Progress Code: completed Maintenance and Update Frequency: asNeeded Statement: Data source: original field data. Data processing and quality control: Performed by Peter Shanks, O&A 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 IN2018_V05, titled: "How does a standing meander southeast of Tasmania brake the Antarctic Circumpolar Current?" The voyage took place from Hobart (TAS) to Hobart between October 16 and November 16, 2018. Data was collected during in2018_v05 for the duration of the voyage. Data was collected using UHDAS and post-processed using CODAS. Both the RDI Ocean Surveyor 150 kHz ADCP and the RDI Ocean Surveyor 75 kHz ADCP were run in narrow band. Internal triggering was used as external triggering was found to be unstable on previous voyages. The drop keel was at 6 m below the waterline for the duration of the voyage. See the voyage computing and electronics report for more details regarding data acquisition. This dataset was processed and then archived within the CSIRO Oceans and Atmosphere (O&A) Information and Data Centre (IDC) in Hobart.
