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.

This dataset contains the Underway (UWY) data collected on Linnaeus voyage LI2014_V04. Voyage Title: IMOS mooring deployment and Rottnest Reference Station Monitoring The voyage took place on the 19th March 2014 from Hillarys (WA) to the Perth Canyon and return to Hillarys (WA) to recover two moorings and deploy two IMOS CTDs.
