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). {"type": "Polygon", "coordinates": [[[147.3305, -56.8626], [154.2919, -56.8626], [154.2919, -42.8424], [147.3305, -42.8424], [147.3305, -56.8626]]]} 147.3305 154.2919 -56.8626 -42.8424 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 (PNG) documentDigital Download overview plots of collected OS150nb ADCP data (PNG format) HTML 5 minute ADCP os150nb Data (NC) documentDigital Download the 5 minute ADCP os150nb Data (NetCDF format) HTML WH75bb Plots (PNG) documentDigital Download overview plots of collected WH75bb ADCP data (PNG 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 5 minute ADCP wh75bb Data (NC) documentDigital Download the 5 minute ADCP wh75bb Data (NetCDF format) HTML Unnamed resource documentDigital License Graphic PNG
