The Triaxus is a towed undulating CTD used to collect horizontal profile measurements of the water column.
This state-of-the-art technology is made from carbon fibre, is hydrodynamically designed to be towed up to 3km behind the ship and to collect data quickly, while flying from the surface down to 300m in an undisturbed marine environment.
Scientists on board Investigator are able to control the flight path to develop a 2D picture of the ocean.
The Triaxus can be fitted with different types of instruments such as temperature, salinity and oxygen sensors, instruments to count and identify plankton, and equipment to estimate the amount of phytoplankton.
All of this information is sent to the scientists on board via a fibre optic cable in real-time.
