Several compact sampling platforms have recently been developed or are gaining widespread use in Naval operations and oceanographic research. In addition to limited sensor payloads, many of these platforms are autonomous and intended for extended deployments. Sensors compatible with these platforms must therefore be compact, low power, and able to accommodate effective anti-biofouling measures. Developing optical sensors with these qualities for use in Naval operations and oceanographic research is a core long term goal. Beam attenuation is of particular interest because it is a fundamental Inherent Optical Property used in many Naval applications, including estimates of diver visibility and vulnerability, and predicting the performance of optical MCM identification systems. Attenuation is also widely used in determining particle concentration, particle composition, and water clarity.
