This data set contains the imagery collected on the Marine National Facility (MNF) RV Investigator voyage IN2022_V09, titled ‘Valuing Australia’s new Gascoyne Marine Park’. The voyage took place between November 19, 2022 and December 19, 2022 (AEST), departing from Fremantle and returning to Fremantle, collecting imagery of benthic habitats together with oceanographic data. Instrument(s) used to collect this data: MNF Deep Towed camera (DTC) Datasets include: Video (oblique forward view) Stereo stills (oblique forward view) Navigational data

This record describes the Acoustic Doppler Current Profiler (ADCP) data collected from the Marine National Facility RV Investigator voyage IN2022_V09, titled: "Valuing Australia’s new Gascoyne Marine Park." The voyage took place between November 19, 2022 and December 19, 2022 (AEST), departing from Fremantle and returning to Fremantle. The ADCP was run for a notable part of the voyage, though it was turned off occasionally to avoid creating interference with the sounders and USBL. 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). Both the RDI Ocean Surveyor 150kHz ADCP and the RDI Ocean Surveyor 75kHz ADCP were run in narrowband mode. Internal triggering was used. The drop keel was set at 1.19m below the waterline for the duration of the voyage. Apart from the gap in the data, due to ADCP being turned on/off, and the usually required quality control data cleaning there were no significant ADCP processing-related issues encountered. To access the full voyage plan and other reports and data associated with this voyage, please see the contact information at the end of this report. This dataset was processed (quality-controlled), and then archived by the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC).

This record describes the Underway (UWY) data collected from the Marine National Facility (MNF) RV Investigator voyage IN2022_V09, titled: "Valuing Australia’s new Gascoyne Marine Park." The voyage took place between November 19, 2022 and December 19, 2022 (AEST), departing from Fremantle and returning to Fremantle. Standard Underway data is continuously recorded, consisting of: (1) Navigation data (NAV): Latitude, Longitude, Speed, Heading, Course Over Ground, Gyros, and Doppler Log (dual GPS instrument). (2) Thermosalinograph (TSG): Water Salinity, Flow-Rate, Temperature, Fluorescence, pCO2 and Optode/Oxygen. (3) Atmospheric (MET): Humidity, Wind Speed and Direction (vane and ultrasonic), Radiometer/Sea Surface Temperature, Pyranometer/Solar Radiation, Photosynthetically Active Radiation (PAR), Air Temperature, Air Pressure, Rain, Ozone and Trace Gases (port and starboard instruments). The quality-controlled RV Investigator underway meteorological and SST data are supplied to the IMOS AODN and other global data repositories and distributors, and made available for satellite SST validation by the Australian Bureau of Meteorology (BoM). Near real-time, unprocessed data are available via the link "Visualisation tool for Underway Data." This dataset has been processed (quality-controlled), and archived by the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC). Data are available at time intervals of 5 sec (NetCDF format), 5 sec, 10 sec, 1 min and 5 min (ASCII format). Note: not all variables are quality controlled; please check for existing QC flags in the datasets. Additional information regarding this dataset is contained in the Voyage Summary and/or the Data Processing Reports for this voyage.
