This record describes the Acoustic Doppler Current Profiler (ADCP) data collected from the Marine National Facility RV Investigator voyage IN2023_V07, titled: "SWOT-ACC: smaller scales of the Antarctic Circumpolar Current in a meander south of Tasmania." The voyage took place between November 15, 2023 and December 20, 2023 (AEST), departing from Hobart and returning to Hobart.

The OS75 was not turned on due to the degraded performance, the WH75 was installed on the starboard drop keel to make up for the faulty OS75 and worked well for the duration of the voyage. The OS150 operated normally.

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 OS150kHz was 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 by 1.2m for the entire duration of the voyage, subsequently the transducers were located approximately 7.2m below the water line.

For more information please see the Processing Report (linked below).

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