BioSalT™ is the commercialized version of the Compact-Conductivity Accessory for Profiling Systems (C-CAPS), which is being built for NASA. C-CAPS adds a conductivity-temperature (CT) probe to C-OPS, so water masses can be identified wherein temperature alone is inadequate, e.g., in the arctic or estuaries. The CT probe uses a state-of-the-art 4 electrode conductive element and patented circuitry. This is coupled with a fast response, high resolution thermistor with millidegree stability and resolution. The design is resistant to fouling and is flow optimized for the C-OPS profiler. BioSalT is a valuable addition to sampling objectives being pursued as part of continuing research associated with developing autonomous sampling capabilities. The present embodiment provides ideal water flow during vertical profiling, while protecting the sensing elements and adding minimally to instrument shadow. The sensor electronics are contained within the same housing as the BioPrOPS support electronics in the interior of the C-OPS backplane.
BioPrOPS™ is the commercialized version of the Compact-Propulsion Option for Profiling Systems (C-PrOPS), which is being built for NASA. C-PrOPS allows a C-OPS instrument to be maneuvered like a remotely operated vehicle (ROV), thereby allowing the profiler to be dynamically positioned away from a boat or shoreline and into the desired sampling location. Presently, the thrusters are mounted opposite the radiance aperture to minimize shading effects. In the future, the desire is to be able to execute programmable sampling options to further slow the descent rate of the profiler to improve surface loitering, and to stop the descent at a predetermined depth to prevent bottom impacts. C-PrOPS is also part of autonomous sampling research and development, wherein one or more thrusters function as a "winch" to haul the profiler to the surface for a free-fall descent. This concept is part of the NASA/BSI co-development called the Compact-Submersible Autonomous Winch (C-SAW).
