Hydroacoustics data obtained from Australian Antarctic Division voyages from 1993 to 2004. Voyages were made to various locations within the Southern Ocean. Data are stored on 14 hard disks, 1 CD-R and 1 DVD-R for archiving in a secure storage area.
A catalogue describing what data are held on each media is available for download from the provided URL.
The hard disks in the archive box are labelled as 'Status 1'.
These data were 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.
Note - all Australian Antarctic Division hydroacoustic data have now been collated on the AAD Storage Area Network (SAN). This digital collection supersedes the collection of hard disks, and comprises (as of now) the sum total of all AAD hydroacoustic data. Ideally as more hydroacoustic data are collected by AAD vessels, they will be added to the SAN. See the metadata record entitled "Hydroacoustic data collected from Southern Ocean Cruises by the Australian Antarctic Division" for more information.
