The voyage took place between May 28 and June 8, 2018 departing from Hobart (TAS) and arriving in Hobart. Data was collected during in2018_c01 for the duration of the voyage. Data was collected using UHDAS and post-processed using CODAS. Both the RDI Ocean Surveyor 150kHz ADCP and the RDI Ocean Surveyor 75kHz ADCP were mostly run in narrowband. However, for a small portion of the voyage both broadband and narrowband mode was used for data collection. Internal triggering was used. The drop keel extension was set at 1.19m thoughout, giving a transducer depth of 7.39m below the waterline for the duration of the voyage. Both units were switched on and off intermittently throughout the transit to survey site due to testing and configuration of the EM2040. When operational, both units operated mostly in narrow band with some bottom tracking. 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": [[[145.0, -43.3], [148.5, -43.3], [148.5, -38.5], [145.0, -38.5], [145.0, -43.3]]]} 145.0 148.5 -43.3 -38.5 Data available via Data Trawler documentDigital Data housed in O&A IDC warehouse available via Data Trawler HTML Information on RV Investigator survey 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 documentDigital Download ADCP Processing Report (PDF) HTML ADCP Data documentDigital 75KHz, 150KHz (normal and center beams) HTML Unnamed resource documentDigital License Graphic PNG
