Maintenance and Update Frequency: asNeeded Statement: Original field data. Data processing and quality control: Performed by Vito Dirita, NCMI DAP Group. Note that 1min average data is provided as a special request, however it is unedited and has data quality implications. For general use, the 5min average data (os150nb.nc) should be used.

This record describes the Acoustic Doppler Current Profiler (ADCP) data collected from the Marine National Facility RV Investigator voyage IN2020_V01, titled: "Development of William’s Ridge, Kerguelen Plateau: tectonics,hotspot magmatism, microcontinents, and Australia’s Extended Continental Shelf." The voyage took place between January 10 and March 6, 2020, departing from Freemantle and returning to Freemantle. The primary scientific operations of the voyage were multibeam survey, seismic lines and dredging of the William’s and Broken Ridge features. ADCPs were turned off intermittently to avoid interference with multibeam during surveys. On Jan the 15th the OS75 was reporting excessively high temperatures. According to Uni of Hawaii, this is most likely due to water ingress into the transducer indicating potential failure. Temperatures eventually settled at full-scale (~97 deg C), which had a significant effect on calculated water velocities. Soundspeed was manually ...
