The in-line system samples in-coming water (via the ship’s cooling system) at 1Hz with a Seabird SBE45 thermo-salinograph (TSG), a Wetlabs combination fluorometer turbidity sensor (FLNTU), and a GPS stream from a 12 parallel channel Leica GPS Smart Antenna. Digital output from all the instruments are ported to an industrial fanless computer that is set-up alongside the sensor packs in the engine room. Incoming digital data from each sensor is managed via Labview software, and stamped by the PC clock to facilitate melding of data files. Travelling at ~20 knots a 10 second average corresponds to sample “grabs” at every 100m along the ship track. Such high repeat sampling provides an unprecedented capability to monitor ecosystem dynamics down to weather band responses. The shiptrack is well located to assess dynamics of bay and adjacent ocean exchanges, Bass Strait conditions, upwelling off western Bass Strait and the Mersey Estuary conditions.
