Thetis Profiler

Product Name:Thetis Profiler
Product Description:
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.
