This dataset contains the Underway (UWY) data collected on Linnaeus voyage LI2014_V23. Voyage Title: Transit Hillarys Boat Harbour to Fremantle. The voyage took place on the 3rd December 2014 from Hillarys boat harbour returning to Hillarys boat harbour. The Underway (=continuously recorded) dataset from this research voyage includes Navigation (NAV), Sounder, and se-surface temperature data. NAV data includes GPS (Global Positioning System) measurements of latitude, longitude, ship's direction and speed. Data are stored at 5 second intervals (NetCDF) and both 10 second 5 minute intervals (.csv format), including a 10 second PDR (Precision depth recorder) file in .csv format. Additional information regarding this dataset is contained in the data processing report for this voyage.

This dataset contains the Underway (UWY) data collected on Linnaeus voyage LI2014_V15. Voyage Title: IMOS Mooring Service. The purpose of this voyage was to undertake monitoring of the Rottnest Island National Reference Station and to find a location for a new IMOS mooring site. The voyage took place on the 30th September 2014, from Hillarys (WA) to the Perth Canyon and return to Hillarys (WA) to service two IMOS moorings. The Underway (=continuously recorded) dataset from this research voyage includes: NAV data. NAV data includes GPS (Global Positioning System) measurements of latitude, longitude, ship's direction and speed. Data are stored at 1 second intervals (NetCDF) and both 10 second and 5 minute intervals (.csv format). Additional information regarding this dataset is contained in the data processing report for this voyage.

This dataset contains the Underway (UWY) data collected on Linnaeus voyage LI2015_V11. The voyage took place on the 7 May 2015 from Hillarys Boat Harbour (WA) to Rottnest Island and back to Hillarys (WA) on the 7 May 2015. Voyage Objectives: Servicing the Rottnest Island National Reference Station. There were no CTD deployments undertaken during the voyage. Fluorometer sensor data were not collected on this voyage due to sensor fouling from the previous voyage. Water depth data and TSG data were not collected on this voyage. Data are stored at 1 second intervals (NetCDF format) and both 10 second 5 minute intervals (.csv format), including a 10 second PDR (Precision depth recorder) file in .csv format. Additional information regarding this dataset is contained in the data processing report for this voyage.

This dataset contains the Underway (UWY) data collected on commercial ferries plying the Rottnest to mainland route. Voyages take place on a commercial schedule. A Seabird SBE38 sensor is permanently mounted on the ferry in the engine cooling waster intake. A monitoring computer records sea surface temperature whenever the vessel achieves more than a minimum preprogrammed speed over ground. Position is determined from a GPS unit. Data is transmitted to CSIRO Marine and Atmospheric Research centre in Hobart on the hour every hour. The vessel traverses the route from Hillarys Boat harbour to Rottnest 3 or four times per day except during a winter vessel maintenance period. This dataset has been processed and is archived within the CSIRO Marine and Atmospheric Research Data Centre in Floreat.

3D plume mapping was conducted over a 10day period at Chevron's Wheatstone dredging operation near Onslow Western Australia. Dredge plums created by a cutter suction dredge were sampled from CSIRO vessel RV Linnaeus on voyage number LI2013_v25. Underway measurements were made using a ship mounted ADCP to measure vertical velocity profiles and backscatter intensity and DALEC that measured the spectral qualities of incoming and reflected sea surface light. Profile data were collected using LISST (particle size distributions), CTD (backscatter, temperature and salinity), Hydroscat, Hydrorad (used measure light profiles, extinction coefficients , and scattering properties). Surface and bottom water samples were be collected at selected sites and analyzed for particle size distributions
