Model NOVA -New Generation Oceanographic Variable-Buoyancy Autonomous

SHARE

The NOVA (New generation Oceanographic Variable-buoyancy Autonomous) is an innovative subsurface profiling float. NOVA"s buoyancy control system is a closed system that requires no maintenance or service. A high-pressure pump is used exclusively to increase buoyancy by transferring fluid to an external bladder. Subsequently, a manifold valve is responsible for achieving negative buoyancy by decreasing the volume of the external bladder; the pressure differential between the internal and external bladders provides the necessary displacement for numerous ocean applications.

NOVA is extremely compact, lightweight (50 lbs), and does not require ballasting prior to deployment. NOVA is equipped with Bluetooth technology, which enables the end-user to communicate via wireless with the float before deployment, and to program duty cycles as the project requires. The various features of NOVA allow for effortless deployments from any vessel. NOVA is equipped with Iridium satellite telemetry, which allows for quicker, bi-directional, and more cost-effective data transmissions. NOVA is capable of operating autonomously for extended periods of time; 300+ profiles to a maximum depth of 2000 meters.
