This record describes the Acoustic Doppler Current Profiler (ADCP) data collected from the Marine National Facility RV Investigator voyage IN2024_V05, titled: "Multi-year: Untangling the causes of change over 25 years in the southeast marine ecosystem (SEA-MES Voyage 3)." The voyage took place between November 13, 2024 and December 12, 2024 (AEST), departing from Hobart and returning to Hobart.
The ADCP was run for most of the voyage, though it was turned off when EK80 surveys were being performed to avoid creating interference in the EK80 data. As this was a fisheries voyage, the EK80 was used extensively and the ADCPs were not acquiring for long periods throughout the voyage.
ADCP data were collected using the University of Hawaii Data Acquisition System (UHDAS) and post-processed using the Common Ocean Data Access System (CODAS). Documentation for these systems can be found in (Hummon, 2009-2021).
The RDI Ocean Surveyor 150kHz ADCP, RDI Ocean Surveyor 75kHz ADCP and RDI Ocean Surveyor 38kHz ADCP were run in narrowband mode.
Internal triggering was used.
The drop keel was set at 2 metres below the hull for the duration of the voyage. The nominal transducer depth is set to 6 metres, any additional changes will need to be applied by the user if they believe it is required.
Bottom tracking was run for an hour of the voyage on the OS150nb to aid in calibrations.

This dataset was processed (quality-controlled), and then archived by the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC).
