This record describes the Acoustic Doppler Current Profiler (ADCP) data collected from the Marine National Facility RV Investigator voyage IN2024_V01, titled: "Multidisciplinary Investigations of the Southern Ocean (MISO): linking physics, biogeochemistry, plankton, aerosols, clouds, and climate." The voyage took place between January 02, 2024 and March 05, 2024 (AEST), departing from Hobart and returning to Fremantle.
Voyage was split into two as the drop keel location was moved without acquisition being stopped. WH75 was used for most of the voyage after OS75 stopped working on the 6th January. On the 23rd of February the WH75 failed, possibly due to water ingress into the cable.
ADCP data were collected using the University of Hawaii Data Acquisition System (UHDAS) and post-processed using the Common Ocean Data Access System (CODAS).
The RDI Ocean Surveyor OS150 and OS75 were run in narrowband mode (nb) and the RDI Ocean Surveyor WH75kHz ADCP was run in broadband mode (bb).
Internal triggering was used.
Both port and starboard drop keels are located approximately 6m below the water line, additionally both port and starboard keels were extended to:
• 0.0m from the start of the voyage until 4th January 23:40 (part-1 of the voyage)
• 1.2m thereafter until the end of the voyage (part-2 of the voyage)
Resulting in 6.0m and 7.2m below the water line respectively.

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