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. 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). {"type": "Polygon", "coordinates": [[[147.3388, -43.2862], [150.4905, -43.2862], [150.4905, -35.9798], [147.3388, -35.9798], [147.3388, -43.2862]]]} 147.3388 150.4905 -43.2862 -35.9798 5 minute ADCP os75nb Data (NC) documentDigital Download the 5 minute ADCP os75nb Data (NetCDF format) HTML Processing Report (PDF) documentDigital Download the Processing Report (PDF format) HTML Data Trawler documentDigital Link to Data available for this voyage via the Data Trawler HTML OS150nb Plots documentDigital Download overview plots of collected OS150nb ADCP data HTML OS75nb Plots documentDigital Download overview plots of collected OS75nb ADCP data HTML 5 minute ADCP os150nb Data (NC) documentDigital Download the 5 minute ADCP os150nb Data (NetCDF format) HTML Investigator Survey documentDigital Link to RV Investigator Survey Information, including voyage plans and summaries HTML Marine National Facility documentDigital Link to the Marine National Facility Homepage HTML Unnamed resource documentDigital License Graphic PNG
