The voyage took place between 15 May to 16 June 2017, departing from Bell Bay (TAS) and arriving in Brisbane (QLD). Only the RDI Ocean Surveyor 75kHz ADCP was operational during this voyage. The system was turned off during net/instrument tows to ensure it didn’t interfere with the USBL. The RDI Ocean Surveyor 150kHz ADCP was not operated due to a hardware fault, so all data was collected with the RDI Ocean Surveyor 75kHz ADCP, which was run in narrow band and broadband modes, depending on the ocean dept0068. Internal triggering was used as external triggering was found to be unstable on previous voyages. The drop keels were typically used at flush with Gondola (2m). The ship’s officers raised concerns about the keel locking pins getting damaged in rough weather, consequently the keels were retrieved to flush with hull during rough weather transits. 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. {"type": "Polygon", "coordinates": [[[146.7, -41.8], [154.7, -41.8], [154.7, -23.5], [146.7, -23.5], [146.7, -41.8]]]} 146.7 154.7 -41.8 -23.5 Data available via Data Trawler documentDigital Data housed in O&A IDC warehouse available via Data Trawler HTML Information on RV Investigator surveys documentDigital RV Investigator survey information including voyage plans, summaries and metadata records HTML Marine National Facility (MNF) documentDigital Marine National Facility web page HTML ADCP Processing Report: in2017_v03_ADCP_Processing_Report.pdf documentDigital HTML ADCP Data (NetCDF os75bb and os75nb) in2017_v03_os75.zip documentDigital HTML MNF Voyage Plans and Summaries documentDigital Download MNF Voyage Plans and Summaries HTML Voyage Plan (pdf) documentDigital HTML Voyage Summary (pdf) documentDigital HTML Voyage Highlights (pdf) documentDigital HTML View plots os75bb (index.html) documentDigital Overview of the ADCP OS75 Dataset (Zipped HTML) HTML View plots os75nb (index.html) documentDigital Overview of the ADCP OS75 Dataset (Zipped HTML) HTML Unnamed resource documentDigital License Graphic PNG
