MacArtney has supplied second TRIAXUS ROTV system for use on the Australia’s Marine National Facility research vessel, the RV Investigator.

This TRIAXUS E version features a higher payload capacity and enables the installation of a wide range of sensors targeted to the specific needs of oceanographic research, the company explained.

The scope of supply from MacArtney includes the TRIAXUS extended E version, the Sea-Bird SBE 911 conductivity, temperature and depth instrument (CTD), a transmissometer to determine the excitation of the water medium to gauge clarity at ranging ocean depths, a fluorometer to measure the parameters of Chlorophyll a to provide data on concentrations of algae in the water column and a PAR Sensor or Photosynthetically Active Radiation sensor to determine photon energy available for the photosynthesis processes in the water column.

Custom sensor packages supported by the NEXUS fibre optic multiplexer and MMI (Man Machine Interface) mean the TRIAXUS can be programmed topside to perform various functions and undulations whilst being towed. Fibre optic umbilical cabling allows for the feedback of data in real time.
