Company

Turo Technology is a privately held business based in Hobart, Tasmania, Australia.  Turo has been operating since 1991, providing specialised oceanographic and water quality instrumentation.

Original compact drifting bouy

Turo began by designing and manufacturing a new series of satellite tracked oceanographic and meteorological drifting buoys. These were sold to organisations such as the Australian Antarctic Division and the Australian Bureau of Meteorology.

In 1994 Turo embarked on a program of diversification into water quality instrumentation.  This was facilitated through a strategic alliance with Yeokal Electronics Pty Ltd of Sydney, Australia.

Hundreds of the original T-611 Water Quality Analyser have been sold. The T-611, a range of other water quality products and custom designs were sold world wide.

Consulting and major projects followed, including the design and implementation of all the software for a major desalination facility's offshore outflow.

The popular T-611 Water Quality Analyser

With the launch in 2007 of the Turo Devil XBT data acquisition and recording system, Turo has returned to oceanographic instrumentation.  The Devil XBT, and the successful Quoll XBT, have been adopted quickly and now have users in oceanographic research, defence, meteorological, survey and consulting industries.

Today Turo focuses on its XBT recorder systems and processing software.

Climatology Assisted Calculated Sound Speed

Calculating sound speed from XBT temperatures is a standard procedure. This typically involves setting a particular fixed value of salinity to be used in the calculations, usually 35 psu. This assumes salinity deviation will not lead to unacceptable sound speed errors.

Turo XBT software uses advanced algorithms to extract a salinity profile from the climatology database - a salinity profile for the given latitude and longitude and for the given seasonal time of year. This salinity profile is then used with the XBT temperature profile to derive a sound speed profile.

Operator selectable options enable either climatology assisted or standard fixed value calculations.

The following clearly illustrates the potential improvements. In this example at 200 metres depth the standard method is improved upon by >1 m/sec and possible distortion is improved over the whole profile.

Turo Quoll XBT-sv Recorder

Supports XBT and XSV probes.

With all the features of Devil XBT and Quoll XBT Recorders, the Quoll XBT-sv delivers the next level of functionality - support for XSV probes (Expendable Sound Velocity).

Quoll XBT-sv produces sound speed profiles directly from XSV probes or calculated from XBT probes. Calculated sound velocity uses classical nominal salinity method or Turo's Climatology Assisted Sound Speed Calculation.

Easy to use and incorporating the familiar quality control using a global climatology database and behaviour models to flag possible anomolies - and more:
