_V1201213020_Aurora-Australis_V2201213020_Aurora-Australis_V3201213040_Aurora-Australis_V4201314010_Aurora-Australis_V1201314020_Aurora-Australis_V2201314040_Aurora-Australis_V4201314060_Aurora-Australis_V6201415000_AuroraAustralis-Trials201415010-AuroraAustralis_V1201415020_AuroraAustralis_V2201415030_AuroraAustralis_V3201415040_AuroraAustralis_V4201516000-AuroraAustralis_VTrials201516010_AuroraAustralis_V1201516020_AuroraAustralis_V2201516030-AuroraAustralis_V3201617010-AuroraAustralis_V1201617020-AuroraAustralis_V2201617030-AuroraAustralis_V3201617040-AuroraAustralis_V4201718010-AuroraAustralis_V1201718020-AuroraAustralis_V2201718030-AuroraAustralis_V3201718040-AuroraAustralis_V4201819010-AuroraAustralis_V1201819020-AuroraAustralis_V2201819030-AuroraAustralis_V3201819040-AuroraAustralis_V4201920000-AuroraAustralis_VTrials201920010-AuroraAustralis_V1201920011-AuroraAustralis_VMI
