Brief description
This record describes the Acoustic Doppler Current Profiler (ADCP) data collected from the Marine National Facility RV Investigator voyage IN2021_V01, titled: "Quantifying krill abundance for krill monitoring and management off the Australian Antarctic Territory". The voyage took place from Hobart (TAS) to Hobart between January 29 and March 24, 2021. Both the RDI Ocean Surveyor 150kHz ADCP and the RDI Ocean Surveyor 75kHz ADCP were run in narrowband for transit to and from the survey area. During survey transects the OS150 was used. Data was collected using UHDAS and post-processed using CODAS. Internal triggering was used for the transits to and from the survey site only. When run on transect lines or during target trawling, triggering was performed via KSYNC, synchronised to the EK80 with a ping frequency between 1 and 2.5 seconds. Please see the voyage computing and electronics report for more details regarding operation. This dataset was processed and then archived within the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC) in Hobart.Lineage
