Thetis Profiler

The Thetis Profiler is an autonomous moored profiler that is a submersible vertically profiling platform for use in marine to freshwater water bodies. The platform is designed to sample the water column distributions of physical, biological, chemical and optical properties at a fixed geographical location over extended periods of time, providing sub-meter scale vertical resolution over the water column. The Thetis design includes a modular, self-contained, winch-driven profiling platform with an integrated control system, a power system, and a telemetry unit. It is designed to carry a number of physical, optical and biological sensors, with expansion ports for up to a total of 8 instruments. Since the Thetis is a completely self-contained profiler the recovery, deployment and maintenance of the unit is greatly simplified.
