Marine pollution such as oil spills, diesel emissions and micro plastics are a major ecosystem threats, and can be very harmful to marine animals. To detect and characterize pollutants near the surface of the water, including oil and diesel that may be caught under the ice, there is significant interest in developing an instrument that can be deployed remotely and can return information in real-time, either through a wireless link or through a tether. The aim of this project is to demonstrate the feasibility of applying existing technology in the areas of signal processing, underwater instrumentation, and underwater autonomous systems to demonstrate the feasibility of the system for different applications.
