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.
The data are stored on the AAD Storage Area Network (SAN), and as such are only directly accessible by AAD personnel. Currently a very large volume of data are stored (greater than 2 TB), hence ... distribution of these data are logistically feasible really only for people with access to the SAN.
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 (eg 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.
Note, that as of this date, all hydroacoustic data are up-to-date and current. It is envisaged that as more data are collected they will be added to this location on the SAN.
