The Oceanic Remote Chemical Analyzer (ORCA) is an autonomous moored profiling system providing real-time data streams of water and atmospheric conditions. It consists of a profiling underwater sensor package with a variety of chemical and optical sensors, and a surface mounted weather station, solar power system, winch, and custom computer and software package equipped with WIFI/cellular communication.

Since its deployment in 2000, the ORCA system has provided a near-continual stream of high-resolution water quality data from locations in the Puget Sound, Washington State. There are currently 6 mooring systems deployed, spread throughout Puget Sound and Hood Canal.
