Thetis Profiler


 
General 
Product Name:Thetis Profiler
Product Description:The Thetis Profiler is a submersible vertically profiling platform for use in coastal marine and fresh water environments. The purpose of the platform is to sample the water column distributions of physical, biological, chemical and optical properties at a fixed geographical location over extended periods of time.
Year of initial development:
Year of latest version:2016
Area of application:The purpose of the platform is to sample the water column distributions of physical, biological, chemical and optical properties at a fixed geographical location over extended periods of time.
Field of Use:Vertical profiles of physical, biological, chemical and optical properties at a fixed geographical location. - Sub-meter scale vertical resolution from 1-2 m above the water floor to the surface in water depths up to 100 m. - Precise control of the profiler’s vertical position in the water column, especially in dynamic surface wave environments. - Able to “hide” in heavy seas. - Removes the need for a permanent surface buoy and mooring cable.
