The voyage took place between January 02, 2024 and March 05, 2024 (AEST), departing from Hobart and returning to Fremantle. Voyage was split into two as the drop keel location was moved without acquisition being stopped. WH75 was used for most of the voyage after OS75 stopped working on the 6th January. On the 23rd of February the WH75 failed, possibly due to water ingress into the cable. ADCP data were collected using the University of Hawaii Data Acquisition System (UHDAS) and post-processed using the Common Ocean Data Access System (CODAS). The RDI Ocean Surveyor OS150 and OS75 were 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 to: • 0.0m from the start of the voyage until 4th January 23:40 (part-1 of the voyage) • 1.2m thereafter until the end of the voyage (part-2 of the voyage) Resulting in 6.0m and 7.2m below the water line respectively.

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": [[[113.2462, -67.0026], [151.4171, -67.0026], [151.4171, -31.9323], [113.2462, -31.9323], [113.2462, -67.0026]]]} 113.2462 151.4171 -67.0026 -31.9323 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 OS75nb Plots documentDigital Download overview plots of collected OS75nb ADCP data HTML OS150nb Plots documentDigital Download overview plots of collected OS150nb ADCP data HTML 5 minute ADCP os150nb Data (NC) documentDigital Download the 5 minute ADCP os150nb Data (NetCDF format) HTML 5 minute ADCP wh75bb Data (NC) documentDigital Download the 5 minute ADCP wh75bb Data (NetCDF format) HTML WH75bb Plots documentDigital Download overview plots of collected WH75bb ADCP data 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
